Red and Gray Squirrel Distributions Mapped
Mar 7, 2023
The red squirrel (Sciurus vulgaris) is a species of tree squirrel typical throughout Europe and Asia. The red squirrel is an arboreal, mainly herbivorous rodent.
In the British Isles, the species’ specimens have declined drastically in recent years. This decrease is associated with the introduction by humans of the grey squirrel (Sciurus carolinensis) from North America.
The first documented introduction of grey squirrels in continental Europe was in 1948, and they were brought to Stupinigi (Italy), where there is still a rising population.
