Various data sources documenting urbanization and industrialization were overlayed with fish and wildlife resources, habitats and other features in order to estimate impacts. Concern over wetland loss, benthic-bottom disturbances, and sediment contaminant can be quantified on a regional level so as to allow resource managers the faculty to make decisions on a comprehensive basis. Ecological risk assessments of the impact of human development on important natural resources can be developed in a systematic and comparative way. Geographic Information Systems (GIS) offer policymakers and regulatory agencies a means for managing complex and disparate databases through analytical and modeling capabilities.
