In order to further study the spatial distribution and succession change of plant community, reveal the ecological adaptive mechanism of local plants, promote the ability of vegetation restoration and stony desertification control in the southwestern Karst region, Institute of Subtropical Agriculture (ISA), the Chinese Academy of Sciences (CAS) discussed the frame of long-term comprehensive cooperation with the Administration Bureau of Guangxi Mulun Karst National Nature Reserve. Prof. Kelin Wang, the director of ISA and stationmaster of Huanjiang National Experimental Station of Karst Ecosystem, made a cooperative agreement with Jianbang Ge, the managing director of the Administration Bureau of Guangxi Mulun Karst National Nature Reserve. The both sides will jointly establish a large-scale fixed standard plot in Mulun Karst National Nature Reserve, develop the long-term location studies in the ecological environment, disturb of human activities, soil types and characteristics, and specific name, life-type seasonal appearance, density, sociability and community structure of plants, apply for the various national and local scientific research projects, share the cooperation achievements, enhance the research ability and level of Mulun Karst Nature Reserve in ecology, and establish a protection garden of ex situ plants in the park region of Karst ecological station.

Mulun Karst Nature Reserve, located in the northwest of Huanjiang Maonan Nationality Autonomous county, Guangxi province, with a total area of 109 square kilometers, approved as a Karst National Nature Reserve by the State Council in August, 1998. The Reserve belongs to the typical mixed evergreen deciduous and broadleaf forestry ecosystem of subtropical lime stone, and is extremely rare in the same latitude area all over the world with its intact preserves and aboriginality (the coverage rate is up to 97%). This Reserve is the implicit domain of Karst forestry vegetation climax community with rare and endangered species resources. There are about 910 kinds of vascular plants and 408 kinds of indentified insects, and kmeria septentrionalis community named as “panda” in this plant kingdom. It is also a genuinely natural Karst plant garden for about 108 kinds of rare orchid varieties growing in the Reserve.(Dec. 22, 2008)
