calcicolous

The plant has difficulty growing in acidic soil (it is calcicolous).

In total, 14 calcicolous grassland communities have been identified.

All but two of the calcicolous grassland communities fall into two broad groups:

There, he worked on plant uptake of ions, especially iron, nitrogen fixation and calcicolous plants.

Yanal Bog is a calcicolous lowland mire.

The surface of the waste has since weathered down to calcium carbonate and calcicolous vegetation has colonised the site.

Open, species rich, calcicolous grassland.

Chondrina clienta feeds on calcicolous lichens.

Of the upland group of calcicolous grasslands, it is the only one with a short sward associated with heavy grazing.

This article gives an overview of the calcicolous grassland communities in the British National Vegetation Classification system.

Magnesian limestone grassland supports an assemblage of calcicolous plants adapted to growing in thin soils with a short sward.

Calcicolous grasslands (14 communities, prefixed "CG")

It is one of four communities of rank, tussocky grassland associated with low levels of grazing, within the lowland calcicolous grassland group.

NVC community CG4 (Brachypodium pinnatum grassland) is one of the calcicolous grassland communities in the British National Vegetation Classification system.

It is classified under the British NVC community CG2, i.e. Festuca ovina - Avenula pratensis grassland, one of the calcicolous grassland communities.

The site has unimproved calcicolous grassland, some of which is mixed with dwarf-shrub, mosaics of calcicolous grassland and scrub and woodland.

It is one of three short-sward communities associated with heavy grazing, within the lowland calcicolous grassland group, and is regarded as the eastern counterpart of "typical" chalk grassland (community CG2).

The waste on both sites has since weathered-down to calcium carbonate and has provided an ideal environment for a number of nationally rare calcicolous plants, unique in what is predominately an area of acidic soil.

Yanal Bog, a calcicolous mire near Sandford is designated for its plant communities, within which grow Black Bog-rush (Schoenus nigricans) and Blunt-flowered Rush (Juncus subnodulosus), two plant species rare in southwest England.

The calcifugous grasslands and montane communities of the NVC were described in Volume 3 of British Plant Communities, first published in 1992, along with the mesotrophic grassland communities and the calcicolous grassland communities.
