Volunteers needed to record garden wildlife for nationwide ‘Living with Mammals’ survey

This spring, volunteers across the UK are being asked to record sightings of mammals spotted in their gardens, local parks and other green spaces, in a bid to understand our changing environment better and encourage urban wildlife to flourish.

 The annual ‘Living with Mammals’ survey is run by wildlife charity People’s Trust for Endangered Species (PTES). It’s a nationwide survey that records how wild mammals – from badgers and bats to water voles and weasels – are faring in all corners of the country. Importantly, it also helps to identify areas where conservation action is most needed.

 Urban green spaces, and the biodiversity they support, are important to people and wildlife alike. The citizen science project is building a long-term picture of the ‘green health’ of these spaces, which can be a refuge from pressures in the wider countryside for many species, including hedgehogs.

 Volunteers simply need to record sightings of any wild mammal (or the signs they leave behind such as footprints or droppings) each week online (ptes.org/lwm). Sightings could be from a garden, however big or small, allotment, or public green space such as parks, playing fields and cemeteries. PTES offers free advice online to help volunteers identify species and recognise tell-tale signs, so anyone can take part – you don’t need to be a wildlife expert! And even if it’s just a grey squirrel that visits, every record is valuable and part of the bigger picture.

David Wembridge, Mammal Surveys Coordinator at PTES explains: ‘’Recording which mammals you see is vital to conservation. Living with Mammals has been running for over 20 years and with the long-term dataset we have so far, we’re building a nationwide picture showing where different species are living and sadly where some are no longer living. We’re lucky to have so many volunteers that take part every year, but more help is always needed. If you can spare some time each week, we hope you’ll join us in trying to help save as many of our much-loved species as possible.”

 In previous years PTES has had sightings of some of the UK’s more well-known mammals such as hedgehogs, foxes, grey squirrels and bats, but a few less-common mammals such as otters and pine martens have also been recorded.
