primary forest
1. A climax forest comprising primary or climax species, i.e. a forest that either has not been severely disturbed or has fully recovered from disturbance by a secondary succession.

2. A forest occupying a site that has been continuously forested (in Britain since the last ice advance) even though it may have been clear-felled, provided that the clear-felling does not break the forest continuity (i.e. the forest regenerated or was replanted).
