Selection and Plant Community Characteristics of Foraging Sites for Hume’s Pheasant (Syramticus humiae) in Nanhua Part of Ailaoshan National Nature Reserve

  • Plant communities of foraging sites of Hume’s Pheasant (Syramticus humiae) had been surveyed by systematic sampling method since April 25 to May 16, 2008 in Nanhua part of Ailaoshan National Nature Reserve. And 133 plant species were recorded, belonging to 86 genera and 49 families. The results by spearman correlation analysis showed that there was a significant relativity between occurrence frequency of S. humiae and distribution of evergreen broadleaf forest, which meant the vertical distribution and territory of the birds were affected by the distribution of evergreen broadleaf forest. S. humiae preferred to select evergreen broadleaf forest as habitats. The results by important value ordination of plant and detrended correspondence analysis showed that the plant composition in foraging sites was conformed to evergreen broadleaf forest whereas greatly different from other forest types. The composition among plant layers in evergreen broadleaf forest could provide preferable coverage, either leaves or stalks of pteridophyte and nuts of fagaceae were foods for S. humiae. The results of diversity comparison showed that plant diversity in foraging sites were significantly higher than Pinus armandii forest and deciduous broadleaf forest because both forests lacked vegetable foods. So habitat selection of Hume’s pheasant was affected by plant diversity and food richness. The results by comparison of vegetation factors and detrended correspondence analysis showed that tree coverage in foraging sites were higher than other forest types except evergreen broadleaf forest. The degree of similarity in foraging sites and other forest types differed. Deciduous broadleaf forest was less similar to foraging sites in vegetation factors where trees were sparse and S. humiae liked to graze greatly. There were short trees and few shrubs in P. armandii forests. However, mixed broadleaf and coniferous forest were more similar to foraging sites in vegetation factors, where human disturbance was serious. Coverage and human disturbance were dominant factors that influenced foraging sites selection of S. humia. The results by analysis of dissimilarity showed that the most studied area could supply basic conditions for the survival of S. humiae but the best suitable area was less indeed.
