Case study that demonstrates how readily available downscaled climate change and land use development models can be incorporated into species distribution models to characterize potential future changes in aquatic conditions to better inform long-term conservation and restoration planning at the catchment level.

The top five anthropogenic and top five natural variables from each model for each FHP and a regional model are summarized in this brief. This summary pinpoints only those variables that were most important in structuring the responses for each model. Across all models, each variable is tabulated for the number of times it is occurs as one of the most influential (top 5 of each category). This analysis presents the relative usefulness of the most important variables in structuring regional- and fhp-scale model responses

Recent modeling efforts at the regional and FHP scale have indicated that smaller-scale models are likely necessary to pinpoint localized stressors. From discussions with experienced modelers and fishery professionals, HUC8 watersheds were agreed upon as the most appropriate scale.
This report summarizes a case study that demonstrates the effect of scale on the assignment of stressors from predictive BRT models. Specifically, we modeled the same response at three different scales and for two separate HUC8 watersheds

Downstream Strategies is committed to a stakeholder-driven process to guide each phase of this project, we propose the following methodology as a potential template for much of the work for inland stream modeling. It is not our intention to dictate the process, but inform the NALCC stakeholders about a generalized methodology that has shown to be useful in the past, and that could be implemented for this project, should the stakeholders find that it would meet their objectives and expectations.
