and lopped trees, stand height, canopy cover, nearest water source, cattle dung and
distance from the habitation and water etc. was recorded from within these sample
plots as per the formats (Appendix 4). The data of each sampling plot was pooled as
per habitat type for analysis. Bear sighting on both sides of transects and habitat types
of bear locations were recorded.
5.2.2 Availability of food plants
From the vegetation data of different sample plots, assessment of food plants and their
abundance in each habitat type was calculated. The food plants were counted within
circular plot of 10 m radius and shrub species were counted within plot of 5 m radius
for their density estimation. Certain species with 30 cm GBH were considered as
tree and other species with 30 cm GBH were considered as shrub. Identification of
food plants of bear diet was ascertained on the basis of analysis of scats, collected
from the study area.
To assess the habitat use by brown bear in Kugti wildlife sanctuary, availability and
utilization approach of Neu et al. (1974) was adopted here and analysis was done in
the ‘PREFER’ software package developed at the Wildlife Institute of India. During
this exercise, following hypothesis was tested using Chi square test: bear utilized each
habitat category in exact proportion to its occurrence within the study area. To know
the difference between the habitat variables in the plots where bear signs were present
or absent, Kruskal-Wallis non-parametric test was used (Zar, 1984). Multi-
dimensional scaling, regression analysis, and non-parametric analysis were performed
in SPSS software (Norussis, 1994).
