India’s only extant red deer species, the Kashmir red deer, or hangul (Cervus hanglu hanglu) is restricted today to the confines of the 141 sq. km Dachigam National Park (NP) in Jammu and Kashmir, with about 200 surviving individuals. A continual population decline of hangul has necessitated the identification of relict populations and suitable habitats outside Dachigam NP, so that a meta-population approach to its conservation may be employed. Extensive surveys in 2008–2012 across the Kashmir valley, helped identify three distinct areas, where the presence of the red deer was confirmed year-round. Ecological Niche Factor Analysis results indicated that hangul exhibits high global marginality (1.24) and low global tolerance (0.28). Habitat suitability modelling predicted 610.75 sq. km area of conifer and temperate broadleaved forests as highly (61–100%) suitable and 980.25 sq. km as moderately (31–60%) suitable, primarily in two distinct areas of Wanghat Naranag and Chandaji, which also showed presence of the hangul year-round. This suggests that apart from Dachigam NP, suitable habitats bearing hangul populations still exist in Kashmir valley (935.46 sq. km), emphasizing the need to urgently direct protection and conservation focus to these areas to conserve hangul successfully in this landscape.Keywords

The change in physiognomic and floristic characteristics of vegetation composition affects the bird community assemblage and the relative abundance of different species within the community. Hornbills are mutualistic to the forest with their dependency on roosting, nesting and feeding, and helping in the regeneration of different plant species by dispersing the seeds. The relationship between various vegetation characteristics and the relative abundance of three hornbill species (Great Pied Hornbill (GPH, Buceros bicornis), Wreathed Hornbill (Rhyticeros undulatus) and Oriental Pied Hornbill (OPH, Anthracoceros albirostris)) was studied in and around Pakke Tiger Reserve, Arunachal Pradesh, India. We walked transects (n = 11; 22 walks) in three study sites to detect hornbills. Vegetation sampling was done using circular plots (n = 33; 10 m radius) at every 400 m interval along each transect. Encounter rate (1.5 ± 0.188/km) of GPH was highest in the protected and undisturbed forest area, where food and roosting tree density were also high (114/ha). OPH was common in both the sites in the Reserve, near riverine forests (0.75 ± 0.25/km) and the dense undisturbed forest (0.875 ± 0.226/km). Multivariate analysis revealed that tree density, presence of fruiting trees (utilized by hornbills), canopy cover and tree diversity in a particular area are the major factors responsible for the assemblage of more than one hornbill species. The study shows that protection of forest patches to keep the diversity and density of the tree species intact is crucial for the survival and distribution of hornbills in the landscape.Keywords
