1. Muley Fanatic Foundation - MFF is a hard working mule deer centric organization originating out of Wyoming. It now has chapters in Wyoming, Utah, Colorado, and Idaho. Their mission is as follows:

To ensure the conservation of mule deer and their habitat and to provide such supportive services to further the sport of hunting and sound wildlife management.

A recent achievement of this organization is its strong leadership in lobbying the Wyoming Legislature to pass a Wyoming Conservation License Plate Bill. This license plate is purchased at the choice of the motorist. Extra fees are assessed to these plates that will go to a fund for solutions (ie wildlife overpasses) that reduce or alleviate wildlife vehicle collisions.

2. Wyoming Migration Initiative - WMI has unlocked some of the greatest migrations on earth, including a 240 mile one-way mule deer migration from Southern Wyoming to Idaho. Their work has led to several solutions to decrease migration barriers, increase habitat conservation, and reduce animal-vehicle mortality. Their mission is as follows:

Advancing the understanding, appreciation, and conservation of Wyoming's migratory ungulates by conducting innovative research and sharing scientific information through public outreach.

3. Western Association of Fish and Wildlife Agencies Mule Deer Working Group

"In 1997, the Western Association of Fish and Wildlife Agencies (WAFWA) established a Mule Deer Working Group (MDWG) consisting of a representative from each western state and western Canadian province. Since the time of the MDWG’s inception, it has been successfully addressing mule and black-tailed deer concerns shared among wildlife agencies in western North America."

"The purpose for this working group is to:

  • Begin to develop strategies to assist in management of declining mule deer populations throughout the West;

  • Improve communication among mule deer biologists throughout the West;

  • Provide a forum to respond to information needs from agency administration. "

Other organizations doing big things for mule deer and all wildlife include: The Nature Conservancy (, the National Wildlife Federation and its affiliates, two of my favorite NWF affiliates are: Wyoming Wildlife Federation ( and Artemis (, and Backcountry Hunters and Anglers (
