Mule Deer - Baggs. Winter range designations for this herd would likely expand with a larger sample, filling in some of the gaps between winter range polygons in the map. The overall population of deer will be relatively low when compared to other areas, and the animals will be scattered around solid food and water sources.

While hunting with specialized, large caliber pistols is not as popular as the other methods, it does require the same amount of patience and skill as a muzzleloader or archery equipment as you must be very close to a deer in order to make an accurate shot. By producing maps of these movements, managers can illustrate quite vividly why these habitats are important and work to resolve the problem areas. Resident deer with winter ranges overlapping those of migrant deer were removed from the analysis; only migrants were used in the mapping of corridors, stopovers, and winter ranges. The vegetation along the sides of the roadway is mowed increasing the site distance of the driver. Thirty-six migration sequences from 9 deer, with an average migration time of 19.53 days and an average migration distance of 87.57 km, were used from the 2017-2020 dataset.

Highway 395 is a major barrier to migration, with hundreds of deer being killed annually trying to cross it. Timing their seasonal journeys to take advantage of the most nourishing vegetation, these herds must migrate across vast expanses of public and private lands to maintain viable and productive populations. Such impacts on the population can affect viability of the herd, particularly when combined with habitat loss and degradation.

Large numbers of deer are on the move at this time of the year and they pose a real threat to motorists. In addition, a Corridor Mapping Team is being coordinated and funded by the U.S. Geological Survey in collaboration with state wildlife biologists, resulting in a diverse team with strong computer mapping skills to work with the millions of animal coordinates flowing into agencies westwide from many thousands of GPS radio collars slung around the necks of mule deer, elk, and pronghorn.

The first step in the conservation of big game corridors is to identify these movements and the multitude of things that interfere with them.
