Biology Environmental Science Geography stream health southeastern Ohio land use land cover forest connectivity WAP ecoregion IBI STAR For twenty years the Ohio EPA has characterized stream health using fish and macroinvertebrate community assemblages, as well as by local habitat within the stream. Since the adjoining landscape may also influence stream health, this research explores a variety of easily attainable GIS land use/cover, population, and forest connectivity data to find which best correlate with stream health. Four different metrics (percent native fish, darters/sculpins, intolerant, and sensitive species) were evaluated against forty-eight different independent variables using multiple regression. Three variables were important for predicting stream health: density of abandoned mine openings in the upstream catchment, forest connectivity in a 66 ha area surrounding the sample point, and percent wetlands (from NLCD) within the HUC-14 subwatershed. Percent forest cover (GIRAS) in the upstream riparian buffer was also important for intolerant species. Despite known macro- and micro-controls on fish communities, landscape variables were able to explain up to half the variance in these fish metrics. 2008-04-25 English text Ohio University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1206047003 http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1206047003 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
