Magnolia amoena is found only in China but is scattered across many provinces. The population is highly fragmented and collection of flower buds for medicinal purposes is believed to be reducing its ability to regenerate. It occurs in small scattered stands in hilly lowland mixed forest so the extent of occurrence is likely to be much less than the forest extent of 24,769 km2 and is estimated at less than 20,000 km2. It is listed as Vulnerable in the China Plants Red Data Book.

Geographic Range [top]

Range Description:Magnolia amoena is endemic to southeast China where it occurs in south Anhui, south Jiangsu and Zhejiang provinces. This species is found in a restricted area just south of the mouth of the Yangtze River and is not thought to occur anywhere in large numbers, occurring instead in small scattered stands at elevations of 700-1,000 m asl. Scattered individuals have been recorded on the Huanggangshan, Jiangxi/Fujian border, Wuyishan Biosphere Reserve. The area of forest remaining for this species is estimated to be 24,769 km2 but the species is scattered and likely to occur in an area much smaller than this, with an extent of occurrence of less than 20,000 km2 
Countries occurrence:
China (Anhui, Jiangsu, Jiangxi, Zhejiang)

Population [top]

Population:Subpopulations of Magnolia amoena are small and scattered and it does not exist anywhere in large numbers. The genetic diversity between individuals within subpopulations was found to be lower than that between subpopulations. The individual genetic differentiation might be relation to the geographic distribution. The low total genetic diversity of Magnolia amoena was one reason for its endangerment (Liu et al. 2007).
Current Population Trend:Decreasing
Additional data:
Continuing decline of mature individuals:Unknown
Extreme fluctuations:NoPopulation severely fragmented:Yes
Continuing decline in subpopulations:Yes
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:No

Habitat and Ecology [top]

Habitat and Ecology:Magnolia amoena trees grow up to 12 m in height and are found in hilly lowland and montane mixed forest.
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: The collection of flower buds for medicinal purposes is believed to be affecting the regeneration of Magnolia amoena. 

Threats [top]

Major Threat(s): The small scattered populations are under threat from a continuing decline in its extent of occurrence and area of habitat. Very poor seed production and the occurrence of few saplings under the parent trees is the result of bud-collection for medicinal purposes by the local inhabitants which is believed to be the greatest threat to this species.

Conservation Actions [top]

Conservation Actions: It is known to occur in Wuyishan Biosphere Reserve and Mt. Xitianmu reserve. In the mid 1950s it was brought into cultivation in the Hangzhou Botanical Garden (Li-kuo 1992).
