The Jackson moose herd inhabits an area 2,023 mi2 (5,239 km2) north of Jackson, Wyoming. The Jackson moose herd was historically abundant with a peak of 3,000–5,000 animals in the early 1990s. However, the herd underwent a dramatic population crash following the large counts in the early 1990s and continues to decline with an average count of 280 animals between 2016–2020 (Wyoming Game and Fish Department, 2022). The migrations of the northern portion of the herd were published in Kauffman and others (2020a). The southern portion of the herd, presented here, resides near Wilson, Wyoming. The southern portion of the herd is partially migratory. Many of the migratory moose move from lower elevation winter ranges along the Snake River to high-elevation summer ranges in the surrounding national forests and Grand Teton National Park (fig. 38). Winter ranges are characterized by riparian, mountain shrub, and aspen communities, and summer ranges include montane meadows and forested habitats. The Snake River corridor serves as a movement pathway between the southern and northern areas and provides an important riparian food resource. Migration distances range from <1 mi (<1 km) up to roughly 13 mi (21 km). Despite hunting season closures and a reduction in licenses, this population has not responded to management changes and continues to be closely monitored by regional wildlife management agencies. These mapping layers show the location of the Migration routes for Moose (Alces alces) in the Jackson population in Wyoming. They were developed from 43 migration sequences collected from a sample size of 14 animals comprising GPS locations collected approximately every 0.5 hour.
