Magnolia aromatica is classified as Endangered as only a few scattered stands of this important timber tree remain. Several subpopulations are reported to have become extinct in Chinese provinces, largely as a result of  over exploitation of the timber. Similar pressure affects the potential subpopulations in Viet Nam. The species is also threatened by habitat loss due to agricultural expansion. There are less than 2,500 mature individuals remaining with each subpopulation consisting of less than 250 mature individuals. Ex situ conservation collections have been made and reintroduction trials are taking place.

Geographic Range [top]

Range Description:Magnolia aromatica is native to south China (Yunnan, Guizhou, Guangxi). It occurs at altitudes of between 800 and 1,600 m asl in a range stretching from southeast Yunnan to southwest Guangxi, with a potential forest distribution, used here as an estimate of the extent of occurrence (EOO), of 39,605 km2. Within this range, subpopulations are scarce and subject to pressure with a number of subpopulations already known to have been lost. The area of occupancy is considered to be very low and only 0.3 km2 in Yunnan. The species may also occur in the trans-border forests of northeastern Viet Nam, however, no specimen data have been found to support this.

Population [top]

Population:Magnolia aromatica remains as only a few scattered stands. Several subpopulations are reported to have gone extinct, including the type locality (Pan et al. 2003). The total number of remaining mature individuals is estimated to be between 2,000 and 2,500. All subpopulations consist of less than 250 mature individuals.
Current Population Trend:Decreasing
Additional data:
Number of mature individuals:2000-2500Continuing decline of mature individuals:Yes
Extreme fluctuations:NoPopulation severely fragmented:Unknown
Continuing decline in subpopulations:Yes
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:No

Habitat and Ecology [top]

Habitat and Ecology:Magnolia aromatica trees grow up to 35 metres tall in monsoon evergreen broad-leaved forests on limestone hills. the species produce a lot of flowers and fruits each year, but the seed set and the reproductive capacity is low (Pan et al. 2003). The reason for reproductive abortion is likely to be due to genetic factors.
Continuing decline in area, extent and/or quality of habitat:Yes
Generation Length (years):10-200,60

Use and Trade [top]

Use and Trade: Magnolia aromatica is primarily used for its timber.

Threats [top]

Major Threat(s): Overexploitation of the timber is the major threat. The habitat in southern China is also subject to habitat decline, degradation and fragmentation due to logging and agricultural expansion. The species is targeted because of its aromatic timber is known to be resistant to rot (Pan et al. 2003).

Conservation Actions [top]

Conservation Actions: Magnolia aromatica exists in ex situ conservation collections in Viet Nam and China and is subject to reintroduction trials in Daweishan Nature Reserve, Pingbian County, Yunnan. In 2009, 10 seedlings were introduced into Kunming Botanic Gardens. It was listed as Endangered in the China Plants Red Data Book (1992) and in the latest national assessment on the Chinese Red List of Higher Plants (2013) it is listed as Vulnerable.
