[2] Culm grassland is found in poorly drained lowland areas of acidic soil where there is high rainfall.

The vegetation includes abundant purple moor grass and sharp-flowered rush.

The Trust endeavours to protect, re-establish and link together isolated sites of culm grassland.

In the reserve there is light grazing by cattle and deer; the low-intensity land management, little changed from prehistoric times, allows a wide diversity of plant species.

The plants support many species of butterflies, such as small pearl-bordered fritillary, marbled white and dingy skipper; birds including curlew, snipe and reed bunting may be found.
