Habitat / Sage Grouse Management / Density Disturbance Calculation Tool

Density Disturbance Calculation Tool (DDCT)

The Density and Disturbance Calculation Tool (DDCT) is a spatially based application that calculates the number of disruptive activities averaged per square mile and total surface disturbance within the DDCT assessment area.  Proponents of surface disturbing activities in sage-grouse core areas must submit their project footprints through this tool to complete their permitting process. If you need assistance to determine if your project is in a core area, please use the Natural Resource and Energy Explorer tool.

Please use the following links to access the web application and DDCT worksheets.
