The site contains three species of plant which are nationally rare and a further three which are of restricted distribution in Somerset. The central area contains a sward dominated by sheep's fescue (Festuca ovina) in combination with yellow oat grass (Trisetum flavescens) and quaking-grass (Briza media). Salad burnet (Sanguisorba minor) forms a major component of the sward with rough marsh-mallow (Althaea hirsuta) and nit-grass (Gastridium ventricosum), two nationally rare species, also present.[1] Aller and Beer Woods on the slopes of the hill are also designated as a biological Site of Special Scientific Interest.
