Habitats

The following photos are examples of habitats defined using National Vegetation Classification (NVC). As examples they cannot be used as a substitute for the official guides to classify vegetation elsewhere. I hope however they are useful illustrations of the the vegetation that can be found in some NVC comunities.

I highly recommend that anyone interested in pursuing this topic consults the following books:

British Plant Communities (Volumes 1-5)

Plants and Habitats

Abbreviations

CG = Calcarious grassland vegetation (typically found on alkaline soils)
H = Heath vegetation
M = Mire vegetation
MG = Mesotrophic grassland vegetation (typically found on PH neutral soils)
U = Upland vegetation (typically found on acidic soils and dominated by grasses or sedges)
S = Swamp vegetation (emergent from standing water)

Click the photos to enlarge them. Many have notes on to help with their interpretation.
