Abstract:

Biodiversity is especially rich in conservation priority areas. Based on field investigations and available literature, a bryophyte checklist was compiled for the Dabashan and Wulingshan conservation priority areas in Chongqing, China. Species richness and abundance of endemic and threatened species were analyzed. Species compositions were also compared between the two areas. In total, 722 species in 221 genera and 77 families were recorded across the two areas, accounting for 76.0% and 23.9% of all bryophyte species in Chongqing and in China, respectively. Among these, 56 species are endemic to China. One critically endangered (CR), four endangered (EN) and three vulnerable (VU) bryophytes were also found in the two areas. The Jaccard similarity coefficients between the two areas were calculated to be 0.7, 0.6 and 0.3 at the family, genus and species levels, respectively, indicating the big difference of species composition. Dabashan and Wulingshan both have relatively high bryophyte diversity and representative species composition. They are important priority areas not only for Chongqing, but also for overall biodiversity conservation in China.

Key words: bryophytes, biodiversity, species richness, Dabashan, Wulingshan
