Climate change will have sweeping impacts across the Northeast, yet there are key gaps in our understanding about whether species will be able to adapt to this changing environment. Results from this project will illuminate local and region-wide changes in forest ecosystems by studying the red-backed salamander, a species that is a strong indicator of forest conditions. This study identified habitat and forest characteristics that improve the resiliency of forest dwelling amphibians and other wildlife to climate change. Further, by studying a foundational species in forest floor ecosystems, the scientists can use the information to make inferences about rare and declining species. The researchers studied multiple...

The USGS Southeast Ecological Science Center (SESC) Nonindigenous Aquatic Species (NAS) database provides records of sightings and capture data of non-native (introduced) aquatic species over the entire the United States (Benson 1999). For areas within the SALCC region, the NAS currently contains records dating back to 1885 for over 200 nonindigenous plant and animal species. This project seeks to utilize these data along with new GIS-based data on current and future (e.g. SLEUTH) landscape and climate parameters to develop models of invasive species introductions and dispersal across the SALCC region. Both multi- and single species models will be considered in these analyses. We will then utilize a formal decision-analytic...

Unconventional oil development in the Bakken shale region has increased rapidly as a result of new technologies. This region also supports a particularly high density and diversity of grassland bird species, which are declining across North America. We examined grassland bird response to unconventional oil extraction sites (i.e. developed with hydraulic fracturing and horizontal drilling) and associated roads in North Dakota. Our goal was to quantify the amount of habitat that was indirectly degraded by oil development, as evidenced by patterns of avoidance by birds. Grassland birds avoided areas within 149 m of roads (95% CI: 4 – 294 m), 267 m of single-bore well pads (95% CI: 157 – 377 m), and 150 m of multi-bore...

FY2013The increase in large wildfires at a time when habitat for Greater Sage Grouse and other species dependent on big sagebrush has also increased has led to substantial needs for big sagebrush seeds. Significant decisions on which sagebrush seed to use and on management treatments that affect competing herb layers on the same restoration sites affect the trajectory of habitat.This project will evaluate how seed source, specifically genotype and climate-of-origin, interact with landscape-scale and replicated treatments (fencing, herbicide application, mowing, and seeding).

Resource managers must balance the impacts of competing management decisions on multiple, interacting natural systems. Hydrologic and ecological processes, such as groundwater fluctuations and riparian evapotranspiration, can be tightly coupled. Ideally, managers would have tools and models that include all processes to better understand how each management action would propagate through the environment. Because resources are limited, management tools that include only the most important processes may be more realistic. However, in some cases, omitting some interactions can lead to significant errors in predictions of hydrologic outcomes and ecological function, severely limiting a manager’s ability to identify...

For the Upper Yukon area of interior Alaska, climate change has become a daily fact of life, causing a wide range of impacts to the environment, and in some cases to community health. In 2015 the Alaska Native Tribal Health Consortium and the Alaska Climate Adaptation Science Center organized a series of assessments to better understand the impacts of climate change being observed in this region, including the communities Arctic Village, Fort Yukon, and Venetie. Support for this project was provided by USGS and by local tribal partners including Arctic Village Traditional Council, Gwichyaa Zhee Gwich’in Tribal Council, and the Venetie Village Council. The assessments were also performed in partnership with three...

This project was designed to use climate models to produce projections of changes in sea temperatures and ocean chemistry for coastal marine areas in Micronesia as well as reports that describe the outlook of culturally important marine sites in Guam and CNMI. The projections and maps were expected show what the current state of climate science suggests the future holds for marine areas in Micronesia if we continue to use fossil fuels aggressively. These projections of sea conditions will become the foundation of outlook reports for Tumon Bay in Guam, Lao Lao Bay and Saipan Lagoon in Saipan, and northern Tinian Island. The selected areas are among the most important sites for recreation in Guam and CNMI and, as...

Small Pacific islands are especially vulnerable to climate change. Challenges these coastal communities face include sea level rise, erosion, saltwater intrusion, flooding, droughts, and coral bleaching which in turn affect food and water security, infrastructure, and the health of humans and ecosystems. These small islands also have limited resources; therefore, managing them effectively is important to ensure sustainable communities and healthy environments. To support natural resource management, accurate, detailed, up-to-date geospatial data and products are vital to help monitor these resources, identify potential threats, and reveal potential solutions. Through this project, the University of Guam (UoG)...

Marine and inland fisheries provide substantial economic, nutritional, recreational, and cultural benefits to human populations globally. Though extensive research and management efforts exist to ensure the sustainability of these important resources, many fisheries still face threats including climate change, habitat degradation, and overfishing. The inland fisheries community often cites that less attention is given to inland fisheries compared to marine but, to date, no quantitative analysis has examined these differences. Our goal is to compare investment and resources allocated to the research and management of marine and inland fisheries relative to their value at a global scale. Through the development of...

Climate and land use change will strongly affect tropical island ecosystems and trust species (like migratory birds and threatened and endangered species). The risks of significant negative impacts are likely to be higher in these island systems than in many temperate regions of the world because of the limited size of their land masses, high numbers of species that only exist in narrowly defined regions, and expectations that tropical environments will experience greater changes in temperature. Tropical island communities are faced with making important decisions related to adaptation that could impact the health of important natural resources and ecosystems. However, a lack of scientific guidance and information...

Partnerships - Atlantic Coastal Fish Habitat Partnership, Reservoir Fish Habitat Partnership, and Southeast Aquatic Resources Partnership Almost 10,000 ft (over 15,000 plantings) of native mangrove and salt marsh plants, as well as oyster shells were put in the Atlantic-side estuaries of Florida. These plantings helped to stabilize sediment and shoreline, improve water clarity, provide nesting areas for birds such as the Roseate Spoonbill, and provide habitat for species such as Red Drum, Tarpon, Mangrove Snapper, and snook. In addition, five acres of invasive Brazilian pepper trees were removed to allow for native plantings. Fish Habitat Partnerships provided funding for: the creation of 750 acres of wetland,...

Urban areas significantly and negatively affect aquatic habitat quality in the Mountain States. This was particularly apparent in the rapidly growing Denver/Ft. Collins, Boise, Salt Lake City, Great Falls, and Billings areas. Highway corridors along Interstates 25 and 90 in Wyoming and 76 in Colorado were implicated to be causing high to very high risk factors. In 2015, the highly urbanized I-25 corridor between Cheyenne, WY and Pueblo, CO had a population of 4.49 million people. In these cities and their surrounding suburbs, large areas of impervious surfaces (i.e. buildings, parking lots, and roads) replace natural streamside habitat, increase pollution and sedimentation, alter hydrology, and increase the demand...

A greater percentage of Alaskan residents fish (53 percent in 2011) than residents of any other State. Alaska’s largest private sector employer is commercial fishing with total annual landings of fish products of 79 billion pounds (36 million metric tons). Nearly all of these fish are from self-sustaining populations. In 1867, the United States Secretary of State William H. Seward offered Russia $7,200,000, or two cents per acre, for Alaska. The State of Rhode Island could fit into Alaska 425 times. Most of America's salmon, crab, halibut, and herring come from Alaska. The State's coastline extends more than 6,600 miles. Alaska is the largest State in the United States and is more than twice the size of Texas.

A major hub for manufacturing and transportation, the Great Lakes and their tributaries were once an easy dump site for their waste products that included organic toxins, mercury, PCBs, and dioxins. As a result of the Federal Clean Water Act (1972) most of the direct pollution discharges from known point sources have stopped, but the legacy pollutants remain because many are trapped in lake and stream sediments. Other dissolved pollutants have long residence times because less than one percent of the water in the Great Lakes exits the lake system annually. Discharge from sewage treatment systems remains a problem, particularly where stormwater and sewage systems are combined in large urban areas. The inland fish...

A significant number of dams are located in Iowa (> 4,000), Illinois (> 1,759), Indiana (> 1,088) and Ohio (> 2,600). Dams in the Central Midwest were built to provide mechanical power for mills, hydropower, recreation, water supplies, and water retention for urban and agricultural use. Nearly all of these dams impede fish movements in the region and particularly in the Mississippi River drainage and in the watershed of lakes Erie and Michigan. Some communities are removing dams to deal with obsolete infrastructure issues and to improve water quality, flow, and stream connectivity. For example, the removal of Black Berry Creek Dam near Aurora, Illinois in 2013 opened up 32 miles of the Fox River for fish spawning...

The saltwater triggerfish, humuhumunukunukuapua'a, is Hawaii's State fish and is well known for its long name. Hawaii is the only State in the United States with a tropical rain forest. Hawaii is the most isolated population center on the face of the earth. Hawaii is 2,390 miles (3,846 kilometers) from California; 3,850 miles (6,196 kilometers) from Japan; 4,900 miles (7,886 kilometers) from China; and 5,280 miles (8,497 kilometers) from the Philippines. The Waialua River is one of five navigable rivers in Hawaii. It drains off Waialeale Mountain, which averages 488 inches (1,240 centimeters) of rain per year and is considered the wettest spot on earth. Honolulu is the largest city in the world (it has the longest...

The southeastern states contain the rapidly growing urban centers of Atlanta, Greenville, Columbia, Charlotte, and Winston-Salem/Raleigh with suburban corridors between them. In these cities and the surrounding suburbs, large areas of impervious surfaces replace natural streamside habitat, increase pollution and sedimentation, and alter water flow (hydrology). In this 2015 assessment, land cover type was estimated to be a major risk factor for about one-third of the estuaries of the Southeastern states. The United States Department of Agriculture reports that from 1982 to 2012 over 2.6 million acres of rural land in Georgia was developed. Development in North Carolina was almost as high, while South Carolina lost...

Miami, Tampa, Orlando, and Jacksonville rank in the top 50 largest cities in the nation by area. Atlanta and New Orleans are the only other top 50 cities in the Eastern Gulf States region. These four Florida urban centers anchor what is known as the Florida Megaregion, one of eleven recognized in the United States. New Orleans and Baton Rouge are part of the Gulf Coast Megaregion. The growing urban sprawl throughout the Gulf States leads to increasing areas of impervious surface, which results in altered water flows and more urban runoff that transports high levels of nutrients and pollution to aquatic resources. For example in central Mississippi, pathogens, litter/trash, nutrients, and pesticides from increasing...
