Since 2006, state federal and tribal governments and their conservation partners have been working together across the Midwest and Great Plains to develop Fish Habitat Partnerships (FHP) under the National Fish Habitat Partnership (formerly known as the National Fish Habitat Action Plan).  Six FHPs have grown with independent missions to address a common problem, habitat degradation.  As the FHPs formed they quickly realized a shared need to understand the scope and severity of aquatic habitat degradation across the landscape.  In 2009 they jointly undertook the three year task of assessing aquatic habitat condition by modeling cumulative impacts of primarily terrestrially based anthropogenic stressors in stream and lake catchments.  This symposium will address the science behind the models, mapping products, and decision support tools being made available to fishery management organizations and others interested in aquatic conservation.  Symposium speakers will discuss the data, analysis, and results of thirty-two independent fish habitat condition modeling efforts, the challenges of such an effort, the advantages of working together, and importance of this information in making strategic fish conservation decisions at the landscape and local scales.  This foundational effort paves the way for much more investigation into the causal relationships between independent and cumulative human disturbances within watersheds and the subsequent impact to aquatic habitat and fisheries.
