When Brockholes 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. Unfortunately, most of the trees planted in certain woodland areas of Brockholes were Ash, and we now have the issue of Ash dieback to deal with.
What is Ash dieback?
Ash dieback is a fungal disease which originated in Asia and is spread through European Ash trees. It first appreared in the UK in 2012 and it throught to have caused the death of between 80% and 90% of the Ash trees in this country.
