Land-cover change and the future of the Abruzzo brown bear: a perspective from the past
The Apennine brown bear (Ursus arctos marsicanus) is an endangered subspecies endemic to Italy, where a small population, estimated at 40–50 bears, inhabits a human-dominated landscape. Although little is known of the ecology of this population, habitat loss and fragmentation often has been consider...

Our results show that, at the landscape level and assuming that current human population trends continue in the future, land-cover suitability does not seem to be an issue or priority. The current negative trend of this population, despite opposite trends in land-cover suitability, suggests that conservation efforts should focus more on direct actions aimed at reducing human-caused mortality and enhancing population expansion into suitable unoccupied areas.
