Description

Grey squirrels were introduced to Britain in the late 1800s, and their adaptability has allowed them to successfully populate much of the country. They are now a common wildlife species in urban areas and mixed woodland.

Habitat

To breed, grey squirrels need a safe and secure site to build their nest, often called a drey, where they can escape predators, bear and raise their young, sleep overnight and escape inclement weather. Usually the nest is constructed in a suitable tree, but other sites can be used.

Threats

When squirrels enter a loft space, they can cause structural damage by tearing up loft insulation for bedding, chewing timbers, pipework and stored items, and posing a fire hazard by stripping insulation from electrical wiring. They may also be noisy, and if they drown in uncovered waterstorage tanks, may contaminate the water supply. Problems in the garden are more annoying than dangerous.
