Cornish Red Data (2009)

The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.

Chordeuma sylvestre

Range & Status

Status: Insufficiently known. Can not be distinguished unless mature males are present. Recorded from only two 10km squares in Cornwall and from one Scottish site, it has been collected from woodland, waste ground and maritime habitats. Regarded as a central European species, it occurs in France at least as far as Normandy so the Cornish populations may be regarded as a natural extension of its range (Kime, 2001 quoted in Lee, 2006). It can be distinguished from the much more widespread C. proximum only when mature males are available (generally winter-spring).
