Comprehensive Solution for the Rescue and Conservation of the Critically Small Population of Firmiana major

Firmiana major is an endemic species of China. It was declared extinct in the wild by the IUCN in 1998. Later, it was rediscovered in the Sichuan Panzhihua Cycad National Nature Reserve. However, the population size remains extremely small, natural regeneration is limited. The species faces several threats, including low seed plumpness, challenges in seed preservation, harsh habitat conditions in the dry-hot valley, and a lack of protective policies. Integrate field surveys, artificial propagation, in situ conservation, genetic diversity research, and policy advocacy. Core measures include sowing immediately after collection, habitat management. The wild population has increased nearly 400 individuals. More than 500 seedlings have been artificially cultivated. The species has been reclassified as a National Key Protected Wild Plant (Class II), assessed as Endangered (EN) by the IUCN, and its conservation efforts have been integrated into local ecological plans.
