Abstract
The catastrophic decline of the endangered Green peafowl Pavo muticus across its former range
is well known, yet there are only a handful of reliable population estimates for this species from
its remaining range, making global assessment challenging. We present the first rigorous population
estimates for this species from Cambodia, and model the distribution and the relationships
between this species and several environmental covariates from the Core Zone (187,900 ha) of
Seima Protection Forest (SPF), eastern Cambodia. Using distance sampling the abundance of
Green Peafowl in SPF in 2014 is estimated to be 541 (95% CI [252, 1160]). Density surface modelling
was used to predict distribution and relative abundance within the study area, and there was
some evidence that the species prefers areas of deciduous forest, non-forest, and to a lesser extent
semi-evergreen forest. These results highlight the importance of the central and northern sections
of SPF for this species. Furthermore, the analysis suggested that Green Peafowl abundance
is higher in closer proximity to water, yet decreases in closer proximity to human settlement.
