Guidelines to drawing ecologically sound boundaries for national parks and nature reserves

Ecological approaches to drawing boundaries for parks and reserves are developed, described as 15 guidelines. The five abiotic guidelines are designed with the principle objective of maintaining drainage basin integrity. The ten biotic guidelines are designed to reduce as little as possible the natural diversity of populations in both the total natural area and in the communities directly traversed by the boundary line. Three of the biotic guidelines apply to maintaining community diversity, the remainder to species diversity. These guidelines are applied to a 2500-km² potential national park in a montane environment in the southwest Yukon Territory. They were successful in generating the conclusion that boundaries in the subalpine best satisfy the guidelines in this environment.
