The Research Of The Vegetation Species And Phytophagous Food Of The Tragopan Caboti Habitat In Wu Yan Ling Protected Areas.

The Tragopan caboti is one of rare bird endemic to China, being one of the state-protected first class wild animals, which has been listed as world birds species. Currently the Tragopan caboti's distribution area is very narrow, only distributed in part of the forests, such as southwest of Zhejiang, Hunan, Jiangxi, Fujian, northern of Guangdong, northeastern of Guangxi. It is estimated that the population of the Tragopan caboti is about 4000. Taking Wu Yan Ling protected areas as research sites, the paper will investigate and analysis the community structure and the species of vegetation in the area where the Tragopan caboti habitat, and survey the phytophagous food which the Tragopan caboti eat in the area a year, and find the law in it. The results indicated that:1. The population of the Tragopan caboti in the area is nearly 400. egetations in reserve are mainly divided in to 8 species, thereinto evergreen broad-leaf forest, evergreen and deciduous broad-leaved forest, mixed coniferous and broad-leaved forest are 3 optimal habitat vegetation species for the Tragopan caboti. The Tragopan caboti usually habitat a place where the cover degree of tree layer is 60—85%, shrub layer is 40—60%, herbaceous is 15—30%. In such environment of habitat the ratio of The Tragopan caboti's distribution activities is 80% above. The main species of tree which constitute of vegetation tree layer of the Tragopan caboti's habitat are Fagaceae, Lauraceae, Taxodiaceae, the Shrub layer's species mainly include Theaceae, Rosaceae, Ericaceae et, while the Herbaceous layer's species mainly include ferns, grass-based. There are 498 species of the vascular bundle plant in the Tragopan caboti's habitat in the survey, including 10 species,5 families of gymnosperms,431 species,67 families of angiosperm,57 species,20 families of ferns, the families which constitute the zonal vegetation in the reserve are mostly composed of sub-tropical flora.2. Tragopan caboti mainly through ground find their food, the statistics of the phytophagous food are 38 families,131 species, accounting for 26.3% of the species of the habitat's plant,6.1% of the species of the vascular bundle plant in the Rock Ridge Nature Reserve. The types of the plants and their parts eaten by Tragopan caboti change with seasons:Tragopan caboti mainly eat the leaves, flowers and seeds of the plants in spring; in addition to the leaves, flowers of the plants, Tragopan caboti mainly eat berries in summer; Tragopan caboti only eat the fruits of the plants in autumn; Tragopan caboti mainly eat the fruits and seeds of the plants which fell to the ground and eat the leaves and roots of the plants etc.3. In order to avoid the fragment of the habitat, we must adopt more scientific method to transform the artificial coniferous forests.the bamboo to the mixed stand of conifer and broad-leaved trees, to improve the habitat environment, to promote the recovery and development of the Tragopan caboti's wild population.
