Native plants (N) are those that are native in Middlesex; Introduced natives (I) are those that are native elsewhere in England, but introduced in Middlesex; Archaeophytes (Arc) are ancient alien plants known to have been introduced before 1500 AD; and Neophytes (Neo) are more recent aliens, introduced after 1500 AD.


Three visits were made to the Wood - on May 1st, July 12th and August 11th. The visits lasted three hours on each occasion, giving a total of nine hours recording. Care was taken to visit all parts of the Wood on each visit.
