Abstract:

Shibing karst World Natural Heritage nominated property is rich in bryophytes because of its superior geography, huge elevation difference, high heterogeneity in habitats, and little human disturbance. A total of 286 species of bryophytes (including subspecies and varieties) in 128 genera, 50 families were found. There were 43 species of Hepaticae in 23 genera, 17 families and 243 species of Musci in 105 genera, 33 families. Both the dominant families and genera suggest that the bryoflora of Shibing karst area is transitional between temperate zone and tropic. The phytogeographical elements were dominated by northern temperate elements (3712%), tropical elements (3182%) and eastern Asia elements (3030%), while areapattern of endemic to China occupied 1212%. Therefore, the bryoflora of Shibing karst area is of the nature of both the temperate and tropical elements, and possessed strong easternAsia colour and relatively high endemism. The results of comparison with other five sites show that the species abundance of Shibing karst area was higher and its bryoflora was most similar to Xiangzhigou, Malinghe and Luoping karst areas in YunnanGuizhou Bryological Region.

Key words: Phytogeographical element, Species abundance, Shibing Karst World Natural Heritage nominated property
