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.

Bryum valparaisense



Range & Status

(syn. B. pyriferum Crundw. & H.Whitehouse). Collected in the Isles of Scilly by the late

R.A. Finch in 2005 and identified by C.D. Preston (Preston & Finch, 2006). This remains the only British locality for a species that is likely to be an accidental introduction. It is otherwise known in Europe by a few records from S. Portugal, S. Spain and the Canary Islands, with a wider range in N. Africa (Libya, Sudan) and N. and S. America.

Regional Distribution

Known only from two small fields on St. Agnes.

Habitat & Ecology

Found only on acidic, sandy soil in traditionally managed flower fields.

Threats

Abandonment of the flower fields or changes to the traditional style of management (see Preston & Finch, 2006) may pose threats.

Conservation

None.
