| Abstract: | According to the investigation in the Xiaman Nature Reserve in Sichuan from 24 July to 17 August,1997. 269 individuals of black necked Cranes were observed and it was deduced that there should be about 407 individuals by the method of average density .The habitats for black necked cranes in Xiaman were marshes, Lakes,and Occasionally grasslands. Because of the environmental changes and human activities, the distribution areas of black necked cranes have been greatly reduced in recent years. |
| Keywords: | black necked crane population distribution habitat conservation |
