Controlling grey squirrel damage to woodlands

 

The grey squirrel (Sciurus carolinensis) was introduced from North America in the nineteenth century. It is widely established and many people value its presence in urban parks and gardens. However, grey squirrels have displaced, our native red squirrel (Sciurus vulgaris) throughout  much of England, Wales and central Scotland  and threaten its continued survival. In addition, grey squirrels strip the  bark from trees,  particularly broadleaved species, which can lead to degrade and tree death.

While it is neither practical nor desirable to completely eradicate grey squirrels, targeted control to protect valuable and vulnerable trees is often necessary.

Note - using warfarin: Following a recent review by the European Commission, continued use of warfarin for controlling grey squirrels after April 2007 will be on condition that only pre-prepared products or baits are marketed rather than concentrates.
