This nature reserve forms part of Aller and Beer Woods Site of Special Scientific Interest (SSSI). It consists of large blocks of semi-natural ancient woodland along the west-facing slope of Aller Hill, overlooking King's Sedgemoor. The woodland canopy is dominated by ash and English oak. A diverse range of fungi grows in the woods including the unusual looking collared earthstar which is scarce in the UK. At dusk you may see badgers emerging from their setts and threatened dormice seek refuge in the woodland. You may also see roe deer and muntjac.
