Across the country the red squirrel
population is in drastic decline, and the main reason has been the growth and spread of the grey squirrel. Grey squirrels
out-compete the reds for food and shelter, and spread the squirrel-pox virus which they are immune to, but which kills the
reds. See Squirrel Info for more.
The number of grey squirrels in
Northumberland has rocketed in recent years. The invasion threatens the red squirrels in Northumberland with extinction within 3
years. In addition the red squirrels in the largest preserve in the country at
Kielder Forest will also be under
threat. For the latest on the current situation, view our latest News and Map of Northumberland.
An invasion by grey squirrels into
Northumberland will also have devastating effects on all wildlife throughout the area. A study by the charity SongBird Survival
(July 2006) revealed a decline in the numbers of young produced by Blackbirds and Whitethroats where grey squirrels have been introduced. Grey
squirrels also destroy Beech and Oak trees by stripping the bark of them.
