Based on field investigation, the paper preliminarily discussed the floristic characteristics, geographical distribution, ecological environment, relationships with adjacent regions and species endangerment assessment of lycophytes and ferns in Jingning She Autonomous County. 296 species, seven varieties and one hybrid species belonging to 83 genera and 29 families were discovered, including nine new distribution records in Zhejiang Province. The geographical elements of lycophytes and ferns were mainly of tropical nature as to the genera, and the species were mainly of temperate nature. This area belonged to the convergence zone of subtropical and temperate species. Compared with the adjacent provinces and regions, the locophyte and fern flora of Jingning were most similar to those in Jiangxi Province, Fujian Province, Ningbo City and Wenzhou City. They were more close to the flora of Wenzhou and less with Anhui. The ecological types of lycophytes and ferns in Jingning could be roughly divided into six categories: warm coniferous forest habitat, broad-leaved evergreen-forest shady and wet habitat, bamboo thicket warm and wet habitat, temperate pine, fir and cypress cold and wet habitat, drought habitats near shrubs and village roadsides, wetland habitats in streams, farmlands and marshes. Among them, the broad-leaved evergreen-forest shady and wet habitat had the highest diversity of species. There were 46 threatened lycophytes and ferns in Jingning, Zhejiang Province, including 11 endangered species (EN), 35 vulnerable species (VU) and four of them were provincial protected species.
