|Assessor(s):||Global Tree Specialist Group|
Magnolia sargentiana was previously classified as Endangered, however, further survey work has revealed extensive and protected populations in southern Sichuan of at least 20,000 individuals. It is threatened by habitat clearance and exploited for medicinal use which is a threat to the remaining forest habitat, with an area of occupancy of 860 km2. The areas where the extensive populations occur are protected within reserves.
|Previously published Red List assessments:|
|Range Description:||Magnolia sargentiana is endemic to China where it has a wide but very fragmented distribution in Sichuan and Yunnan. The total area of mixed forest habitat and area of occupancy of this species are estimated at 860 km2.|
Native:China (Sichuan, Yunnan)

|Population:||It was thought that only around 40-50 trees of Magnolia sargentiana remained in Yunnan but Global Trees Campaign field surveys in April 2006 recorded 12 sites with a total population estimated at about 20,000. A Sichuan University/University of British Columbia Botanical Garden team recorded extensive and protected populations in two of four main reserves in the Dafengding region of southern Sichuan covering at least 60,000 ha of mixed evergreen/deciduous forest, during fieldwork in September 2006. Peripheral areas covering approximately a further 20,000 ha have generally good protection and regeneration.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||Magnolia sargentiana trees grow between 8 to 25 metres tall in evergreen and deciduous mixed forests.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Use and Trade:||The bark of Magnolia sargentiana trees is used in traditional medicines. The wood is also utilised.|
|Major Threat(s):||Magnolia sargentiana is threatened by forest clearance to make way for Gastrodia planting, cutting for wood and gathering of its bark for use in traditional medicines.|
|Conservation Actions:||There are no known conservation actions proposed for Magnolia sargentiana, however, peripheral areas covering a large proportion of its distribution have good protection and regeneration. This species is absent from ex situ collections.|
|Errata reason:||A spelling error in the name of the University of British Columbia Botanical Garden has been corrected.|
