Although much research has been undertaken to design nature reserves, there
are few practical methods to determine the interior structure of a reserve
. A procedure for design of the core zone in reserves is proposed. As a cas
e study, the core zone in Yancheng Biosphere Reserve, People's Republic of
China, which was established to preserve the endangered red crowned crane (
Grus japonensis) is designed. A statistical habitat model using geographic
information system (GIS) is developed to predict crane presence or absence.
Based on predicted suitable habitats, the minimum core zone is defined. Mo
re suitable habitats can be contained in the designated core zone, and this
will be beneficial to the conservation and restoration for crane habitats.
