The ash trees in Colinton Dell are blooming just now
Wood sorrel is one of the plants that indicates ancient woodland, again showing that Colinton Dell has been woodland at least since 1750. This doesn't mean of course that all the trees are that old! In fact very few of the individual trees are likely to be that old. Colinton Dell was for many years a place of great industry as there used to be several paper mills along the Water of Leith. Most of these have become entirely derelict and many are now woodland again.
