Resources and protection of <i>Cycas</i> plants in China

Abstract

Background & Aim: Cycads include two families and 10 genera, representing one of the most primitive taxa of the extant seed plants, and hold important value to scientific research and conservation.Among cycads, only about 20 species within the genus Cycas have a natural distribution within China, most of which are also endemic to China.These species are primarily found in the southwest and southeast coast of China, with most occupying a narrowly distributed area.All species in this group of Cycas have been classified as first-class national key protected wild plants in China due to the existence of serious threats to their survival and reproduction.In this review, we aim to familiarize members of the public with these important plants while also encouraging their protection.Methods: This paper summarizes the status of research and protection of cycads in China by aggregating data available from the published literature and our field investigations.Result: By summarizing the taxonomic research and geographical distribution of cycads in China, we highlight the principal threats to the survival of cycads in China and describe protective measures that can be used to counter these threats.Further, we suggest that certain scientific evidence, such as genetic characteristics, are critical factors when determining effective methods of protection.•综述• 纪念第19届国际植物学大会召开5周年专题
