Abstract
dc.description.abstract
Forestry plantations of Pinus radiata, managed through clearcutting method, would offer
resistance to the movement of native fauna among remnants of native forest. In this study,
we evaluate the possibilities of establishing connectivity corridors for native fauna in a
forest landscape dominated by P. radiata, focusing on seven species with some level of
specialisation in the use of different land covers and that exhibit different movement
strategies. We sampled presences and abundances using several types of sampling to
determine the abundance and crossing edge probabilities for the ground-dwelling beetle
Ceroglossus chilensis; the mesocarnivores Conepatus chinga, Lycalopex culpaeus and Leopardus
guigna; the terrestrial frogs Eupsophus septentrionalis and Pleuroderma thaul, and the
understory bird Pteroptochos castaneus. We use species distribution modelling and circuit
theory to calculate connectivity for each species. Finally, a spatial priorization approach
was applied to obtain two scenarios of least-cost corridors. The results show that species
with more specific requirements such as L. guigna, P. castaneus, P. thaul and E. septentrionalis,
are unlikely to move through clear cuttings and young plantations, but their
movement is possible through adult pine plantations with understory. For species that are
habitat generalists such as C. chinga and L. culpaeus plantations were suitable for movement.
The management of forest plantations should use multi-taxa assessments in the
design of biological corridors that allow the connection of forest fragments.
