The following species have all been lost from the Caledonian Forest in historic times, due to human
exploitation and habitat destruction. With 99% of the original forest having been destroyed, undoubtedly
there are other less-obvious species (eg of plants, insects, fungi etc) that have also been lost, but
there are no records to confirm this.
Trees for Life advocates the reintroduction of all these missing species in due course, as they each
play an essential role in the ecosystem, and there will never be a healthy self-sustaining forest in the
Highlands until all the constituent species, especially the large mammals, are back again.
