Abies yunabaoshanensis is assessed as Critically Endangered due to its very restricted distribution and a continuing decline in mature individuals. There is a need for ex-situ conservation and for research on the measures required to prevent it from going extinct.
|Range Description:||A relatively recently discovered species confined to Yuanbao Shan in Rongshui Xian county (N Guangxi,China) which is outside the general range of fir species. The whole population is within an area of 4 ha.|
|Range Map:||Click here to open the map viewer and explore range.|
The population is estimated to number 589 plants. The population structure is skewed to old (senescent) individuals and young ones, with very few middle-aged plants.
Genetic work indicates that this species will face severe genetic issues in the near future.
|Habitat and Ecology:||The highest mountains in Guangxi, like Yuanbao Shan, have a very cool, wet climate, with annual precipitation exceeding 2,000 mm. The summers are cool and cloudy, the winters last four to five months and bring abundant snow from December through March. This species occurs in mixed deciduous-coniferous forest with other conifers (e.g., Tsuga chinensis) and broad-leaved trees dominated by members of the Fagaceae; the Abies trees are very scattered.|
|Major Threat(s):||This species has an extremely limited distribution, distant from other species, and is only known from one small area in Guangxi Province. The population was impacted by a severe winter in 2008 and a number of trees died.|
The population occurs within a protected area.
Further research is required into this species’ threats and what measures should be taken to rescue this species from going extinct.
There is a need for ex-situ conservation.
