Knockeyon and other surrounding hills support
deciduous woodland which mostly consists of native species.
Hazel,
rowan,
ash, and
oak are abundant. Exotic species occur occasionally, such as horse chestnut and other species introduced including
beech. The neighbouring Knockbody Wood is inhabited by wild
pheasant and is a popular attraction for local pheasant hunters. On occasions, the
Common pochard (
Aythya ferina) population, which is one of the largest in Ireland, has exceeded the threshold for international importance. (i.e. 3,500 individual fowl). ==References==
