Imperial College land & Warren Farm ‘rewilding’. A plea to Councillors to vote no & start over.

Imperial College have come out with a statement today saying they have no plans for sports grounds on their land in the controversy surrounding Ealing Council’s ambitious plans for sports and ‘rewilding’ at Warren Farm. The truth is that Imperial College land entering the scheme is currently a trashed, horse grazed paddock next door to Warren Farm. The Council can only get away with calling this entire scheme ‘rewilding’ because they are going to allow this single paddocked area to rewild. It will take 10-15 years. Many species will be lost in that time. Meanwhile Warren Farm itself has been rewilding for well over a decade and is now an incredibly precious ecosystem as a result of that time for nature to recover. Destroying half of Warren Farm for soccer pitches nobody needs and cricket pitches that could be placed elsewhere is not acceptable in a climate and biodiversity crisis.

Imperial College are being used as pawns in this flagrant ‘up yours’ to the Council’s own Biodiversity Action Plan and as tokenistic mitigation. It’s like chopping up ancient woodland with 500 year old Oak trees and saying you’ll plant the same number of Oak saplings in their place. It’s simply not equivalent and makes no sense when we have alternative sites for sports available. Biodiversity value comes with scale, intactness and age. It’s also not a good look for an organisation like Imperial hoping to boost their green credentials so I would strongly advise their legal and PR team take a closer look at how this will impact their reputation.

Council leaders are quite incredibly pushing through a plan tonight which has been vocally opposed by the majority of respondents in their public consultation, over 15,000 respondents to the Warren Farm Nature Reserve petition, our 5,500 members of Ealing Wildlife Group and most worryingly they’ve shown they don’t have a clue about very basic ecological principles. Nor it seems will they listen to experts or evidence on the matter. It begs the question why they are stubbornly proceeding with a plan that virtually everyone but them objects to? Is there an ulterior motive? How is it acceptable to ignore and silence objection on this, and then brazenly state it’s democratic. It boggles the mind.

I’m all for social justice and new sports facilities for children and communities in need, but in appropriate locations that don’t destroy incredibly complex ecosystems and rare species. Ones that cannot exist elsewhere and cannot survive on the crumbs left behind when this Council barges its plans through effectively halving the space for Skylarks, Barn Owls, rare plants, Slow Worms, Bats and all the people that want to enjoy Warren Farm as it is. The fact is they won’t survive. A vital urban oasis needs protection. Chipping away bit by bit at these last refuges are why we are one of the most nature depleted countries in the world!

There is still a chance to halt these plans and start from scratch with a solution that favours sports for children as well as saving our last Skylarks and all the other species that rely on this land. I challenge Councillors voting tonight to vote no and let’s start discussions together from scratch, respectfully and collaboratively. Let’s bring children from Southall schools to Warren Farm together and teach them about the unique wildlife that lives there. And let’s ask them if they’d like cricket and football pitches to be installed there, or at one of the 7 other sites earmarked as suitable in the Council’s sports review last July. One of the seven sites that are wholly more suitable and won’t destroy the precious little urban nature we have left.

Our Council leaders say they have to find a compromise. This is the only acceptable compromise.

An EWG statement on the proposed future of Warren Farm

Following publication of plans (https://www.aroundealing.com/news/warren-farm-nature) to reinstate sports facilities at Warren Farm by Ealing Council leader Cllr Peter Mason which claims the compensation will be Local Nature Reserve (LNR) status for the remainder and a newly acquired field alongside, we wish to put out a response ASAP:

A tweet from the Council on the topic

“I’m very disappointed that our leaders are pushing on with plans to destroy half of one our most biodiverse habitats in the borough, home to many rare species and the only site in Ealing where Skylarks can breed, a red listed bird of highest conservation concern. Having contributed to Ealing’s Biodiversity Action Plan (BAP) which vows to protect and enhance habitat for this rare bird it’s shocking to hear that it’s apparently either Skylarks or sports facilities for children. This is disingenuous and misleading. We can have both. It’s also extremely concerning to see a real misuse of the term ‘rewilding’ when the plans involve the opposite, de-wilding. Warren Farm has already rewilded. It’s ecocide to undo that process.

Warren Farm is not the place for sports facilities. And Natural England will categorically not grant this plan for Local Nature Reserve status when it will cause local extinction of this precious Skylark population if it goes ahead. There are lots of sports grounds that children can use, and far more suitable sites to make new ones that won’t obliterate nature on such a concerning scale. There’s only one place in Ealing where we can show children Skylarks, an indicator species for a really rich and valuable ecosystem. I’m sure many children would agree to save this amazing natural asset we are lucky to have on our doorstep, and if they had a vote, would ask their Council leader Peter Mason to reconsider this ill thought out plan. It’s stubborn, ignoring the overwhelming consensus of the local community and undermining democracy at worst, and ecologically illiterate at best. 

The Council needs to listen to experts on this if their Climate and Ecological Emergency policy or Biodiversity Action Plan (BAP) mean anything at all. Skylarks, Barn Owls, Slow Worms, rare plants and insects, Bats and many other threatened species rely on this whole vast site to thrive, not a damaged portion of it left after new sports facilities swallow it up and leave the remainder for wildlife to share and make do with alongside a more concentrated public using the site currently for exercise, recreation and enjoying nature. The remainder will be a poor replacement and wholly unsuitable for Skylarks who need the large scale meadows currently there to avoid predators, as they are vulnerable ground nesting birds. 

Skylark at Warren Farm by Nigel Bewley

I’m urgently meeting with Cllr Deirdre Costigan and head of parks Chris Bunting next week to discuss implementation of the BAP and how we have got to this stage with Warren Farm as well as wider targets to protect and improve Biodiversity across the whole borough. Ealing Wildlife Group has been very collaborative with the Council over the years to achieve these aims together so we are extremely concerned for our collaborative future with this announcement. I would urge all Councillors to seek expert advice before believing some of the PR spin here being touted as a victory for Warren Farm and its wildlife when the reality couldn’t be further from the truth.

Ealing’s Hedgehog Highways project launch. Can you help?

Blog post by Natasha Gavin, EWG Hedgehog project lead

When I was growing up in Ealing, it was a rare treat to see a hedgehog. In fact I only saw one once, when I was 12 yrs old, in South Ealing. I tried to pick it up, and that REALLY hurt. I learnt a life lesson: let wildlife be wild. No iPhones back then. Just a vivid memory remained 😉

Fast forward 30 odd years, it’s even rarer to see a hedgehog in Ealing. Or anywhere. Numbers have declined roughly by 2/3 since my first and only sighting of a live hedgehog. But trail cameras now mean I know they exist, in smaller numbers, but in urban safe havens- I have watched dozens of prickly mummies feeding their baby hoglets, in compost heaps, piles of leaves and back gardens all around our borough. As nocturnal creatures, you are unlikely to spot them coming out to feed, but affordable clever technology means we can capture their movements. And then we can help them to thrive.. or at least survive.

What does EWG have planned in our hedgehog project? 

Hanwell Hedgehog by James Morton

ZSL (Zoological Society of London) have been surveying hedgehogs across London for 5 years as part of their London Hogwatch project. We have commissioned them (using grants secured by our one lady fundraising team, thank you Sandra!) to help us survey populations in three hog hotspots across Ealing: Pitshanger Park, Brent Lodge Park (aka the Bunny Park) and Elthorne Park and Extension. ZSL will install about 30 cameras in those parks next week (as hedgehogs venture out to eat as much as possible before hibernating) and review all footage for us after a two week period. We will feed back to EWG members via informative online talks during this project- so watch this space.

We’d like to thank our friends at the Charity of William Hobbayne for getting in touch with us proactively to ask if there were upcoming conservation projects they could help support us on in Hanwell, and The Freshwater Foundation for awarding us further funds to get the local community across the whole Borough of Ealing involved in helping hedgehogs and connecting our green spaces and gardens to allow wildlife like hedgehogs to get around the borough and continue to thrive.  

EWG is also partnering with ZSL to deliver a citizen science project- that’s where you can help. 

How can you as an EWG member be involved in helping hedgehogs?

Phase 1

  1. ZSL will lend us a number of extra cameras, for private residents to use in back gardens adjacent/ in close proximity to the Parks above. Cameras would be loaned for a two week period and EWG members would be asked to review all footage at the end of the period. (The cameras only record for very short bursts when triggered by motion at night so this would not be too onerous.) Get in touch ASAP with me if you are interested in hosting a camera natashagavineo@gmail.com 
  2. We are looking for a Hedgehog champion in each of the three areas. This will involve coordinating and monitoring where private cameras are at any time, and ensuring their safe return to ZSL (via me) at the end of the project. It could also involve helping with phase 2 of this project. 
  3. Report any hedgehog sightings (recent or historic) to Greenspace Information for Greater London here: https://www.gigl.org.uk/submit-records/submit-a-record/ 
  4. Talk to your neighbours now about how to help hedgehogs: create holes in fences between gardens, leave wild corners, provide fresh water, leave out cat food in Spring/Summer months, ensure ponds have escape ramps and stop using horrid pesticides like blue slug pellets.
Tash Gavin, Hedgehog project lead with her very own hedgehog highway

Phase 2

  1. Once we have a better picture (no pun intended) of where the hedgehog highways are (or should be), our dedicated team of hole makers will offer to create CD sized holes in fences, where permission by fence/ wall owner is given. The grants from Freshwater Foundation and The Hobbayne Trust will be used to purchase all necessary equipment- all we need are DIY lovers. So please come out of the woodwork..:)
  2. We will be doing some hedgehog focused habitat management and creation task days for volunteers who want to get involved in a hands-on way. With some of the funding kindly provided by The Hobbayne Trust we will be initially focusing on making the Hobbayne Half Acre site near Hanwell Viaduct a model reserve for hedgehogs to thrive. All ages and abilities welcome to come help. Volunteer dates to follow. If you’d like to keep up to date then please sign up to our volunteer mailing list here: https://ealingwildlifegroup.com/get-involved/volunteering/
  3. We will be running a public information campaign in Spring/Summer 2023- if you want to help with that do let me know. It will involve outreach work, and probably talking to families and children- every child should be able to see at least one living hedgehog during their childhood, shouldn’t they? I have seen three dead ones in the last year. 

Please help us to change that. Any Hedgehog Heros please contact me natashagavineo@gmail.com

Success! The Peregrines have fledged!

It’s been two years in the making but at long last, the Ealing Hospital Peregrines have successfully fledged 3 chicks! Two females and one male as far as we can tell., and all are strong and healthy and flying around the hospital!

How it started/ How it’s going. Photos by Sean McCormack (L) and David Gordon Davy (R)

There is a photo gallery that tells their story here

And to read more about this incredible journey, take a look at this guest blog Sean wrote for Animal Journal!


We will keep you updated on our peregrine family, we can track the chicks as they are all ringed. I wonder where they will end up?

Would you like to host Swift nest boxes with your neighbours? We’re looking for Swift street champions!

In recent days the Swifts are arriving back in Ealing! We have pretty much completed phase one of our Swift project, with about 60 boxes already up and ready for inspection by adult breeding pairs who have returned to find their traditional nest site no longer present or accessible. As well as first year breeding birds looking to set up home.

If anyone would like Swift nest boxes installed as we reach phase two of the project, then drop us a line on hello@ealingwildlifegroup.com with your name, street address and whether you’ve seen swifts or know they are breeding nearby.

For efficiency and cost saving with our contractor we are looking to find Swift champions who will recruit 5-10 neighbours on their street or in the immediate vicinity who would each host 1-3 boxes on their houses. And a calling system or two on each street as well. We hope to get phase two complete by July when young birds will start inspecting potential nest cavities for when they return in 2023.

Phase three will be the individuals who have already been in touch who want boxes they already have erected on their house only, or wish to host one or two of our boxes on their own home. If you can be the Swift champion for your neighbourhood and offer a home for lots of boxes then we can get to you quicker. So get in that neighbourhood Whatsapp or Facebook group and gauge interest.

We would love to host more boxes in Acton, Northolt, Greenford and Southall so offers from these areas will now be prioritised.

The Dawn Chorus

WHY DO BIRDS SING SO GAY?

(from the song, “Why Do Fools Fall In Love”, originally by Frankie Lymon & The Teenagers.)

Wren singing, by Caroline Farrow

It’s just after five in the morning and I’ve been up an hour. It’s getting lighter by the minute and getting noisier, too. I’m an early bird today because I’m sound recording the dawn chorus, on International Dawn Chorus Day, 1 May 2022. And it sounds sublime.

On my garden terrace, which overlooks Hanger Hill Park, I’ve set up a pair of microphones running to a sound recorder in the house. I’m inside, with the recorder, to keep warm although it is a very mild morning. The main reason is so as not to add any of me to the recording. I just want the birds as they make themselves heard over the sound of the A40. Even at dawn on a Sunday morning the sound of the A40 is there. Ordinarily, when I’m in the garden, I tune out the sound of the road that is about half a mile away. Microphones, however, can’t do that and hear all. But the sound of the vehicles making their way in and out of London is also part of the recording. The birds live with the A40: it’s an urban dawn chorus. They will sing whether it’s there or not. But why are they singing in the first place? They are not singing for me….

A very enthusiastic robin singing, by Caroline Farrow

The dawn chorus commences about an hour before sunrise and not all of the birds start singing at the same time as if from a musical director’s cue. If I overlooked Warren Farm, one of the first to start singing would be skylarks – there’s some truth to the saying, “up with the lark.” Hanger Hill Park doesn’t have any skylarks but there are plenty of robins, dunnocks, blackbirds and song thrushes to start the chorus off. Corvids join in and smaller, more delicate, birds such as warblers and wrens that are more sensitive to a chilly dawn pipe up when the singing is well underway. Even tawny and little owls may join in along with rhythmical accompaniment from great spotted woodpeckers as they drum in support. (Males hammer against dead trees and other resonant objects to proclaim territory ownership. One regularly uses a nearby ‘phone mast.)

Skylark singing, by Caroline Farrow

As Dawn’s rosy fingers put the stars to flight it’s still pretty dark and foraging for food is difficult. What better time to sing for a mate or reinforce territory ownership? Singing in broad daylight can be dangerous because it risks the attentions of a predator. It’s best to advertise in dim light before the singer’s position is betrayed. The air is often still and more humid at dawn allowing birdsong to travel much further. (It seems to make the A40’s presence more apparent, too!) As the light strengthens the dawn chorus diminishes as birds drift off on the hunt for food. Singing is hard work and depletes energy reserves which may be at a low ebb after a night’s roost. It is the fittest, best-fed males who sing the strongest, loudest, longest and most impressive song. Females choose a mate who sings best, because such a male is more likely to be good at raising chicks, to have a good territory, or to pass successful genes to their young. In many species, once the female has been attracted, the male will sing less often. A bird that sings on and on, late into the season, is probably a lonely ‘bachelor’ who has failed to attract a mate or perhaps an already paired-up male looking to hook up with another female as with dunnocks with their notoriously complicated ‘love lives.’

A young blue tit, eating and singing, by Caroline Farrow

The dawn chorus is well worth getting up for or, if you are a night-clubbing, gig-going raver delaying getting into bed for! Listen to the dawn chorus stereo recording that I made, perhaps in its entirety (it’s just over 45 minutes) or just dip in and out. Whichever way you listen simply enjoy nature’s songsters. They will gladden your heart.

The recording was made with a matched pair of AKG C451E microphones, with CK1 capsules, in Rycote Softie windshields. The microphones were arranged as a spaced pair. The digital recorder was a Marantz PMD661 and the file format was WAV with a sampling rate of 48kHz at 24bits. The listening mp3 file is barely edited – faded in and out only.

Could you be an Ealing Swift champion?

We’re very excited to have exceeded our funding goal to help save Ealing’s Swifts. If you’re not aware of the campaign you can read more here.

But now, we are looking for interested residents, business and organisations who would be happy to host some of our swift nest boxes ahead of their summer breeding season this year. We’re especially interested in public buildings where they can be enjoyed by many. If you’re interested or have a site in mind please read the following to make sure it’s suitable and then drop us a line on hello@ealingwildlifegroup.com.

By hosting some of our Swift nest boxes you’ll be helping this iconic summer visitor and now red-listed bird remain as a thriving species in the borough of Ealing for future generations to enjoy. 

We have a few requirements we hope you can meet to be part of the project which we will outline here. It’s important we have suitable sites and full commitment from one or two Swift champions at each site to ensure the success and sustainability of the project. 

As we have had a good response from interested parties, we’re asking that you run through this list and self-select whether you think your site might meet these requirements before we arrange a visit. We’re happy to chat through any concerns or minor points that might not fully satisfy the list on a case by case basis either by email or phone. 

Physical requirements:

  • A North, East or North-East facing wall on a building to erect boxes
  • Space for at least three, but preferably five boxes at least 0.5m apart
  • A sheltered position under a ledge or eaves if possible
  • A drop of at least 5m height underneath each box, free from any physical obstructions to allow young swifts to drop and take their first flight without becoming grounded
  • In some sites we may wish to host a public education sign or information board to showcase the project and educate about Swift conservation and wider biodiversity

Logistics:

  • Permission from building owners to erect long lasting nest boxes onto the building, affixed using screws and other hardware drilled into the brick or woodwork
  • Access to site with high ladders and/or cherry picker equipment as needed
  • Depending on sites, you may prefer to erect the boxes yourself rather than have our contractor visit to do so (please let us know if this is the case)
  • Ideally we want to get boxes up by the end of April 2022, but some sites may have to be later (young swifts will still check out boxes put up later in summer)

Swift champions:

  • One or preferably two people per site who will act as point of contact for us at EWG
  • Willingness to act as a Swift champion, educating and advocating for Swift conservation at each site and with any residents, occupants, visitors etc 
  • Responsibility to operate calling systems during key periods to attract Swifts to the boxes in the early phase of the project, anticipated to be at least three seasons in early and late summer when Swifts are arriving from and preparing to leave for Africa

Calling systems:

  • We will supply a small electronic device that plays the sound of Swifts at each site to try to recruit returning adult Swifts that are looking for a nest site or have been displaced from a previous one, as well as young Swifts thinking about a nest site for the following summer
  • We can also supply a Swift call CD or MP3 digital file for you to play if preferable
  • Calling systems need to be played in close proximity to the nest boxes to attract passing Swifts to investigate as they like to nest in loose colonies
  • The electronic box can be placed outside on a wall or window ledge and the wire looped back through a window. It needs to be plugged into a USB socket or plug adaptor in order to work and can be placed on an automatic timer. We can provide what is needed at each site
  • Calling system volume can be adjusted, but ideally would mimic the natural sounds (and volume) Swifts would make around the nest site anyway
  • If there are concerns around noise the calling systems can be played at certain times of day only
  • Ideally they should be played for an hour or two in the morning and evening at peak Swift arrival time in late April/early May, and again when young Swifts are on the wing and preparing to leave in late summer (late July/August)
  • We can advise on this on a case by case basis, but the use of calling systems for the first few years of a project until Swifts are established in boxes and the site becomes attractive in its own right to passing swifts is a vital part of the success of the project
  • We’re hoping you can accommodate the calling system until Swifts take up residence but do let us know if there are any concerns about this so we can find a solution that works for everyone

Monitoring:

  • Any Swift sightings and breeding records should be submitted both to EWG and Greenspace Information for Greater London (GiGL) each year to support ongoing monitoring of Swifts in Ealing
  • We will set up an easy system to do this
  • We would also ask that we can visit the site to observe and monitor Swift activity, and if appropriate bring the public to see the boxes if they are successful in attracting breeding Swifts in future

We hope all of the above is reasonable and can be accommodated. Please let us know if your proposed site meets the requirements or get in touch if you have any concerns or queries. 

If you have a site in mind or would like to suggest one, ask more questions or volunteer with the project then please drop us a line on hello@ealingwildlifegroup.com

‘The Harvest Mouse’ by Maria Lundy

The Harvest Mouse

Running along grasslands green

The smallest rodent goes unseen,

At the woodland edge they stop to feed

On Fruits, flowers, and types of seed

A field of hundreds and there’s more

spread around the farmyard floor

Our fur and white belly reflect our kind

and Camouflage, so we are hard to find,

with rabbits, bats and water vole

we are found near the stoats and European mole.

A field of a hundred and a handful more

spread around the farmyard floor

Builders come and chase us away,

with bricks and houses day by day,

The harvest mice we start to hide

In the ever-decreasing countryside.

A field of fifty and no more

Scattered about the farmyard floor

The fields and farms are fading fast

The beds and hedgerows don’t seem to last,

The cereal crops we cannot see

are left as a lonely plant or tree.

A field of twenty and no more

Scarce about the farmyard floor 

So now we are placed around the UK

To conserve our breed and be ok,

Plant us crops, chemical free

Bring your binoculars and look for me,

In fields in Ealing, and plenty more

Around the farmyards, close to your door.

Save Ealing’s Swifts!!

Swift illustration by @mx.momac on Instagram

One of the biggest thrills of spring is when the beautiful and acrobatic swifts return to the UK after a long and perilous journey from Africa.  They tell us that summer is on its way soon and that all is well with the world.  

The sad fact is that Ealing’s swifts, like swifts across the UK, are in serious decline.  Swifts spend their winter in Africa and return to the UK in April with their lifelong partner and offspring to breed in the same area as last year.  Swifts are used to living alongside humans, but modern building design and the refurbishment of old buildings have been depriving them of the nooks and crannies that they use for nesting sites. 

The Saving Ealing’s Swifts project is to combat the decline of swift nesting sites.  Ealing Wildlife Group is planning to erect 150 nest boxes to boost existing colonies of swifts and attract new colonies. The nest boxes will be sited on public buildings across the borough, with signage to tell the public about these wonderful birds.  The project will boost biodiversity in our borough & engage local communities with the conservation of these birds.

The swifts will be returning in April and May 2022, and so we hope to have the swift boxes erected by March, in plenty of time to help protect and conserve this iconic species for future generations.  Can you help by making a pledge to our fundraising effort?  We need to raise £10,000 in total, including £5000 from our followers which will be matched by Future Ealing.  Every little helps and you can pledge at www.spacehive.com/savingealingswifts.  If you are not able to contribute, there are other ways you can help, by offering your time to support some of our work by volunteering.

Thank you all for your ongoing support and for making Ealing such a great place for wildlife!

Heather from Calderglen on Ealing’s Harvest Mice

Heather Ryce releasing her captive bred harvest mice at Horsenden West meadows

“Conservation work involves the protection, preservation or restoration of nature and biodiversity, not a task one would immediately associate with Instagram or TikTok. However, more and more we are utilising social media platforms to share ideas and information, organise events and have conversations with one another regarding wildlife and the environment. It’s blending our very primal need to be one with nature with our newly evolved reliance on technology, and in most cases, it is working to the benefit of the natural world. 

In the case of releasing endangered captive-bred harvest mice back in Ealing we have Instagram Stories to thank. No, really. 

I have followed Dr Sean McCormack and Ealing Wildlife Group on social media for a while. I was inspired by the passion and innovation of both and drawn back each time on my phone by the community spirit and the sharing of wildlife photographs and information.

When Sean posted on his Instagram about a new project to return harvest mice back in a suitable habitat and monitor their population I paused my Netflix show, put my glass of red wine back on the coffee table and furiously began constructing my reply. I had to be involved. 

I work as an Animal Keeper and Education Officer at a small zoo in South Lanarkshire, Scotland. We care for a very successful breeding group of harvest mice and had been on the look out for a while for a project to introduce our mice back into the wild, as we were reaching maximum capacity in their enclosure. 

Some of the first Calderglen mice installed in EWG’s brand new captive breeding programme HQ

We had explored options in the past, but nothing seemed to work out or last. I wanted a project that Calderglen could fully get behind and believe in, and that gave our Scottish mice the best chance at surviving. 

After talks with Sean I knew the area chosen for their release and the people involved offered the harvest mice the best chance at restoring a wild population in Ealing. A species that hasn’t been recorded there since the late 1970s. It was time for that to change. 

After a couple of months of more conversations and planning with Sean the morning arrived for the long journey down to London. I plucked the fittest mice from the safety of their captivity, clinging unknowingly to their corkscrew hazel branch and silently wished each one good luck as I placed them into the travel box, awaiting a life of freedom only wild animals understand. 

It’s not lost on me the control humans have over non-human species and even though in my heart I knew I was doing the right thing for the conservation of harvest mice, looking at each individual twitching face, I also battled with doubt if it was what they would want. 

It may seem silly, after all how could a mouse possibly understand the concept of consent and the importance of its little life in the preservation of its entire species, but it certainly picked at my moral compass regardless. 

It’s why I take so much comfort in Ealing Wildlife Group’s project because out of the many that have been reviewed by Calderglen this one surpassed expectation. 

Heather Ryce at Horsenden Farm, ready to go release her precious charges into the wild

It was a lovely evening when I met with members and volunteers of Ealing Wildlife Group and I quickly felt I was with ‘my people’. Our enthusiasm and passion kept the chat flowing as the sun started to dip and the smiles and laughs just got wider and louder even after we stopped recording videos on our phones. Everyone was excited to be there, everyone wished for the success of the project, and everyone believed it was the right thing to do to give back to nature. 

Heather and EWG’s Caroline and Sean chat to passersby about the mice and reintroduction programme

We let Calderglen’s mice go in thickets of grass and flowers, with a small shelter and some food left behind for a short-term resource if they should need it. I watched one particular brown and white fuzzy ball dart immediately from the travel box and wind its way gracefully into the foliage. 

Heather, Sean and Caroline assess a likely release location for one group of mice

A bubble of emotion rose in my throat as I again wished it a silent good luck. As I uploaded the video to my Instagram with the caption ‘They’re free!’ and watched the mouse get lost behind stalks of green and fade from view, my doubts vanished. The harvest mice were home. “

The door to their soft release tank (with familiar food, water and shelter) is open, and they are free to be wild again…

New Harvest Mouse partnership with Battersea Children’s Zoo

Battersea Harvest Mice

We’re very excited to be partnering with Battersea Children’s Zoo and their sister zoo, New Forest Wildlife Park, both of which will be providing us with captive bred harvest mice to release in Ealing over the coming years. I recently visited Battersea and was astounded by their beautiful Harvest Mouse exhibit, which showcases just how busy (and adorable) these little mice are. Here’s what Head Keeper, Jamie Baker, has to say about the partnership:

“Battersea Park Children’s Zoo has always championed British native species. Alongside our conservation work with other BIAZA and EAZA facilities on European Endangered Species breeding programmes we have always worked to put our own native species at the forefront of our work. As one of most successful zoos working with the Scottish wildcat breeding programme, producing 5 kittens over the last couple of years, we also collaborate on reintroduction projects for native hedgehogs and of course, Eurasian harvest mice, which are increasingly threatened in Britain. 

Battersea Children’s Zoo Harvest Mouse enclosure


We currently have one of the largest harvest mouse exhibits in the country and actively breed mice at the zoo before transferring them to reintroduction projects up and down the country. Education is key in providing a future for our native species, so our dedicated harvest mouse barn is a great opportunity for our yearly 8500 school children to connect with these relatively unheard of creatures. 


We are excited to have struck a new partnership with Ealing Wildlife Group and can’t wait to shine a light on their amazing work to restore wild places in London and reintroduce native species. Our curator Jason and head keepers Jamie and Charlotte had the pleasure of welcoming Sean to the zoo recently to discuss our joint passion for harvest mouse conservation and we look forward to providing captive bred harvest mice to Ealing Wildlife Group’s upcoming release projects. Joining forces to rewild some amazing habitats in West London.”

The team at Battersea and New Forest are also keen to come help us survey for harvest mice to monitor how well the reintroduction project is going over the coming years. There will also be opportunities for volunteers to help with this important work. Exciting times!

We’ve recently kicked off our ‘Rewilding Ealing’ initiative with the reintroduction of locally extinct and nationally threatened species, the diminutive Harvest Mouse. Also known by its scientific name of Micromys minutus, or the ‘minute micro mouse’, it’s the UK and Europe’s smallest rodent, and the only one with a prehensile tail designed to cling to the finest of grass stalks and vegetation as it climbs.

Last year we outlined the aims, preliminary survey work and preparations for the project in a live webinar, a recording is available to watch here:

We were thrilled with the reaction to our crowdfunding campaign, helping us to raise funds to source mice in large numbers for release and also allowing us to buy equipment and housing for our very own captive breeding facility. We asked our community of wildlife fans to sponsor a mouse for £10 and reached our target within days. The crowdfunder, which is still open to donations to support our borough-wide conservation efforts, can be found here:

We’ve partnered with Calderglen Zoo in East Kilbride near Glasgow who has been breeding Harvest Mice, and a few weeks ago delivered our very first mice to be released as well as to form the foundation of our own captive breeding colony.

And since the initial release we’ve had quite a bit of interest and coverage including BBC London and Scotland news. Check out the release and see these amazing little rodents being set free into the wild after a potential absence of 30-40 years from our borough here:

Group reintroduces the threatened Harvest Mouse back to London!

Harvest Mice are set to be released in a new location in London by a local community group in Ealing, West London – bringing the rodents back to the area for the first time in decades.

Harvest Mice are Britain and Europe’s smallest rodents, and, in recent decades, these miniature mammals have undergone rapid declines due to changes in land management nationwide.  The mice live mainly in grassland areas and eat seeds, fruit and invertebrates and build their spherical nests high up in tall grasses.  

Reinstating the harvest mouse population is important for a number of reasons but, most significantly, their presence in the Ealing area can support the wider food chain and will be a welcome addition for Ealing’s growing populations of birds of prey including Barn Owls, Kestrels and Little Owls.

Local community group, Ealing Wildlife Group (EWG) are behind the project.  EWG is focused on bringing nature back to urban areas and have spearheaded a number of other successful projects in the area including driving the increase in bird of prey species nesting in the borough.  

In order to release the Harvest Mice, Ealing Wildlife Group (EWG) successfully crowdfunded their project to purchase hundreds of captive-bred mice from one of the UK’s leading rewilding experts and set up small breeding colonies of their own. The plan is to release the mice into the wild over the next couple of years.

Sean McCormack, Chair of local conservation community Ealing Wildlife Group (EWG), believes that communities and councils can work together to create suitable space for nature, and the Harvest Mice reintroduction project is just the latest in a long line of projects being spearheaded by EWG.  Dr McCormack said:

“After extensive surveying of likely locations in Ealing, we believe Harvest Mice are locally extinct here due to historic habitat loss and fragmentation.  Over the last few years however, there has been an effort to manage some of Ealing’s green spaces more sympathetically for nature.  What this has done has enabled several sites within the borough to now have habitats suited to the reintroduction of Harvest Mice.”

After holding a webinar with the local community to outline the details of the project, McCormack set up a crowdfunding page to help fund the reintroduction – asking funders to ‘sponsor’ a mouse for £10.  The money raised will go to buying mice from a responsible breeder, one who supplies many rewilding projects with rare and threatened native wildlife, plus equipment for setting up some small breeding colonies of their own – enabling EWG to continue releasing mice into the wild in Ealing over the next couple of years. 

EWG is also partnering with a number of conservation organisations already breeding Harvest Mice including Calderglen Zoo in East Kilbride near Glasgow, who have supplied the first cohort of mice to have been set free into the wild in Ealing.

EWG will also spend an extra £500 on Longworth live mammal traps, enabling the harmless monitoring of small mammal populations in Ealing.  This monitoring will ensure the habitat management continues to be successful and that populations of the harvest mice, as well as other small mammals such as voles and shrews, can continue to thrive for years to come.

Fundraising has been incredibly successful and the £2,500 target was hit within days of set up however, if you would like to contribute to this exciting urban rewilding project, you can find the Harvest Mice Reintroduction page here.

About EWG

EWG is an inclusive community of locals interested in nature and wildlife in the Borough of Ealing and beyond.  Set up in early 2016 by Sean McCormack, a vet and lifelong naturalist, the overall aim of the group is to build a community of like-minded individuals, who are passionate to learn more about nature and who see the value in actively conserving it.  Since 2016 it has grown steadily in membership and secured funding for several community environmental projects.  The main hub of activity and discussion remains the Facebook group, where members can truly appreciate the diversity of wildness on our doorstep through others’ observations and posts.

‘Help an Ealing Owl’ project update

Back in 2018 EWG and the Council ranger team collaborated on a fundraising bid to erect owl nest boxes all over Ealing for Barn, Little and Tawny Owls, the three most common species found in and around London. Barn Owls were our main target species, as we knew the other two were already breeding here in relatively good numbers. But the Barn Owl situation was less clear. We’d spotted and had sightings reported of them hunting in various areas, but no confirmed breeding.

So we managed to secure £2000 from Tesco Bags of Help to try to help them become established. We bought about 18 nest boxes of various designs to attract all three species and later in 2019 got to putting them up all across the Borough in likely locations. And with the parks team, we set about changing some of the local grassland management to encourage more biodiverse rough grassland habitat, mown on a 3-4 year rotation to encourage voles, mice and shrews. Basically boosting our owls’ and other predators’ food supply! You can see more about the early stages of the project here:

Our 2020 owl breeding season kicked off with a promising start as trail cameras placed on several of our boxes revealed that they were being visited by owls, including some Barn Owls. Unfortunately, the box where we confirmed Barn Owls as regular visitors in January and February fell victim to theft and disturbance later that season. Some men with a ladder were reported to us looking suspicious. and alas our trail camera containing all of our footage was gone. We had left it well alone after our last check in February so as not to disturb the owls if they were breeding. But when we went back to check in May/June the camera and the owls were nowhere to be seen. A hazard of leaving wildlife cameras out in any location, but especially in the urban environment. All was not lost however, as a pair of Kestrels moved in and raised young in the same box. Not a target species, but very welcome nonetheless.

We believe a Little Owl pair attempted to breed in one of our boxes in 2020 but couldn’t confirm if they successfully fledged. Anyway, the pandemic and lockdown restrictions prevented us getting out to monitor and check our nest box success rates for much of the breeding season, but this project was always going to be a long game of providing nest sites, changing habitat dynamics and boosting prey availability. We were patiently impatient that the 2021 season would be better and yield success.

Below is some footage of various owl species visiting, and even scrapping for access to our nest boxes. This tells us that with such competition and defense of boxes, that natural nest sites suitable for owls are in short supply. It makes sense as old trees with large cavities are few and far between in urban environments in particular where human health and safety is a genuine concern to be balanced alongside nature conservation.

2021 saw lots of owl action at various boxes, with all three species investigating. One particularly feisty Little Owl pair commandeered a large Barn Owl box for themselves, fighting off Barn Owls and Tawnys that came to inspect it for their own uses as you can see here:

We’ve been out recently with local licensed bird ringer Phil Belman to check on our nest boxes under license and ring any chicks we found for ongoing population monitoring. And though we are a little disappointed to say we’ve not confirmed any Barn Owls breeding (although there is still one inaccessible box and camera left to check), we have had a great year for Little Owls with a total of 10 chicks from three of our boxes. We tend not to check Tawny Owl boxes too closely as they have a reputation for being aggressive at the nest site. We did find one very early Tawny chick that fledged from a natural nest site locally, you can see him/her in this video:

Hopefully next year the possibly young and inexperienced Barn Owls who have been prospecting for nest sites at our boxes will move in and raise their own chicks. We’ve increased our number of boxes in 2020-21 too, with some of our members kindly making and donating nest boxes to the cause. Thanks Peter Nolan, David Gordon Davy and the Sullivans for making some great boxes for us free of charge. And here’s hoping 2022 is a bumper year for Ealing owls!

In the meantime, enjoy some photos of the adorable Little Owl chicks we ringed recently. Thanks to BTO licensed bird ringer Phil Belman for collaborating with us on this important part of the project to monitor our owl populations and how habitat management is affecting them over time.

Rewilding Ealing update: Harvest Mice are coming!

We have been busy behind the scenes scoping out the habitats, logistics and feasibility considerations for reintroducing Harvest Mice to Ealing. This tiny rodent species has declined significantly nationwide in recent decades, and we believe after much surveying in suitable habitats that it is locally extinct. For more context on Harvest Mice and the project you can watch our kick off meeting here:

https://www.youtube.com/watch?v=DNbY6TtgJnA&t=13s

As with any reintroduction project, there are ethical and practical procedures and guidelines to follow so as not to:

  • cause harm to the local ecosystem
  • cause welfare issues with the reintroduced species or others in the local environment
  • cause socio-economic harm or concerns
  • introduce disease into natural ecosystems
Harvest Mouse by Amy Lewis, The Wildlife Trusts

We have reviewed DEFRA’s newly released codes and guidance for reintroductions and other conservation translocations. And we feel we have satisfied the requirements as well as carried out the appropriate surveying and preparations needed to justify and carry out a successful reintroduction programme. We’ve also consulted with previous Harvest Mouse reintroduction project managers and rewilding experts who advised us that we have the suitable, sustainable and connected habitat to bring back this lost species again. More info on the codes and guidance can be found here:

https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/987068/reintroductions-conservation-translocations-code-and-guidance-england.pdf

So what’s next and where are our mice coming from? Well, we’ve teamed up with a zoo and country park in Scotland who maintain a large colony of harvest mice and want to collaborate with us on an in-situ reintroduction and conservation project for the species in their natural habitat. We’re also working with renowned rewilding advocate and expert, Derek Gow and his team, who are supplying us with captive bred mice for mass release and to start our own ongoing captive breeding programme.

And we cannot thank you, our supporters, enough for donating to fund the project by sponsoring a mouse (or many mice in some cases!). It’s a project which has obviously captured the public imagination, and it has also attracted some media attention (watch this space!). We hope to start releasing mice as early as July and September this year, and hope to have some of you along to see ‘your’ mice return to the wild. The crowdfunding was a great success, and is still open for donation to support ongoing costs of the project if you wish to sponsor a mouse for just £10.

Costons Lane Nature Reserve Update

Where we were in 2020, where we are now, and where we are going in 2021

Male Emperor Dragonfly

It’s been awhile and circumstances have slowed everything down but things are still moving forward at Costons Lane!

The weather and Thames Water have delayed the pond building until we get the go ahead from TW and it dries out a bit, but we have been working on other aspects of the project! The contractor has lifted the gate (so it opens now!) and will be building the platform for our building and the paths in the front half. Once this work is complete and restrictions lift, we can have volunteer days again! Our first task will be create the wildlife garden. And once the platform is complete we can order our beautiful green roofed recycled shipping container and finally give Ealing wildlife Group a home of its own!

Common Carder Bumblebee and a Bramble blossom

Of course the first priority of a nature reserve is to provide a place for nature to thrive and CLNR is no different. We had a bioblitz last summer, the first of many, to see what kind of plants and animals call it home. As expected most of what we found were insects and arachnids which is very good as the UK is catastrophically losing insect life! We had a few ladybirds, several species of tiny parasitic wasps, two kinds of grasshopper, leafhoppers, dock bugs, blue flea beetles, dragonflies, many different butterflies, bumblebees, honey bees, several spiders we don’t know what they are yet and a few wasp spiders which are always exciting! You can see the full gallery of critters below, the ones we know are named, if you think you can identify any of the others or think we may have got it wrong leave a comment below!

Wood Pigeon in a nest

As for birds we saw and heard robins, starlings, house sparrows, wood pigeons, and a red kite and sparrowhawk over head! On different occasions we have also heard wrens, green finches, and black caps as well! No amphibians or reptiles yet, but creating the pond should help the amphibians and of course we plan on building habitat for slow worms and if we are lucky maybe even grass snakes! The mammals we found were grey squirrels (of course,) a curious fox, and a few pipistrelle and soprano pipistrelle bats. We were expecting more bats but again the pond will create food and should attract more, most we saw seemed to be on their way to the river where food is plentiful.

Ranger Jon and some of our volunteers

Throughout the summer and early autumn we had several volunteer days, while it was still allowed and safe to do so. The first one was the biggest, with 30 volunteers and the help of the Ealing Park Rangers we moved enormous amount of rubbish out to the entrance to be picked up later! The area was originally an allotment site (abandoned 20 years ago because of the constant flooding) so much of the rubbish was bits and pieces of old allotment detritus. Unfortunately, it was also used as a fly tip so we found toilets, shopping trolleys, old footballs, shoes, batteries, you name it! Park rangers Jon and James cleared a path around the site with a giant mowing machine and later it will properly mulched. Our second two volunteer days were mostly clearing brambles from the area we plan to turn into a meadow to replace the meadow that will be lost when we build the pond. We still found and moved a tonne of rubbish we even found a bathtub! Then the lockdowns came and the weather turned and volunteering stopped for the winter.

Ranger James carving out the path

So where do we go from here? Anticipating the lockdown easing up in the spring, we will continue to have volunteer days, starting with the wildlife garden. And also exciting news, we have got two shipments of free trees from I Dig and the Woodland trust, so we will have to plan a planting scheme and get planting them out! Then working around the heavy works of pond building and path laying, we will build the bird hides and the pond dipping platform. I plan on setting up a spring bioblitz, as at Boles meadow I’d like to have a bioblitz in every season. After the large projects are complete, it will be different tasks, building and installing bird and bat boxes, different feeding stations, increasing the diversity of plants and micro habitats, and seeing how we could increase our connectivity to other green sites in the area. Later as the building is installed, we hope to build a deck around it to give us more space to teach, and have community events.

So that’s about it, progress is slower than we would like but not too bad considering the circumstances. As always, if you would like to volunteer, pop us am email at hello@ealingwildlifegroup.com and put volunteer in the subject heading and let us know what you would like to do. It may be a while until you hear anything back because of lockdown but hold tight and rest assured your help is very much wanted and appreciated! Hope to see you all in the spring!
