Oak (Quercus petraea) predominates the higher slopes with creeping soft-grass (Holcus mollis), false brome (Brachypodium sylvaticum), wood sorrel (Oxalis acetosella) and broad buckler-fern (Dryopteris dilatata); and on very acid soil beneath oaks, great wood-rush (Luzula sylvatica), bilberry (Vaccinium myrtillus) and common cow-wheat (Melampyrum pratense) are found.

[2] Ash (Fraxinus excelsior) is found site-wide, together with occurrences of downy birch (Betula pubescens), bird cherry (Prunus padus), yew (Taxus baccata) and alder (Alnus glutinosa).

Shrubs found in the woods include hazel (Corylus avellana), holly (Ilex aquifolium) and hawthorn (Crataegus monogyna).

By contrast, wet flushes on the site support giant fescue (Festuca gigantea), tufted hair-grass (Deschampsia cespitosa), bugle (Ajuga reptans), yellow pimpernel (Lysimachia nemorum) and meadowsweet (Filipendula ulmaria).

[4] Northumberland Wildlife Trust manages 21.2 hectares (52 acres) of the site as a nature reserve with full public access, including provision for wheelchair users.
