The EPA Office of Research Development’s Mid-Continent Ecology Division, in cooperation with EPA Region 8, North and South Dakota and Montana, has begun an EMAP effort to assess selected resources of the UMR mainstem, floodplain and reservoirs. The objective is to contribute to the scientific underpinning for adaptive management of the UMR via improved ecological assessment and monitoring. Products will include recommended biological indicators, identification of potential stressors, stressor-condition associations, delineation of important sources of variation, development of appropriate sample designs for assessments, and ultimately, an ecological assessment of the UMR. Sample sites will be located using a stratified random design which produces unbiased estimates of resource condition with known statistical confidence. In 2000, pilot studies will focus on the Garrison Reach of the UMR (ND) and Lake Oahe (ND and SD). Initial efforts will include (1) a synoptic survey of water chemistry and sediment in the river and reservoir; (2) an assessment of the trophic status of Lake Oahe; (3) quantification of longitudinal and interhabitat variation in the riverine and reservoir macrobenthos; and (4) analysis and classification of floodplain riparian condition, including the functional significance of woody debris habitat in the mainstem.
Presented at 1:00 PM on Wednesday, May 31, 2000 in Bioassessment: Case Studies
