Justification

This species is very rare and now possibly extinct in neighbouring countries such as Thailand, Laos, Cambodia, China and Vietnam. The majority of the global population is widespread in India, Pakistan and Nepal. Even though this species is not migratory and geographically not possible to colonise here in Myanmar, the Myanmar population can still grow by themselves.

National Redlist of Threatened Species in Myanmar

PDF

The Myanmar National Red List of threatened species contributes to the GEF funded “Strengthening Sustainability of Protected Area Management in Myanmar” project. To support the National Biodiversity Strategy Action Plan (2015-2020), Target 12 for commitment to prevent the extinction of known threatened species and improve their conservation status, the National Red List of some selected taxa has been produced. This report summarizes the assessment process and its results with detailed descriptions for some selected threatened species in Myanmar.
