Distribution and conservation of threatened gymnosperms in China

China is one of the diversity centers of gymnosperms. Nearly one-fifth (195 species) of gymnosperms are located in China, but 69 species are threatened. To date, the conservation status of gymnosperms, especially threatened gymnosperms in China, remains largely unknown, which seriously restricts the...

Nearly one-fifth (195 species) of gymnosperms are located in China, but 69 species are threatened.

In this study, we first constructed a database for the 69 threatened species of gymnosperms with 13 270 distribution records.

We should give more attention to unprotected threatened gymnosperms and conduct taxonomic studies on the species without detailed distribution records. Finally, conservation priority areas and priority conservation levels of threatened gymnosperms in China were proposed.
