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.

Herniaria ciliolata - Ciliate Rupturewort



Range & Status

Native. This species is subdivided into subsp. ciliolata and subsp. subciliata (Stace, 1997). The latter is endemic to Jersey, but the former is endemic to The Lizard and to Guernsey and Alderney in the Channel Islands.

Regional Distribution

In Cornwall it is confined to The Lizard and has been recorded here in 35 1km squares. It is to be found in six of the SSSI on The Lizard, and extends along nearly the whole length of its coastline, with one inland outlier.

Habitat & Ecology

Shallow soil in cliff-top grassland, on maritime sands and rocks, on walls and coastal footpaths and inland in some areas along the west coast of The Lizard (Frost, 1964).

Threats

As it is favoured by the appearance of new coastal footpaths, regardless of geology and any environmental extremes, waterlogging in winter, drought in summer, it is apparently not threatened in any way.

Conservation

Much of the southern part of The Lizard is protected by Natural England and the National Trust.
