When undertaking an appropriate assessment of impacts at a site, all features of European importance (both primary and non-primary) need to be considered.
Annex I habitats that are a primary reason for selection of this site
|6130 Calaminarian grasslands of the Violetalia calaminariae|
|Ox Close is a large site representing Calaminarian grassland in the central Pennines. The site is unusual in that it encompasses the three main situations in which this habitat occurs in the UK, including near-natural forms on cliffs and scars, old spoil-heaps from past lead-mining, and metal-enriched river alluvium. This site supports a rich metallophyte flora with substantial populations of five species of higher plant metallophytes: thrift Armeria maritima, moonwort Botrychium lunaria, Pyrenean scurvygrass Cochlearia pyrenaica, spring sandwort Minuartia verna and alpine penny-cress Thlaspi caerulescens. The site shows the full succession from open sparsely-vegetated spoil to closed turf. Transitions from Calaminarian grassland to 6210 semi-natural dry grassland and flushes also occur.|
