Abstract:

In order to understand the population status and suitable habitat types of Sphaeropteris lepifera, a rare and endangered plant, this study conducted field investigation and analysis on the distribution areas of S. lepifera in Zhejiang and Fujian, hoping to provide reference for the original habitat protection and field regression of S. lepifera. We analyzed the vegetation types of S. lepifera distribution area, evaluated the distribution status, summarized the existing problems, and proposed protection suggestions after extensively collecting the relevant investigation and research data of S. lepifera, consulting with experts and scholars, and conducting field visits and surveys. The results show that the change of living environment and the destruction caused by human activities are the main reasons for the decrease of S. lepifera in the wild. It is necessary to strengthen the research on the original habitat protection, artificial breeding of seedlings, field regression and endangerment mechanism investigation to increase the number of seedlings and establish ex-situ conservation population of S. lepifera, thus promoting the restoration of its wild population and habitat and protect its germplasm resource.

Key words: rare and endangered species, sphaeropteris lepifera, original habitat, population conservation
