A Boreo-arctic Montane species, on the 1980, R.Davies (Wigston et al. 1981); in three places, edge of its range in Devon. Mainly restricted to Dartmoor, locally dominant over several square metres where it has been recorded on 31 tors since 2000, amongst small Molinia caerulea tussocks at principally on ledges and amongst clitter, with a few SX578596, 1994, R.E.N.Smith ; 30 colonies varying substantial populations in wet heath by small streams. from a few plants to an almost continuous patch Individual plants are occasionally found on heath or measuring 32 x 40 m in two clay pits and by two blanket peat remote from any of the bigger populations.

Old china clay workings at Cadover Bridge, once common there over an area of about 250 square metres at SX556648, the population had declined substantially between 1986 and 2003 as the site dried out, P.D.Pullen .

SX67 Four plants on old tin workings on the fringe of Fox Tor Mire at Whiteworks, SX618709, 1971, D.L.Wigston . This population suffered during the 1976 drought with only one plant still surviving by 1979 (Wigston 1979). Not seen since. l Lycopodiella inundata (L.) Holub Marsh Clubmoss Very rare. Endangered on the British Red List. Native. In damp peat on heaths and moors. The only recent records are from southwest Dartmoor near Cadover Bridge and at Smallhanger Waste, Crownhill Down, where it occurs in some quantity in disused china clay workings at both sites. Crownhill Down is now under threat from tungsten mining. There are earlier records from the Bovey Tracey area, where the sites were destroyed by mid 20 th century housing developments and ball clay mining, from the East Devon Commons where it was last reported from a number of sites in 1963, and from the Blackdown Hills where it persisted at Maiden Down until 1985. In North Devon the plant was collected twice during the 19 th century near Trentishoe but has not been seen since.
