Dundreggan, lying on the north side of Glenmoriston to the west of Loch Ness, is home to declining species such as black grouse and wood ants. It contains areas of ancient woodland, including one of Scotland's best areas of juniper as well as significant areas of dwarf birch; however, much of the estate is open treeless ground. It was previously managed as a traditional sporting estate for many years, and heavy grazing by sheep and deer has prevented the healthy growth of woodland and other natural habitats. Trees for Life's purchase of the estate will allow them to plant 500,000 native trees and re-connect the forest between Glen Moriston and Glen Affric.
