What is bad about the grey squirrel?

Answer 1

Grey squirrels are often considered a nuisance because they can cause significant damage to trees and gardens, as they strip bark and consume a variety of plants. They also compete with native species, particularly the red squirrel, for resources, contributing to the decline of the latter due to disease transmission and habitat competition. Additionally, their adaptability to urban environments can lead to increased human-wildlife conflicts, such as raiding bird feeders and nesting in attics.
