Small mammals are an important group of animals in our country. They are a key component of our ecology. They feed on vegetation, seeds, fruits, nuts (mice and voles) and invertebrates (shrews), and are in turn, food for weasel, stoats and birds of prey like Kestrels and Owls.

Their presence and abundance informs about the state of our local wildlife resource. They are also in some cases habitat dependant. Wood Mice are also called Field Mice as they frequent both habitats. Field Voles, unsurprisingly favour fields and bank voles and woodland edgers.

Optimising for small mammals ideally requires a varied mix of habitats in the correct proportion to support the greatest number of species and the quality of these habitats will determine to an extent the abundances of each species. They are basically very good wildllife 'health' thermometers.
