Much of of the heathland has been lost to oak-birch woodland and open areas have been invaded by birch and gorse.
The dry lowland heathland was once widespread on the heath. Varieties include:
Wet heathland occurs where drainage is limited and is dominated by cross-leaved heath, ling and purple moor-grass. Rushes and sedges also occur, as well as bog-moss and vascular plant species such as round-leaved sundew.
Early records have shown that the site had richer flora than it does today. A total of 311 species have been recorded since Gibson's Flora of 1862. This includes:
21 tree and shrub species
11 rush species
17 sedges and relatives
9 fern species
The ponds and ditches also support several local species and aquatic flora has shown some declining. Recent work by some of the volunteers to re-establish some of the stream, may help to increase some of this flora.
The two ponds support aquatic flora, including pondweeds and duckweed, with rushes. There are also invasive species including floating pennywort and New Zealand pygmyweed. The ponds are breeding sites for a range of dragonflies and damselflies.
