The history
Before the Lancashire Wildlife Trust purchased Brockholes, when it was a sand and gravel quarry, trees were planted as a screen to block out sound; there was no thought given to the species of tree or the longevity of the woodland.
Planting one species in excess is not good for biodiversity and unfortunately, most of the trees planted in certain woodland areas of Brockholes were Ash.
What is Ash dieback?
We now have the issue of Ash dieback to deal with; a fungal disease spread through European Ash trees and is thought to have caused the death of around 90% of the Ash trees in the UK.
