Abstract:

To clarify the current status of Michelia guangdongensis germplasm resources and evaluate its endangerment category, a field investigation was conducted in Guangdong Shimentai National Nature Reserve and its adjacent regions. The results are as followings: (1) We found a total of four wild distribution areas for Michelia guangdongensis, with two (Guangdong Shimentai National Nature Reserve and Shangtiantang, Yingde) of first reports. (2) Chuandiding harbors the largest population with 1,100 individuals, whereas Shangtiantang, Yingde, the smallest, with only about 20 individuals. (3) According to the IUCN Global Species Threat Assessment Standard, Michelia guangdongensis was rated as Endangered (EN, B1a + B2a).
