Density Disturbance Calculation Tool
The Density and Disturbance Calculation Tool (DDCT) is a spatially based application that calculates the number of disruptive activities averaged per square mile and the percentage 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.
Exception requests for seasonal timing limitation stipulations may be submitted via the DDCT or can be submitted to wgfd.hpp@wyo.gov using this form.
If you have technical questions about using the DDCT application, please contact the GIS DDCT Support team at 307-757-0408 or via email at WGF-one-steppe-admin@wyo.gov
If you have questions about the policy or biology that underlies the DDCT process, please call the Habitat Protection Program at 307-777-4506 or email us at wgfd.hpp@wyo.gov

You can upload a zipped shapefile of your project into the Natural Resource and Energy Explorer (NREX) to determine where your project is in relation to Sage Grouse Core Areas.
Please keep in mind that the Sage-Grouse Executive Order applies to Non-Core Population Areas. NREX can also be used to determine if your project is within the buffer of a non-Core lek.

Answer
The Sage Grouse Executive Order does have some limitations with regards to Non-Core Population Areas. Uploading a shapefile of your project to the Natural Resource and Energy Explorer (NREX) tool will help you to determine if your project is within the 2-mile timing stipulation buffer of a non-Core lek, or the .25-mile No Surface Occupancy buffer of a non-Core lek.
