Fall Mule Deer Survey Completed

NDG&F Dept. Press Release

The North Dakota Game and Fish Department’s fall mule deer survey indicated fawn production in 2017 was lower than in 2016.

Biologists counted 2,548 (3,003 in 2016) mule deer in the aerial survey in October. The buck-to-doe ratio of 0.32 (0.48 in 2016) was lower than the long-term average of 0.43 bucks per doe, while the fawn-to-doe ratio of 0.76 (0.90 in 2016) was down from the long-term average of 0.91 fawns per doe.

Big game biologist Bruce Stillings said survey conditions were much warmer than normal, with nearly 50 percent leaf cover, which he said could explain the lower buck-to-doe ratio.

“And this year’s lower fawn production was expected based on the previous winter conditions, but it was still at a level able to support stable-to-increasing deer numbers, depending on the severity of the upcoming winter,” Stillings said.

The fall aerial survey, conducted specifically to study demographics, covers 24 study areas and 306.3 square miles in western North Dakota. Biologists also survey the same study areas in the spring of each year to determine deer abundance.
