Flora of Ashdown Forest - Botanical Society of the British Isles

15The number of different visits to squares (mean 8 visits per square), and the number of differentbotanists who visited each square (mean 6,5 botanists per square) are shown in Figures 2 and 3respectively.The hours spent recording are shown in Figure 4; we have achieved a reasonably even coverage(mean 11 hours per square). With hindsight the squares 48.32, 49.32 and 49.33, which were recordedas part of tetrad 43W for the BSBI Monitoring Scheme, should have been re-recorded during 1993-1995as they have had many extra hours of recording above our target of 10 hours.Figure 4.

The habitatsrecorded are shown on the following maps, with open circles where they are present but unrecorded(e.g. on private land). The maps show we have been reasonably successful in recording the knownhabitats in the area; where we have failed has largely been on private land (to which we have notalways asked for access).Ancient woodland Semi-natural woodland Plantation
