Ash dieback shows first in the crown. Thinning leaves. Dead tips. Whole branches sat bare while everything else is coming into leaf. Check the bark where branches meet the trunk for diamond-shaped lesions. Dark staining at the base is another giveaway. Once it takes hold the wood goes brittle fast. Big worry if you've got one near a path, drive or boundary. We're seeing it right across Wigan on mature ash. Worst on the wetter clay ground. If yours looks off, Wigan Tree Services will pop out for a free, no-obligation inspection.
