ForSys is a flexible platform for exploring landscape management scenarios and optimizing decisions in terms of where and how to achieve landscape restoration and fuel management goals. The model is spatially explicit and uses multi-criteria prioritization and optimization created to rapidly design fuel treatment and restoration scenarios.
The USDA Forest Service Scenario Investment Planning Platform was developed by Forest Service Research & Development to help the agency modernize its approach to prioritizing land management investments. 
The National Ecosystem Services Strategy Team collaboratively develops and integrates ecosystem services into Forest Service programs, policies, and operations. This work elevates the agency mission by identifying the breadth of benefits that forests and grasslands provide, analyzing the impacts of our decisions on these benefits, and inviting a diverse set of partners to ensure their sustained delivery.
Firesheds are a way to delineate where fires ignite and are likely to, or not to, spread to communities and expose buildings. The fireshed map shows the source of exposure to fire. The fireshed registry is the geospatial portal that portrays the past, present, and future in terms of agency investments in forest and fuel management in relation to historical and predicted fire activity.   
Seed germination is a critical step in the life history of plants. The seeds of many arid land plants delay germination until the seeds receive environmental cues that stimulate them to grow. These dormancy-breaking cues may vary among populations of the same plant species, depending on their local environmental conditions, and can determine the selection pressures experienced during plant growth and establishment.
We are developing a product and methodology that allows rapid assessment of fuels and potential fire hazard in forests impacted by the non-native balsam woolly adelgid (BWA) to better protect and improve the health of western America’s high-elevation fir forests. We will 1) compare fuel metrics derived from standard field procedures with aerial and terrestrial lidar-derived fuel metrics and 2) use physics-based fire behavior models to simulate...
Using destructive samplings methods and a Leica BLK360 terrestrial lidar scanner (TLS), we measured and scanned 20 small diameter trees before breaking them down for accurate volume measurements. We then compare our lab-based results to the 3D quantitative structure model output retrieved from inputting our point clouds into TreeQSM code.  
Opportunity and Vision
Lick Creek Demonstration-Research Forest: 25-year fire and cutting effects on vegetation and fuels.
Researchers and managers have partnered to create cutting-edge, high-resolution, high-accuracy maps of Mexican spotted owl habitat - as well as long-term habitat trends - that can be updated annually as new data become available. An interactive Google Earth Engine experimental app allows end-users to explore mapped products.
