b) Estimation of ungulate species across study sites
Individual density of all the species was calculated using Distance
program version 6.2 (Thomas et al., 2010). We first examined the data
from both sites for each species separately. Following this, the species
observations at distances beyond which sightings were almost none was
dropped or observations were binned to achieve model fit. Akaike
Information Criterion and goodness-of-fit (GOF-p) tests were used to
judge and the fit of the model. Based on the selected model, individual
density (\(\ \hat{\text{Di\ }}\)) and estimates of group density
(\(\hat{\text{Dg}}\)) were derived for each species.
