The South China subspecies of sika deer (Cervus nippon) has been listed as an endangered species in the IUCN Red Data List, and is also assigned to Protection Class I in the List of Wildlife under Special State Protection as designated by the Chinese State Council. In recent years, sika deer have formed several relatively isolated populations and are distributed in parts of Jiangxi, Zhejiang and Anhui provinces. Taohongling National Nature Reserve is located in Pengze County, Jiangxi Province of China, which has been designated for the protection of wild southern sika deer. The reserve is 12 500 hm 2 in area, of which the Core Protected Zone is 2 670 hm 2 , the Buffer Zone is 1 830 hm 2 and the Experimental Zone is 8 000 hm 2. In the Experimental Zone, there is a considerable area of agricultural land with a high human population density. Highways surround the eastern, northern, and western boundaries of the nature reserve, while the southern border of the reserve is marked by valleys and creeks. The last estimated population of sika deer in the nature reserve was 365, which was thought to be the largest population of this sika deer subspecies. However, after strict protection for 30 years, the vegetation in the nature reserve has changed into evergreen broadleaf forests which is the local climax vegetation.

Siberian crane (Grus leucogeranus) is a critically endangered species and has been a bird species under second class protection. In recent years, almost the entire population winters at or very near Poyang Lake, China. Based on the annual maximum population size of Siberian crane wintering in the Poyang Lake National Nature Reserve during 1983 and 2011, we tested the correlation between population size and the climate variables of its wintering and breeding areas. The climate variables included monthly average air temperature, monthly average maximum air temperature, monthly average minimum air temperature and monthly precipitation. The results showed that the annual maximum population size of Siberian
