These shapefiles represent the spatial distribution of mean annual groundwater recharge, in inches, for Kauaʻi, Oʻahu, Molokaʻi, Maui, and the Island of Hawaiʻi for a set of water-budget scenarios that characterize unique combinations of drought and land-cover conditions. Two water-budget scenarios were developed to quantify the effects of severe drought and future climate conditions on groundwater recharge for each island as follows: (1) rainfall conditions representative of the driest conditions during 1920–2012 and 2020 land cover, and (2) rainfall conditions representative of the driest conditions during a future dry-climate condition and 2020 land cover. Each drought condition was combined with two hypothetical...

The Owl Creek elk herd, with 7,500–8,500 wintering elk, inhabits the northwest corner of the Wind River Reservation, traversing habitats along the Absaroka Range and the Owl Creek Mountains (fig. 36). The herd contains resident and migratory elk; migrants travel an average 10.7 mi (17.2 km) one way. Elevations range from 6,000 ft (1,829 m) at Wind River near Crowheart to 12,200 ft (3,700 m) in the Absaroka Range, and summits in the Owl Creek Mountains reach 8,000–9,800 ft (2,438–2,987 m). Habitats range from sage and desert scrub in the lowlands surrounding the Wind River Range to upland meadows, aspen groves, Pinus contorta (lodgepole pine) forests, and alpine tundra. When on the Wind River Reservation, the elk...

Most of the Southeast mule deer herd winters along the Owyhee River in regions containing sagebrush communities and Columbia Basin grassland mixed with non-native annual grasslands. These mule deer either migrate west to summer ranges on Road Canyon and Gravel Ridges or east to the Owyhee Mountains along the Idaho border, with one mule deer migrating as far as Bald Mountain, 38.3 mi (61.6 km) into Idaho. Summer ranges feature shrubland, Columbia Basin grasslands, western juniper, and evergreen forests. In 2014, the Buzzard Complex fires burned 398,596 acres (161,306 ha), including Road Canyon, allowing medusahead and other non-native grasses to invade areas with originally low perennial plant abundance. Five mule...
Moose in the Jackson herd make an elevational migration in the southern portion of the Greater Yellowstone Ecosystem. This small herd of approximately 500 animals winters primarily in the Buffalo Valley just east of Jackson Lake. During migration, animals travel an average one-way distance of 33 miles, with some animals migrating as far as 67 miles. In the spring, most moose migrate north into the Teton Wilderness or the southern extent of Yellowstone National Park. Summer ranges consist of a mix of conifers and riparian habitats along the upper watersheds that flow into the Snake River. Nearly all moose in this herd are migratory, with the herd sharing a common winter range then branching out in the spring to summer...

The Likely Tables herd contains migrants, but this herd does not migrate between traditional summer and winter seasonal ranges. Instead, much of the herd displays a nomadic tendency, slowly migrating north for the summer using various high use areas as they move. Therefore, annual ranges were modeled using year-round data to demarcate high use areas in lieu modeling specific winter ranges. A high use area being used during winter by many of the collared animals is west of the Warner Mountains, east of U.S. Highway 395, and north of Moon Lake. Some animals live in the agricultural fields west of U.S. Highway 395. There appears to be little if any movement across the highway, which is fenced on both sides in this...

The Clear Lake herd contains migrants, but this herd does not migrate between traditional summer and winter seasonal ranges. Instead, much of the herd displays a nomadic tendency, slowly migrating north, east, or south for the summer using various high use areas as they move. Therefore, annual ranges were modeled using year-round data to demarcate high use areas in lieu of modeling specific winter ranges. The areas adjacent to Clear Lake Reservoir were heavily used during winter by many of the collared animals. A few collared individuals persisted west of State Route 139 year-round, seemingly separated from the rest of the herd due to this highway barrier. However, some pronghorn cross this road near Cornell and...
Elk within the Clarks Fork herd migrate though some of the most rugged and remote terrain in the lower 48 states. The herd, which numbers around 3,000, winters in the Sunlight Basin and the Absaroka foothills just west of Cody, WY. Winter ranges are a mix of sagebrush hills and lodgepole pine forests, within expansive private ranchlands. During migration, animals travel an average one-way distance of 33 miles, with some animals migrating as far as 67 miles. Spring migrations off of winter range head west towards Yellowstone National Park, up several drainages that flow out of the Absaroka Mountains, including the Clarks Fork of the Yellowstone, Crandall Creek, and smaller creeks to the south. Summer ranges consist...

The Spring Mountains are critical habitat for the Spring Mountains mule deer herd in southern Nevada. The Spring Mountains west of Las Vegas, Nevada range in elevation from low meadows at 3,000 ft (910 m) to Charleston Peak at nearly 12,000 ft (3,632 m). Lower elevations are dominated by desert scrub and shrubland transitioning to Yucca brevifolia (Joshua tree) and pinyon-juniper forest at midelevations, with mixed montane conifer including ponderosa pine and Pinus longaeva (bristlecone pine) pine at higher elevations, and sparse alpine grasses and forbs above the tree line. The migratory behavior of the Spring Mountains mule deer herd is variable, with a mix of year-round residents and short-distance elevational...

The Klamath Basin mule deer herd contains an estimated 10,775 deer and features a mix of resident and migratory animals. Most winter ranges are adjacent to the California border near Bly and Lost River, California, in areas featuring western juniper, low shrublands, and early shrub-tree habitat. In spring, these mule deer either migrate northwest to regional national forest lands or northeast past South Fork Sprague River. Summer ranges contain ponderosa pine, mixed-conifer, and early shrub-tree habitat along with alfalfa and other agricultural crops. Notably, one mule deer migrated southeast into California near Goose Lake in May 2019 and spent a year near Deadhorse Reservoir before returning to Oregon in November...

The Area 17-Toiyabe mule deer herd inhabits the Shoshone Mountains and Toiyabe Range, which run north to south in central Nevada (fig. 11). Mule deer from the Shoshone Mountains and Toiyabe Range are characterized by short distance migrations from high elevations above 7,874 ft (2,400 m), down to 5,577 ft (1,700 m). Since the 1920s, the lower elevation slopes east of Toiyabe Dome, between Wisconsin Creek and Broad Creek and locally known as Toiyabe bench, have been documented by the Nevada Department of Wildlife as crucial mule deer winter range. Because of the value of this habitat for mule deer, the BLM closed the area to domestic livestock grazing in 1983 (Nevada Department of Wildlife, 1985). In 2018, in collaboration...

Most of these data were collected in order to create a database of tree locations for use in calibrating remote sensing tools and products, particularly dead tree detection tools and canopy species maps. Data include tree locations, species identification, and status (live, dead, and, if dead, sometimes includes information on foliage and twig retention). They are a collection of different sampling efforts performed over several years, starting in a period of severe drought mortality. One csv table is included that shows data and validation results for an additional dataset that was used to test the NAIP derived dead tree detection model that is associated with this data release. Locations are not included for that...

The Murderer’s Creek mule deer herd winters south of U.S. Route 26 in river valleys near Canyon Creek, Murderer’s Creek, and the South Fork John Day River. The herd’s winter ranges are characterized by western juniper, big sagebrush, and Columbia Basin grassland communities, with medusahead and other non-native grasses invading lower elevations. In the spring, mule deer mainly migrate southeast to summer ranges distributed throughout Gilbert Ridge and the Aldrich Mountains, some traveling as far south as Devon Ridge and east to Ironside Mountain. Summer ranges in these areas contain mixed-conifer forests, ponderosa pine, and low sagebrush communities. A smaller portion of this herd migrates northeast in the spring,...
