Gorse This large neglected common comprises extensive tracts of acidic scrub, with acidic grassland confined to pathways and tracks where the dominant vegetation is excluded by trampling. Secondary woodland occurs on sloping land at the southern periphery, and a hawthorn (Crataegus monogyna) hedgerow to the north.
Yorkshire fog (Holkus lanatus) currently forming the ground flora. Dense stands of rosebay willowherb and creeping thistle (Cirsium arvense) form scattered patches on the western side where regeneration after previous burning has not been successful.

Unimproved acidic grassland is now very limited in area. Common bent (Agrostis capillaris). wavy hair-grass (Deschampsia flexuosa). sweet vernal-grass (Anthoxanthum odoratum) and Yorkshire fog (Holcus lanatus) are dominant with only occasional herbaceous species such as sheep’s sorrel, heath bedstraw (Galium saxatile) yarrow (Achillea millefolium) and harebell (Campanula rotundifolia) present. Drier or more heavily rabbit grazed patches also include early hair-grass (Aira praecox) and bryophytes. while nettles (Urttica dioica) and hogweed (Heracleum sphondylium) are present in a ranker sward towards the peripheries.

Rosebay willowherb

Occasional areas of neutral to basic grassland are also present, presumably where underlying chalk approaches the surface. Here the sward includes yellow oat-grass (Trisetum flavescens). lady’s bedstraw (Galium verum) and mouse-ear hawkweed (Pilosella officinarum).

On a steeply sloping area along the southern boundary secondary woodland comprising sycamore (Acer pseudoplatannus), ash (Fraxinus excelsior), silver birch (Betula pendula) and elm (Ulmus sp.) has developed. Similar woodland is also found between the double hawthorn hedge along the northern boundary, with the addition of beech (Fagus svlvatica) and lime (Tilia sp.).

A large, disturbed sand pit is present in the south and this supports a sparse cover of common stork’s-bill (Erodium cicutarium) and buck’s-horn plantain (Plantago coronopus), with taller herbs occurring in less disturbed areas, including viper’s bugloss (Echium vulgare) and white campion (Silene alba).
