Grey Squirrels In Ireland Stock Image

The grey squirrel (Sciurus carolinensis) is an invasive species in Ireland. Originally introduced from North America in the 19th century, it has spread rapidly and has had significant ecological impacts, particularly on the native red squirrel (Sciurus vulgaris). Grey squirrels are larger and more adaptable than red squirrels, which has contributed to the decline of the latter in many areas.
