Mule deer range from 3 to 3-1/2 feet tall at the shoulder, 4-1/2 to 7 feet long and have a tail that is 5 to 8 inches long. They can weigh between 130-280 pounds. The female deer are smaller than the male.
Mule Deer. From 1978 through 2001 the Trans Pecos mule deer population has fluctuated from lows of fewer than 100,000 to a high of 221,220. Fluctuations in mule deer populations are normal but to manage mule deer well, we must understand the factors causing the fluctuations. Mule deer populations are calculated by Texas Parks and Wildlife biologists through 945 miles of aerial transects and 393 miles of spotlight surveys.
