I've just started reading Neolithic Britain and Ireland by Caroline Malone.

In it she has a table showing chronology and features:

4000-3200BC - Wooded Landscape, causewayed enclosures, cursus monuments.

3200-2800BC - Semi Cleared landscapes, Enclosures, henges, avenues and alignments.

2800-2000 BC - Open Landscape, elaborate henges and stone circles, stone rows, avenues and pit alignments.
