Group 1: Conservation Efforts - The reserve, established in 1996, focuses on the protection of cycad species, with significant improvements in the population and distribution of wild Panzhihua cycads [1]. - Mining activities that previously threatened the cycad population were halted in October 2018, followed by ecological restoration completed in October 2019 [1]. - The area of the reserve is 1358.3 hectares, which is relatively small, yet it has shown remarkable conservation results [1]. Group 2: Population Growth and Distribution - The population of wild Panzhihua cycads has reached 389,200 individuals, with a growth rate exceeding 60% over 29 years [1]. - The wild distribution area of the cycads has increased from 620.2 hectares to 750.2 hectares, representing a growth rate of over 13% [1]. - Genetic studies indicate a near 1:1 sex ratio in the cycad population, suggesting ongoing population growth [2]. Group 3: Recognition and Significance - The Sichuan Panzhihua Cycad National Nature Reserve is recognized as the largest, highest altitude, and most concentrated natural cycad community in Eurasia [2]. - The successful inclusion of the reserve in the latest IUCN Green List of Protected Areas underscores its significance in global conservation efforts [1].
