A level, low-lying, surface at a mature stage of geomorphological evolution, which is part of a very old fully vegetated coastal sand-dune system and is normally marshy in winter.
A base of blown sand which has a significant percentage of shell-derived materials and a narrow range of grain sizes.
Lime-rich soils with a pH value normally greater than 7.0.
A sandy grassland-type vegetation with long dune grasses and other early dune species having been eliminated.
Evidence of a history of anthropic interference including heavy grazing (especially rabbits, sheep, and cattle), rotational cultivation and, in places, artificial drainage.
A moist, cool location...
