Managing Fraxinus excelsior (Ash dieback) in woodlands

BALI's Technical Officer (Policy & Research), Owen Baker, reports on Fraxinus excelsior. As the nights draw in and temperatures gradually fall, I’m sure you’re noticing the gradual change in leaf colour as the long, hot summer steps aside for autumn. Whilst the season is still in its infancy, as I type this, some of the trees are beginning to show signs of the new season.  Of course, some are already partially defoliated – a symptom of the stress many were under.   

An important part of both natural and managed landscapes, Ash trees can be relied on for a great display of autumn colour.  From vibrant yellows and oranges to red and deep scarlet, they are an intrinsic part of the countryside and complement other native trees. If, like me, you have spent time on the road or rail network recently, you’ll have enjoyed the blur of colour as you look out the window.
