Spatial Hydro-Ecological Decision System (SHEDS)
Seamlessly linking datasets, models, and decision-support systems, this website offers a suite of tools designed to help resource managers make decisions related to protecting freshwater aquatic habitat, including a stream temperature database, a visualization for identifying priority catchments, and an interactive GIS map featuring data on Eastern brook trout.

The following tools all live on the Spatial Hydro-Ecological Decision System website:
The objective of this effort was to develop tools to assist managers in protecting and restoring streams for brook trout and other aquatic resources in the face of threats such as climate change and development. The project included developing stream temperature, stream flow, and brook trout occurrence models for headwaters of the Northeast, including projections of the potential effects of climate change. The investigators worked closely with decision makers such as state water resource agencies to ensure the tools are useful.
1. Hierarchical modeling framework to account for multiple scales and sources of uncertainty in climate change predictions, and to forecast local (catchment scale) population persistence of brook trout.
2. Statistical models to predict stream flow and temperature based on air temperature and precipitation as a function of local environmental conditions.
3. Incorporation of climate change forecasts into population persistence models using ‘envelope’ of downscaled global circulation data on precipitation and air temperature.
