A method is described of applying institutional arrangements to an individual environmentally significant area (ESA). It is assumed that an ESA has been recognized by park, wildlife, or other groups, on the basis of abiotic, biotic, and/or cultural, characteristics, as well as judgements about significance and constraints. National park, wildlife reserve, or other, institutional arrangements, may also have been suggested for the ESA. The goal is to decide whether these or other arrangements are appropriate— through analysis of relevant: (1) legislation; (2) agencies; and (3) reserve designation or land management types.
