 Also found is Blue eyed Grass (sisyrinchium augustifolium).This species may have been introduced from Ireland in 1959 when the naturalist Bruce Campbell introduced Pitcher Plants and Butterworts as part of a children's programme.Trees and scrub growing are Silver Birch, Scots Pine and Larch which have encroached from the surrounding woodland and plantations.These are being regularly removed by the volunteer group Dean Green Team.
