Danthonia decumbens Heath-grass

A distinctive, densely-tufted perennial grass with narrowly ovate spikelets. It prefers infertile, acidic soils in grasslands and heathlands, including the slightly acidic, leached soils along the south Gower coast. It is also found in calcareous grasslands but it is rather intolerant of nutrient enrichment and is outcompeted by other species like Common Bent (Agrostis capillaris) under those conditions. It is frequent in West Glamorgan, particularly in Gower, but more scattered in Neath Port Talbot where it has been lost from suitable, infertile upland pastures which have been improved or planted with conifers.
