What are the common invasive alien plants and animals in Shanghai? What survey methods should be used? On the afternoon of July 2, 2023, the Invasive Alien Species Working Group of China Biodiversity Conservation and Green Development Foundation (CBCGDF) attended the Citizen Science Activity Lecture No. 1 on Shanghai Invasive Alien Species Survey: "Introduction to Common Invasive Alien Species in Shanghai and Their Survey Methods".


Deng Shuaitao, Assistant Engineer of Shanghai Wildlife and Nature Reserve Research Center, shared with the audience the main invasive terrestrial animals in Shanghai and their survey methods under the topic of "Invasive terrestrial animals in Shanghai and their survey methods". It is understood that the main invasive terrestrial species in Shanghai include Common Bullfrog, Red-eared slider, Macrochelys temminckii, Coypu, Channeled Applesnail and Giant African Snail. Mr. Deng Shuaitao introduced the identification characteristics, ecological habits, distribution profile and main hazards of the major invasive species, and shared the appropriate survey methods (sample line setup, selection of survey sites and time, etc.) for the characteristics of different invasive species. He also mentioned some other invasive species, such as Common Myna and European Greenfinch.


Xinyan Xu from the Invasive Plant and Invasion Ecology Group of Shanghai Chenshan Botanical Garden introduced in detail the common invasive alien plants and survey methods in Shanghai, one is the line transect method, which is conducted by photographing plants on both sides of the transect while walking; she explained how to select the transect, the selection of the main habitat areas and the information to be recorded, and emphasized the survey principles: Record as many plant species as possible to ensure the integrity of the survey. Another method is the quadrat method. The quadrat method is a survey method in which a fixed area is selected based on vegetation richness and vegetation type, and is now widely used in plant diversity surveys, i.e., the area containing the most species and the smallest area is selected as the quadrat. Similarly, the quadrat method requires the selection of quadrat and habitat areas as well as the comprehensive recording of plant information in the quadrat, including plant species, number of plants, coverage and height in the quadrat, as well as the elevation, latitude and longitude of the quadrat, and habitat information, etc.
