What People can do The pollution, loss and alteration of our wetland habitats is a massive threat to this species and the animals it preys upon. Working with farmers and landowners to ensure wildlife-friendly practices, The Wildlife Trusts are working towards a Living Landscape: a network of habitats and wildlife corridors across town and country, which are good for both wildlife and people. You can support this greener future by joining your local Wildlife Trust. Did you know? The Water Shrew is quite unusual amongst mammals as it has a poisonous bite.
