Conservation Status

Red List Category & Criteria: Vulnerable

(The assessment of this species in China and Viet Nam were very similar and both concluded on Vulnerable following past decline. The situation in Lao PDR is less well known, but there is likely to have been a similar decline. The area of occupancy is estimated to be less than 2,000 km2 but more than 500 km2. There is a continuing decline in many parts of its range and the population is considered severely fragmented. Hence an assessment of Vulnerable under the A and B criteria is warranted)
