Species components and hazards of alien invasive plants in Putuoshan Island, Zhejiang Province

doi: 10.11833/j.issn.2095-0756.2020.20190538

Abstract:   Objective  Alien invasive plants have huge negative impacts on the biodiversity and ecological security of native ecosystems. This research aims to understand the situation of invasive plants in Putuoshan Island, Zhejiang Province.  Method  Sample surveys were conducted in different areas of Putuoshan Island. According to the weighted statistics of distribution area, coverage and the Zhejiang invasion level, the harm degree and invasion grade of various invasive plants were assessed, and the key harm areas, and prevention and control areas of invasive plants in Putuoshan Island were determined.  Result  There were totally 47 alien invasive species of plants, belonging to 36 genera of 21 families, and all of them being herbaceous. Moreover, out of total observed invasive species, 80.85% (38 species) were found to be native of America. 23 species of plants were in moderate or serious harm, and 22 species could be seen in plants belonging to class Ⅰ and class Ⅱ degree.  Conclusion  Hilly mountains, desolated land and coastal wetlands are important ecological regions of Putuoshan Island where control of alien invasive species is much needed. Since the present situation of invasive plants in Putuoshan Island is serious, it is necessary to increase publicity about bad impacts of invasive species, carry out joint programs to control their spreading, and strengthen the quarantine inspection of alien plants into the island. Additionally, adequate risk assessment of non-native plants should be carried out before their intentional application to prevent and control any invasive hazards in future. [Ch, 1 tab. 31 ref.]
