Core Viewpoint - The article discusses the serious threat posed by invasive alien species to ecological security, food security, and biodiversity in Guangdong, emphasizing the need for scientific prevention and control measures to address this global issue [2][5][20]. Group 1: Invasive Species Threat - Invasive alien species are a global challenge that continues to threaten ecological, food, and biological security [2][5]. - Guangdong, as an important ecological model and agricultural core area, is particularly vulnerable to the spread of invasive species due to its favorable climate and rich resources [9][10]. - Various invasive species have already caused significant harm, such as the widespread presence of golden apple snails across 21 cities in the province, affecting over 10 million mu of rice fields [14][17]. Group 2: Prevention and Control Measures - Guangdong is actively promoting early warning and eradication measures, improving prevention and control methods and technologies to establish a comprehensive control system for invasive species [20][21]. - The urgency of intervention is highlighted, as once invasive species gain ecological advantages, the remediation period could extend beyond ten years [22][23]. - The event aimed to achieve three core objectives: to eliminate harmful species like golden apple snails and Wedelia trilobata, to popularize scientific prevention techniques, and to promote a provincial joint prevention and control mechanism [24][26]. Group 3: Scientific Approach and Techniques - The event showcased a scientific approach of "one species, one strategy, precise control" for managing common invasive species [30]. - Experts provided detailed explanations of identification points and control techniques for invasive species, demonstrating effective physical and chemical control methods [29][33]. - For example, the use of specific herbicides for Wedelia trilobata showed a high efficacy rate of over 95% when applied correctly [36]. Group 4: Collaborative Efforts - The event emphasized the importance of social collaboration in protecting ecological and food security, involving government leadership, scientific support, corporate participation, and public action [56][61]. - There is a recognized need for increased public awareness regarding the dangers and identification of invasive species, making educational outreach essential [57][58]. - By enhancing public understanding and engagement, the threats posed by invasive species to ecological environments and agricultural safety can be effectively mitigated [60][62].
