Abstract

Abstract: Plant Species with Extremely Small Populations, PSESP, is a conservation concept developed in China aimed at rescuing most threatened plant species of China. The PSESP conservation program was first implemented in Yunnan Province in 2005. Here, we review the development and importance of this concept. Current progress based on the Implementation Plan of Rescuing and Conserving China's PSESP (2011–2015) is highlighted. 120 species were targeted for priority conservation under this program. Based on the PSESP guidelines, several key national and provincial projects supporting practical conservation and research in conservation biology were initiated. While a number of conservation objectives were achieved, unexpected challenges have hindered the fulfillment of five goals that the Plan expected to accomplish by 2015. We provide examples of a successful methodology and the factors supporting these techniques, as well as describe the gaps between scientific research and conservation practices. Finally, we emphasize how interdisciplinary conservation efforts involving multi-stakeholder coalitions with representatives from research institutes, government agencies, non-governmental organizations and local communities should be encouraged to achieve successful PSESP conservation. While this review seeks to facilitate China's tremendous plant conservation efforts to help overcome existing and be prepared for future challenges, the PSESP approach could be valuable in other countries for the preservation of threatened plants.
