There are reports this season from respected arborists, that the advance of Ash dieback disease is breath taking across Yorkshire and Lancs/Cumbria.
I travelled over to Gisburn a few days ago and the majority of Ash trees, both young and mature, had severe thinning and dieback, with many looking near death. Plenty of evidence also on mature trees in Calderdale.
In the adjacent limestone areas where virtually every other tree is an Ash, it will have devastating effects.
Plenty of 'woodlands' being planted but no one is replacing the landscape trees which we all love and make the land what it is.
