Problem The shallow groundwater of Nassau and Suffolk Counties is prone to contamination from current land-use, including agricultural, residential, and recreational. The aquifer system of Long Island is highly susceptible to human-derived contamination, in particular, because the soils and underlying sediments are generally composed of sandy, permeable materials that allow contaminants to move readily from the land surface into the groundwater below. Of increasing concern are the human-derived contaminants stemming from past and present uses of pesticides. In addition to the threat of direct runoff to adjacent waterbodies, pesticide transport through the shallow aquifer from inland sources may discharge to the...

Problem The discharge of freshwater and associated loading of nutrients and other dissolved constituents from the Long Island aquifer system to surrounding estuaries and their tributaries are increasingly recognized as critical factors in the health of these ecosystems. However, further work is needed to scientifically characterize these factors and present them to the public in an appropriate manner. Many organizations have undertaken assessments of this discharge and loading for discrete groundwater source areas and (or) receiving surface waters, applying a variety of techniques and assumptions. In part, this is because there is no delineation of recharge areas to the island’s groundwater-fed streams and estuaries...

BACKGROUND Long Island Sound has 600 miles of coastline and there are over 23 million people living within 50 miles of its shores. In response to water-quality issues and nitrogen pollution in the Sound, Congress created the Long Island Sound Study (LISS) in 1985. LISS is a partnership of federal, state, and local government agencies, private organizations and educational institutions working together to restore and protect the Sound. The USGS New England and New York Water Science Centers are partners in the LISS. These organizations also have historical and ongoing work with other partners in the LISS study region. Although historically the focus of LISS has been on water quality issues, a “Sustainable and Resilient...

The Appalachian Trail (AT), a 14-state footpath from Maine to Georgia, is a unit of the National Park Service that is cooperatively managed and maintained by the National Park Service (NPS), the Appalachian Trail Conservancy, AT Club volunteers, the USDA Forest Service, and other public land-management agencies. Upper elevation and ridge-top ecosystems, which comprise much of the trail corridor, have been impacted by and remain extremely sensitive to acidic deposition. Ridgetop soils that are often low in calcium make the ecosystems of the AT more sensitive to acidic deposition than other ecosystems. Furthermore, upper elevations tend to receive the highest levels of deposition. In areas along the AT, such...

The Mendocino mule deer herd complex is comprised of three overlapping black-tailed deer (Odocoileus hemionus columbianus) administrative herds, including Mendocino, Clear Lake, and Alder Springs. Mendocino black-tailed deer exhibit variable movement patterns and strategies, including traditional seasonal migrants, full-time residents, and multi-range migrants. Migrants move between seasonal ranges from a multitude of lower elevation areas within the North Coast Range in winter to higher elevation summer ranges (fig. XXX). Local biologists predict high-use winter ranges throughout both foothill slopes and valley bottoms. Female deer of the Mendocino herd complex exhibit both short-term (seasonal/annual) and long-term...

The Klickitat mule deer herd inhabits the Columbia Hills and surrounding terrain to the north along the Columbia River, Washington (fig. 23). The Klickitat River is the western boundary of the herd and is part of a transition zone between black-tailed deer and mule deer distributions. Habitats in the western half of the herd’s range include Quercus garryana (Oregon white oak) mixed with Abies spp. (fir), pine, or grassland species. The western half of the herd’s range comprises a mix of public and private lands, including rangeland, farmland, and the Klickitat Wildlife Area, which has protected crucial winter range since the 1950s. Sagebrush steppe is more prevalent in the eastern half of the herd’s range with Quercus...

The Colockum elk herd inhabits a mix of public and private lands northeast of Ellensburg between Blewett Pass of the Cascade Range and west of the Columbia River (fig. 35). The population ranges between 4,000 and 5,000 animals and is partially migratory, with individuals displaying a mix of resident (63 percent of analyzed individuals) and migratory (34 percent of analyzed individuals) behaviors. During winter, many elk inhabit grassland, sagebrush, antelope bitterbrush, and ponderosa pine habitats in the Whiskey Dick, Quilomene, and Colockum Wildlife Areas and the eastern reaches of the Naneum State Forest. As spring green up of vegetation nears, migratory elk travel northwest toward summer ranges in the Wenatchee...

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...

The winter ranges of the Northside mule deer herd can be broadly separated into northern and southern subgroups. The majority of the southern subgroup winters at low elevations near the John Day River in areas dominated by big sagebrush communities, Columbia Basin grasslands, and western juniper. The northern subgroup is more spatially dispersed, wintering by Cottonwood Creek, the North Fork John Day River, and the Middle Fork John Day River in ranges containing more conifer forest than those of the southern subgroup. Both subgroups summer in the same general area, migrating either northeast or southeast to reach ranges featuring mixed-conifer, Picea spp. (spruce), Ponderosa pine, and western juniper forests with...

This data release contains reference baselines for primarily open-ocean sandy beaches along the west coast of the United States (California, Oregon and Washington). The slopes were calculated while extracting shoreline position from lidar point cloud data collected between 2002 and 2011. The shoreline positions have been previously published, but the slopes have not. A reference baseline was defined and then evenly-spaced cross-shore beach transects were created. Then all data points within 1 meter of each transect were associated with each transect. Next, it was determined which points were one the foreshore, and then a linear regression was fit through the foreshore points. Beach slope was defined as the slope...

Summary: This study aims to do a thorough analysis of trends in peak streamflows on Long Island. Reliable information about the magnitude and frequency of floods is essential for flood insurance studies, flood-plain management, and the design of transportation and water-conveyance infrastructure, such as roads, bridges, culverts, dams, and levees. Federal, State, regional, and local officials need peak flow information to effectively plan and manage land use and water resources, protect lives and property in flood-prone areas, and determine flood-insurance rates, particularly in densely populated urban areas. Long Island is a regional economic driver which has experienced public health and safety issues due to extreme...

South Wallowas mule deer winter ranges are dispersed across areas of low elevation near the Idaho border. During spring, mule deer wintering north of Powder River and Pyles Canyon migrate to Catherine Creek and the Wallowa Mountains within the Wallowa-Whitman National Forest. Interstate 84 creates a complete barrier to southern movement for the South Wallowas herd. Mule deer wintering in areas near Interstate 84, Lawrence Creek, and Manning Creek are largely residents with only two migratory mule deer traveling to Little Lookout Mountain and Thief Valley Reservoir. Other mule deer reside along Snake River, which forms the Idaho border. One mule deer crosses Snake River south of the Powder River headwaters, migrating...

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 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,...
