Avian species distribution along elevation at Doon Valley (foot hills of western Himalayas), Uttarakhand, and its association with vegetation structure

We assessed a diverse avian population during February 2013 to February 2014 at Doon Valley forest. During the study period we recorded a total of 218 species (18,982 individuals) belonging to 50 families using line transect along with the fixed radius point count method in the study area. Avian spe...

Description
Summary:We assessed a diverse avian population during February 2013 to February 2014 at Doon Valley forest. During the study period we recorded a total of 218 species (18,982 individuals) belonging to 50 families using line transect along with the fixed radius point count method in the study area. Avian species diversity, richness, and abundance showed a hump-shaped distribution pattern in the study range (325–2300 m above sea level). The association of vegetation structure with avian community illustrates the significantly positive correlation with shrub diversity and density/ha along the elevation. The presence of new records (habitat area extension), endangered species, and two near-threatened species concerns the conservation of birds and forest habitat in this area.
