• Resumen

  • The objective of this thesis is to analyze the effect of the transformation in the habitat that postfire salvage logging supposes on birds in Mediterranean pine forests, at different levels: species, community and ecosystem, focusing on the bird-mediated seed dispersal process. Salvage logging with commercial purposes is the main factor that determines the species composition after a fire, with the substitution of forest birds by open-habitat species, some of which hold an unfavourable conservation status in Europe. On the other hand, wood debris piles built by non-profitable burnt wood favour the presence of seed disperser frugivorous birds, and these structures show more seed dispersal than other microhabitats, and a higher abundance of bird-dispersed plants, so that it is recommendable to build them in managed burned forests.
