is necessary to provide habitat for birds specialists to offset the negative effect of forest loss
birds inhabiting the temperate forests of Chile may be especially sensitive to habitat fragmentation. Their abundances decrease in disturbed forest fragments or very small ones that are left isolated in cultivated fields. There is still uncertainty in the human impact of fragmentation at different spatial scales on the organisms that inhabit the fragments. Armesto Vergara and analyzed the responses of bird species to fragmentation at different spatial scales and found that nine of 20 species are affected in their abundance. The patches that are suitable habitat, such as coverage of dense undergrowth and large trees are underutilized or not used in highly fragmented landscapes. Bird habitat specialists, such as those that occupy crevices or logs and the " tapaculos " were the most affected. The authors stress the need to provide habitat for these birds to offset the negative effect of forest loss. For example, conservation strategies should ensure the retention of native forest patches in landscapes with multiple uses.
