To determine the ecological effects of highway construction and use upon Michigan woodlots and wetlands, ten sites located along a 45-mile segment of I-75 between Roscommon and West Branch were studied. These sites were examined in respect to several natural science parameters: Soils, hydrology, water quality forestry, and wildlife. The study provided an evaluation of the environmental impact of highway construction and use on the parameters measured by each research discipline. Several models for determining optimum highway location were also evaluated including the University of Georgia Model, which we modified and tested for use by the Michigan Department of State Highways and Transportation. This summary consists of extracts of a brief and pertinent nature from the individual reports written by the investigating team for each research discipline. Methodologies utilized, site descriptions, environmental impacts, conclusions and recomendations are detailed. /Author/
