Abstract
There are plenty of native tree species in east China, including 16 rare and endangered tree species belonging to 11 genera in 10 families. Because of narrow distribution area, weak qualitative competitiveness and reduced natural regeneration, the number of these tree species are decreasing substantially. Thus, it is necessary to protect endangered species endemic to the region. In this paper the basic data on germplasm, geographical distribution, biological characters, endangered status and current conservation strategies of rare and endangered species endemic to east China are presented. The gap areas were identified and accordingly implications were made on the future work on the native rare and endangered tree species in east China should focus on the basic research of conservation biology, establishment of the information system, solution of problems in reproductive biology and more emphasis on the key regions for protecting biodiversity.
Highlights
East China is a geographical region having an area of 65.86 square kilometres that covers the south-eastern coastal zone of China, including provinces of Zhejiang, Jiangsu, Shandong, Fujiang, Jiangxi, Anhui and Shanghai (Wu & Wang, 1983; Liu et al, 1995)
The germplasm of endangered tree species endemic to east China is an important part of the biodiversity of the region
An information system on endangered tree species endemic to east China needs to be established based on these data which would assist to develop conservation strategies
Summary
East China is a geographical region having an area of 65.86 square kilometres that covers the south-eastern coastal zone of China, including provinces of Zhejiang, Jiangsu, Shandong, Fujiang, Jiangxi, Anhui and Shanghai (Wu & Wang, 1983; Liu et al, 1995). Germplasm and conservation of rare and endangered tree species endemic to east China. Due to special geographical environment and climatic conditions, there are so many rare and endangered tree species endemic to east China, such as Abies beshanzuensis, Sinocalycanthus chinensis, Ostrya rehderiana and Magnolia cylindrica.
