This study was started in the spring of 2010 with the purpose of examine the forestal features that frequently occurring in Tengmalm’s Owl’s habitat in breeding season. Distribution in Belluno Province has been verified by nightly census; there were identified 12 occupied territories from this specie, and the data from these censuses have been used for the species biology. In 4 areas located inside and outside the “Parco Nazionale Dolomiti Bellunesi” was carried out a structural study, detecting the dendrometric parameters. The analysis shows that stand density, height of canopy insertion, top height, basal area, crown depth and the number of vertical layers of the forest influence Tengmalm’s Owl’s choices. The results of this study shows that this Owl prefers not too high mature densities in multilayered forestal formations, between submountain and mountain plane, with coniferus and some open areas.

Abstract

This study was started in the spring of 2010 with the purpose of examine the forestal features that frequently occurring in Tengmalm’s Owl’s habitat in breeding season. Distribution in Belluno Province has been verified by nightly census; there were identified 12 occupied territories from this specie, and the data from these censuses have been used for the species biology. In 4 areas located inside and outside the “Parco Nazionale Dolomiti Bellunesi” was carried out a structural study, detecting the dendrometric parameters. The analysis shows that stand density, height of canopy insertion, top height, basal area, crown depth and the number of vertical layers of the forest influence Tengmalm’s Owl’s choices. The results of this study shows that this Owl prefers not too high mature densities in multilayered forestal formations, between submountain and mountain plane, with coniferus and some open areas.
