A new citizen science project aimed at improving understanding of small mammals in Guernsey and Herm has been launched by the Guernsey Nature Commission.
Small land-dwelling mammals play an important role in maintaining the natural balance of the islands’ ecosystems. They act as a food source for birds of prey such as owls, buzzards and peregrines, help control pest populations, and contribute to processes such as seed dispersal and soil health.
However, the State of Nature 2024 report highlighted that there are fewer small mammals in Guernsey and Herm than in the UK. A previous island-wide survey carried out in 2018 provided a baseline, but no full follow-up survey has been undertaken since. As a result, there is currently no clear picture of whether populations are stable, increasing or declining.
Garden Paws has been developed to help address this gap by enabling islanders to contribute data from their own gardens and local green spaces. The project uses simple ‘footprint tunnels’, which allow animals to leave prints on paper as they pass through, providing a non-invasive way to identify which species are present.
Participants can use a footprint identification guide to help recognise different species, based on factors such as size, shape, number of toes and movement patterns. Results can then be shared with the Guernsey Nature Commission, where they can be verified and used to support ongoing monitoring and conservation work.
The Commission said the data collected through the project will help build a clearer understanding of small mammal populations across the islands, filling gaps left by the lack of regular surveys and helping to inform future conservation efforts.
The project is open to anyone, regardless of experience, and is designed to be accessible for families, schools and individuals. By encouraging wider participation, Garden Paws aims to both gather useful data and strengthen connections between the community and the natural environment.
