Developed by The Nature Conservancy Eastern Division. Permeability, rather than being based on individual species movements, is a measure of landscape structure, incorporating the hardness of barriers, the connectedness of natural cover, and the arrangement of land uses. - See more at: http://bit.ly/18eOPIU

File December 2019: SHEDS Applications Beyond New England
This presentation by Dr Jeffrey Walker (USGS, UMass-Amherst) explores the capabilities of Interactive Catchment Explorer spatial applications beyond New England. Current projects include tracking movements of PIT-tagged fish, evaluating ecological benefits of culvert and dam improvements, assessing vulnerability of endangered fish, and a streamflow alteration study. The presentation contains links to each interactive tool.

File D source code December 2019: Stream Grade Considerations for Epoxy Anchor Method
Many of our temperature loggers have been lost due to ice scour. This presentation by Kirstin Underwood (USFWS) briefly explores and analyzes stream grade considerations for the epoxy vs chain anchor method.

File Midwest and Great Plains Assessment Models Data Summary
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

File Case Study: Analysis of scale on boosted regression tree fish habitat models
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

File Preliminary Framework Concept: Inland fish habitat modeling for the North Atlantic Landscape Conservation Cooperative
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.
