Corylus avellana (Hazel)

Corylus avellana is commonly found in the under-storey of damp oakwoods, and sometimes can dominate the shrub layer of ash woods (Rodwell 1991), today often in abandoned coppice form. It can form scrub communities on exposed limestone, tending to prefer basic soils, or neutral moderately acidic soils. Natural hazelwoods can be found in the Lake District and in western Scotland although it is not a mountain tree (Wilkinson, 1976). It is not so abundant in north-western siliceous hillside oakwoods, (although not rare) and this is no doubt a result of the absence of coppicing in those parts of the country. Corylus avellana flourishes on calcareous soils and is therefore abundant in the ashwoods on mountain Carboniferous Limestone in Derbyshire, where it often forms pure coppices. It is a frequent constituent of chalk scrub in the south where it can sometimes form the pioneer in colonising grassland (Tansley, 1939).
