Projects

The Climate Shield website hosts geospatial data and related information on specific locations of cold-water refuge streams for native cutthroat trout and bull trout across the American West. Forecasts about the locations of refugia could enable the protection of key watersheds, be used to rally support among multiple stakeholders, and provide a foundation for planning climate-smart conservation networks that improve the odds of preserving native trout populations through the 21st century.
Climate change is projected to alter the flow regimes of streams and rivers, with consequences for physical processes and aquatic organisms. Our stream flow dataset makes it possible to study the effects of droughts, changes in snowpack, water resource impacts, and other hydrologic changes under historical and future climate change scenarios.
In the interior West, western spruce budworm outbreaks often last for decades, but their impact on fire behavior is poorly understood. By isolating the effects of the insect on a single tree and simulating the tree in a three-dimensional fire model, researchers were able to identify precise links between western spruce budworm disturbance and fire behavior changes.
Tree-rings are used to reconstruct fire and forest histories in central Oregon.
Spatial statistical models for streams provide a new set of analytical tools that can be used to improve predictions of physical, chemical, and biological characteristics on stream networks. The Spatial Tools for the Analysis of River Systems (STARS) and Spatial Stream Network (SSN) models are unique because they account for patterns of spatial autocorrelation among locations based on both Euclidean and in-stream distances
Thermal regimes are important to aquatic ecosystems because they strongly dictate species distributions, productivity, and abundance. The stream temperature modeling and monitoring web site provides resources to help those in the western United States organize temperature monitoring efforts, describes techniques for measuring stream temperatures, and describes several statistical models for predicting stream temperatures and thermally suitable fish habitats from temperature data.
On July 30, NASA selected the Global Ecosystems Dynamics Investigation (GEDI) LiDAR mission for funding under its Earth Venture Instrument-2 program. A full-waveform LiDAR instrument will be attached to the International Space Station (ISS) and will provide unprecedented detail about the structure of the world’s forests.
In the effort to use genetically appropriate plant materials for restoration projects, provisional seed zones were developed as one method of pairing seed sources to restoration sites.  Provisional zones were developed through grouping similar climate parameters across broad geographic areas without regard to species specific performance or genetic information. As such, they function as a tool for identifying similar climate envelopes which may serve as an acceptable interim surrogate for species specific genecological work in pairing seed sources to restoration sites. 
The Interior West Forest Inventory and Analysis (FIA) Program collects increment cores as part of regular monitoring. Ring-widths from these increment cores are being digitized and assembled into data products for biogeographical or climatological analyses. 
The objective of this project is to quantify seasonal patterns of carbon fluxes in two dominant marsh types in the Florida Everglades: short- and long- hydroperiod Everglades marshes.
