The economic cost of this damage to the UK is estimated at over £50 million per year for commercial forestry alone. The real cost of damage is many times this figure, as the majority of forestry in the UK is not commercial, and damage to gardens, private woodlands and public parks is usually not quantified.

The recently published report also estimated that the total cost to the British economy of invasive non native species was £1.8 billion every year.

Grey squirrels are identified as having a wide range of impacts from reduction in wood production to an adverse effect on biodiversity. But more and more damage is occurring in and around our towns and cities.
