This table shows that the Great Sand Dunes Tiger Beetle was found in areas of bare sand and areas where very little grass or vegetation grows. When over 15.04% of the land was covered with vegetation, C. theatina was not found during the surveys.

Data includes four study sites, with five transects per site, for a total of 20 transects sampled.
