The preliminary study on foraging habitat of Red-crowned Crane in autumn in Honghe Nature Reserve

Foraging habitat of Red-crowned Crane in Autumn was investigated by factor determined in Honghe Nature Reserve from Oct.12-21,2005.The height,density and coverage of the vegetation,the depth of water,human disturbance and other factors in their habitat were measured.Foraging habitat of Red-crowned crane is also measured by quadrate methods.According to the measurement,the paper compares the foraging habitat of Red-crowned Crane in Honghe Nature Reserve.The result show:the coverage of the vegetation is 49.50%,the density was 491/m2.The data was analyzed by variance and average value compare and other mathematics methods,then get the result:they prefer the foraging habitat that height of the vegetation 60-120cm,coverage lower 75%,density lower 600/m2 and active in the habitat that human disturbance was over 500m.The research can provide some data for their conservation.
