Project Tools

• ETAC. Software for Calculating Vegetation Disturbance and Recovery by Using the Equivalent Clearcut Area Model. Calculating ECA on multiple watersheds and management scenarios for project-level analysis is a tedious process. We automated the process with a program called Equivalent Treatment Area Calculator (ETAC) to streamline its application on National Forests in the Blue Mountains of Eastern Oregon.
