Abstract : These general guidelines for developing wildlife community habitat models will provide Corps field biologists with an improved understanding of applications of the principles of community ecology. These guidelines meet the need of the field biologist under Section 404 of the Clean Water Act to prevent or mitigate for habitat impacts to wetlands by aiding in the assessment of models to evaluate wildlife community habitat value under different spatial scales. This document provides guidance on using species-area relationships to develop wildlife community habitat models. Establishing clear wildlife resource objectives is important prior to model development. Different measures of species richness can be used to meet different objectives. Species-area curves can be used independently or with either spatial or habitat modifiers. The use of spatial or habitat modifiers improves the power of the species-area relationship in predicting species richness. Limitations of using the species-area relationship include the possibility of overlooking the value of small areas for certain species and the difficulty in considering the effects of regional dynamics on species richness.
