My large Ash Tree has developed large white spotted areas on its bark fairly high up two of the three trunks.What could be causing this? Does not effect growth or leaves these are both as healthy as they have always been for the last13 yrs the tree is much older than this

Google Ash die back......
its a fungal disease that is endangering our ash trees, forestry commission and woodland trust have more info.
I do hope its not that as sadly its usually fatal.

It won't be ash die back - Chalara fraxinus causes simple die back initially, with a dark, diamond pattern on affected branches. If you hadn't said 'large' white areas, I'd have said it was scale infestation - these produce white fluff, though I guess if there's lots concentrated in an area, from a distance, it might look like a single large area. Google "scale insects on ash tree trunk UK" for images.
