T182 Atlantic acidophilous Fagus forests
Description
Acidophilous analogue of T172, whose understorey lacks the most ostensibly calcicolous species (especially those associated, like Carex caudata, with abrupt calcareous beechwoods) and is dominated by calcifuges like Blechnum spicant and Luzula sylvatica.
