Behavioral fragmentation of waterfowl habitat and its landscape ecological design in Shuangtai-hekou Reserve, Liaoning, China

--Behavioralfragmentation of wildlife habitat isdiscussed. Using "buffer" module inARC/INFO, behavioralfragmentation habitat of Red-crowned crane, Saunder's gull,Orientalwhite stork and Siberian white crane was calculated in theShuangtai-hekou nationalreserve, Liaoning Province, China. Theresult showed that breeding Red-crowned crane,Siberian white craneand breeding Saunder's gull are very sensitive to fragmentfactors.Suitable habitat is so little for more than 2000 Saunder's gull tobreed. Thereserve only has a capacity of 38 pairs for breedingRed-crowed crane. Two key measureswere made. First, dismantles allthe abandoned oil wells and recovers the originalecosystem todecrease the fragmentation effect, directly benefit to breeding ormigration ofRed-crowned crane and Oriental white stork. Second,recovers the Suaeda tidal mud flat fromartificial shrimp and crabpond in the kernel zone of the reserve to enlarge the habitatareaof Saunder's gull and Siberian white crane.
