| Description | We used capture-recapture analyses to estimate the density of a tiger Panthera tigris population in the tropical forests of Huai Kha Khaeng Wildlife Sanctuary, Thailand, from photographic capture histories of 15 distinct individuals. The closure test results (z = 0.39, P = 0.65) provided some evidence in support of the demographic closure assumption. Fit of eight plausible closed models to the data indicated more support for model $M_{h}$, which incorporates individual heterogeneity in capture probabilities. This model generated an average capture probability $\hat p$ = 0.42 and an abundance estimate of $\widehat{N}(\widehat{SE}[\widehat{N}])$ = 19 (9.65) tigers. The sampled area of $\widehat{A}(W)(\widehat{SE}[\widehat{A}(W)])$ = 477.2 (58.24) $km^{2}$ yielded a density estimate of $\widehat{D}(\widehat{SE}[\widehat{D}])$ = 3.98 (0.51) tigers per 100 $km^{2}$. Huai Kha Khaeng Wildlife Sanctuary could therefore hold 113 tigers and the entire Western Forest Complex c. 720 tigers. Although based on field protocols that constrained us to use sub-optimal analyses, this estimated tiger density is comparable to tiger densities in Indian reserves that support moderate prey abundances. However, tiger densities in well-protected Indian reserves with high prey abundances are three times higher. If given adequate protection we believe that the Western Forest Complex of Thailand could potentially harbour >2,000 wild tigers, highlighting its importance for global tiger conservation. The monitoring approaches we recommend here would be useful for managing this tiger population. |
