      Learn more about each HRVA/SARA used in our products

      Highly Valued Resources or Assets (HVRAs) or Strategic Areas, Resources, and Assets (SARAs) are landscape features that have societal value and can be influenced positively and/or negatively by fire. Each HVRA or SARA has a footprint across your landscape as well as response functions (RFs) to disturbance (wildfire) and management. The list of HVRAs/SARAs on this list represent what is available by default or as an upgrade across Vibrant Planet products. Many HVRAs/SARAs have Forest Vegetation Simulation derived response functions to disturbance and treatment. You can learn more about the data used to generate those footprints and RFs for each SARA below:
