The Distribution, Habitat Quality And Conservation Status Of The Endangered Teinopalpus Aureus In Jiangxi

Teinopalpus aureus is the world’s endangered butterfly species and protectedspecies of grade Ⅰ. This paper had collected the distribution data(the distribution area,the occurrence sites, etc.) of endangered Teinopalpus aureus in Jiangxi Province by fieldsurvey, combined with the data of each distribution area which obtained from remotesensing, land utilization and forest resources management survey, analyzed theenvironment (topography, vegetation, etc.) and landscape characteristics(landscapecomposition, landscape index, etc.) of each distribution by the3S technology. This paperrevealed the occurrence characteristics of the endangered species and its specialrequirements on terrain, vegetation and other habitat resources, to realize the habitatfragmentation status, human disturbance factors, and habitat conservation status of eachdistribution area, to provide a reference for the protection of the species. The mainfindings were as follows:(1) The field survey confirmed Teinopalpus aureus had4distribution areas in Jiangxi,respectively Jinggang mountain, Wuyi mountain, Jiulian mountain and PS(This localityhadn’t been publicly reported, and had no habitat protection measure. So taking into theneed of protecting the species, the geographic name was represented by the letters in thispaper), and found that the butterflies occurred rarely in each distribution area, which hadonly1-3occurrence sites.(2) The endangered butterfly had specific requirements on terrain, vegetation andother habitat resources through analyze the environmental characteristics of Teinopalpusaureus occurred. On the terrain, the butterfly mainly distributed in the regions the altitudemain of600m to1200m. The highest elevation of the distribution areas was above1200m, which were the typical middle mountainous terrain. The distribution areas of butterflyshowed a high overlapping features with natural forest area (especially evergreenbroad-leaved forest), indicated that the natural forest area is an important habitatresources. The survey also found that the occurrence of field sites were in the naturalforest area.(3) Landscape pattern analysis showed the number of domicile, farmland, artificialconiferous forest, artificial broad-leaved forest landscape types patches in variousdistribution areas were larger. This patches distributed separately and showed the highdegree of habitat fragmentation. Relatively speaking, the Jiulian mountain and Wuyi mountain in the four distribution areas were more appropriate for the Teinopalpus aureus’s life.(4) Human activities had been directly or indirectly caused the disturbance toTeinopalpus aureus habitats, and it had been seriously affected the Teinopalpus aureushabitats’ distribution. To the habitat area of various interference factors of the habitatdisturbance factor the ratio of total area that the most serious interference was Jinggangmountain, which accounting for50.07%. The ratio of other districts were PS41.39%,Wuyi mountain35.27%, Jiulian mountain27.46%. Jinggang mountain and PSinterference were serious, which need for timely protective measures.(5) To comparing four distribution areas with the local nature reserves, we found adifferent distribution area protected by the current situation which was very different. Inaddition to most of the area of Jinggang mountain distribution area was natural protectionarea, However, most of the other three regions of the distribution area were in a state ofdisorder unprotected, not even protected areas. At present the conservation was an urgentwork.
