Project Name:

Understanding the population biology of the critically endangered point endemic, the Bugun Liocichla, to design effective conservation strategies

Project Brief:

The Singchung Bugun Village Community Reserve (SBVCR) and Eaglenest Wildlife Sanctuary (EWS), located in the Eastern Himalaya Global Biodiversity Hotspot, are renowned destinations for birdwatching and wildlife tourism. Tourism here is sustainable, high-income, and low-impact, driven by the region's remarkable bird diversity, particularly the critically endangered Bugun Liocichla (Liocichla bugunorum). With a global population of only 14 to 20 individuals, this species is found exclusively within a small area of just two to three square kilometres.

In 2017, the Bugun community of Singchung village established the 17 sq. km SBVCR to protect most of the Bugun Liocichla habitat. In 2024, they expanded efforts by creating the 15 sq. km Braiduah Community Reserve (BCR). Both reserves are patrolled by local rangers to prevent hunting and forest fires. However, the species' small population remains highly vulnerable to extinction due to demographic and environmental risks, including extreme weather, requiring urgent action.

Project objectives:

The project has the following objectives:

  • To estimate the current effective population size (i.e., number of breeding individuals) of the Bugun Liocichla.
  • To apply population genetics techniques to:
    1. Estimate recent effective population size and pre-disturbance effective population size, and determine target population sizes necessary for stability.
    2. Assess if there are genetic constraints to creating in-situ or ex-situ reserve populations of the species.
    3. Simulate the demographic parameters required for sustaining such a small population and develop conservation guidelines for the Bugun Liocichla.
