Hotspot analyses indicate significant conservation gaps for evergreen broadleaved woody plants in China
Abstract Evergreen broadleaved woody plants (EBWPs) are dominant components in forests and savanna of the global tropic and subtropic regions. Southern China possesses the largest continuous area of subtropical EBWPs distribution, harboring a high proportion of endemic species. Hotspot and gap analy...
