England Squirrel Population

The grey squirrel population in England is estimated to be around 2.5 million, with the population increasing by around 5% each year. Grey squirrels are native to North America and were introduced to England in the 1870s. They have since become the dominant squirrel species in England, displacing the native red squirrel. Red squirrels are now only found in a few isolated pockets of England, with the population estimated to be around 140,000. The decline of the red squirrel is due to a number of factors, including habitat loss, competition from grey squirrels, and disease.

England Squirrel Conservation

Red squirrels face competition and displacement from grey squirrels, which are not native to the UK. The Grey Squirrel Initiative, launched in 2014, aims to conserve red squirrel populations by controlling grey squirrel numbers through targeted killing and habitat management. The initiative has seen some success in reducing grey squirrel populations and supporting red squirrel recovery in certain areas. However, ongoing efforts are needed to maintain these gains and ensure the long-term conservation of red squirrels in England.

England Squirrel Habitats

England is home to two species of squirrels: the red squirrel and the grey squirrel. Each species has its own preferred habitat type.

Red Squirrels: Red squirrels are native to England and prefer coniferous forests with mixed broadleaf trees. They require large, uninterrupted areas of habitat with a good supply of cones, their primary food source. Red squirrels are arboreal and spend most of their time in trees, building dreys (nests) in the forks of branches.

Grey Squirrels: Grey squirrels were introduced to England from North America in the 19th century. They are highly adaptable and can thrive in a variety of habitats, including broadleaf forests, woodlands, parks, and urban areas. Grey squirrels are less reliant on trees for food than red squirrels, as they also consume acorns, nuts, fruits, and buds. They will build dreys in trees but also utilize other sheltered structures, such as bird boxes or loft spaces.
