Bracken can be a potential problem on heathland sites. Bracken was initially only present in sections 1 and 2, but it had spread by 1998 and was found with a relatively low frequency over most of the project site (Figures below).

Its mean % cover increased in 1997, but declined to a very low level in 1998 (Figures below). Its greatest abundance was in the sections bordering the woodland (1,2 and 8,9).
