Conservation Threats of White-Bellied Heron (Ardea insignis) in Zhemgang District, Bhutan

Abstract

The study was conducted in 2018 along the Mangdechhu river basin and Bertichhu stream of Zhemgang district, which are the important habitats for White-bellied Heron (Ardea insignis) in Bhutan. We have documented the anthropogenic threats, directly affecting the survival of the species through focal sampling along established transects at the study area. The major anthropogenic threats leading to the habitat degradation encountered were overhead hydropower transmission lines installed across the river/stream, firewood collection from riverbank, sand/stone quarry, temporary cattle herding camp and grazing, camping/picnicking and fishing. This study found that the sites used for foraging and resting by the species should be strictly monitored and protected from the human disturbances.
