Definition of favourable conservation status for calaminarian grassland.
This paper sets out Natural England's view on Favourable Conservation Status (FCS) for calaminarian grassland (generally referred to as 'grassland on soils rich in heavy metals') in England. Favourable conservation status is defined in terms of three parameters: natural range and distribution, area, and structure and function attributes. The paper provides the summary definition of favourable conservation status in England, covers contextual information, units used and describes the evidence considered when defining favourable conservation status for each of the three parameters. It sets out the conclusions on favourable values for each of the three parameters.
