Habitat associations of old forest bird species in managed boreal forests characterized by forest inventory data
Conservation areas are important for many species associated with old forests, but most individuals still occur in commercially-used forest landscapes. We conducted three-visit 2 breeding bird surveys in a total of 37 study squares of 1 km , and used National Forest In- ventory data to evaluate habi...

Conservation areas are important for many species associated with old forests, but most individuals still occur in commercially-used forest landscapes. We conducted three-visit 2 breeding bird surveys in a total of 37 study squares of 1 km , and used National Forest In- ventory data to evaluate habitat associations of birds linked with old forests in three geo- graphical regions: southern, eastern and northern Finland. All study squares were located within managed forests. Out of the total of 23 pre-selected old-forest species, 12 were re- corded in the study squares of all three study regions; the number of species varied be- tween 16 and 21 among the regions. The total abundance did not significantly vary among the regions, but the abundances of many single species varied significantly among the re- gions.
