Although there is no direct information available, it seems reasonable given what has happened in this part of China to suspect a 30-49% population reduction in the past three generations (60-75 years) as a result of direct exploitation of the species for its wood and also because of general forest clearance for timber and expanding agriculture. The plant is classified as 'Vulnerable' in the IUCN Red List of Threatened Species(2013)[
