Type
This site is designated due to its biological qualities. SSSIs in Wales have been notified for a total of 142 different animal species and 191 different plant species.
The pale dog violet (Viola lactea) is particularly dependent on the heathland whilst the pillwort, slender centaury and chamomile thrive on winter-wet disturbed ground near and on paths and tracks. Floating water plants need areas of open water at least ankle-deep in summer and without too much organic matter. Natural Resources Wales attempts to encourage these conditions.
