Rock habitats are identified as a key habitat for conservation in the Guidelines for the Selection of Wildlife Sites in South Wales, and also in many of the LBAPs for the south Wales region, although not currently that for Blaenau Gwent county borough. These habitats may include natural and quarried exposures, and may support a range of plant species considered local or rare in the region. However, the open rock habitats within the site appear to support comparatively undifferentiated communities similar to those recorded in the nearby acid grassland and heathland habitats.
