Justin Gude, Research and Technical Services Section Chief for Montana Fish, Wildlife and Parks, said recently: Providing the quality habitat they need on summer and winter ranges is as important as preserving connectivity between the two.. The rest of our workshops followed in Mesquite, NV, Laramie, WY, and Bozeman, MT to eventually reach 13 western states, as well as federal and tribal agencies. Being able to knit together polygons of these important movement corridors and winter ranges allows for a large-scale look independent of artificial state borders. 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. (what colors can they see? This is the Eastern Sierra - California's "Wild Side." A land like nowhere else. 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.

Caribou migrate to the south for winter. If they migrate too fast and overshoot the green up, they wont have nutritious forage or may get stuck in a late snow storm too high. Approximately $1 billion in property damage is also caused by these incidents. They were developed from Brownian bridge movement models using 117 migration sequences collected from a sample size of 54 adult mule deer comprising GPS locations collected every 2 hours. Additional migration routes and winter range areas likely exist beyond what was modeled in our output.Corridor tiers (low, medium, high) could not be computed with such a small dataset.
