Threshold Management of Resource Exploitation of the Yancheng Wetland Nature Reserve

The Yancheng Wetland Nature Reserve has to be confronted with the conflict between resource conservation and exploitation in its management and construction.Threshold management technologies of resource exploitation have been brought forward based on analysis of the needs of overwintering Grus japonensis and disturbance caused by resource exploitation.For access into the reserve,resource exploitations are sorted into three types: moderate exploitation,restricted exploitation and forbidden exploitation.The area accessible for exploitation is limited to the experimental zone,which should be kept no more than 1/10 of the nature reserve,and should not exceed 1/3 of the experimental zone in area.Based on the birds′ needs for overwintering,the time period of a year from the end of September till February of next year should be set as restricted for exploitation activities and from early March till the end of September as accessible for moderate exploitation.It is acceptable to go all out to develop ecotourism,while it is essential to ban any new project of tide flat wetland reclamation and wind energy in the reserve.
