Bristle Bent on Cefn Bryn

The National Vegetation Classifcation (NVC) community U3 Agrostis curtisii grassland is typically dominated by the dense tussocks of Bristle bent (Agrostis curtisii), as shown below in the photograph taken on Cefn Bryn yesterday. This is an acid grassland species that thrives where there is frequent burning and heavy grazing and Gower represents the northern limit of its European range. The walk to Arthur's Stone (SS491904) is a good spot to see this very distinctive, but easily overlooked community.
