Karst aquifers—formed when the movement of water dissolves bedrock—are critical groundwater resources in North America. Water moving through these aquifers carves out magnificent caves, sinkholes, and other formations. These formations are home to high concentrations of rare and endangered species, but the hydrological conditions that support these species can change rapidly. Managing...

Assessing the impact of flow alteration on aquatic ecosystems has been identified as a critical area of research nationally and in the Southeast U.S. This project aimed to address the Ecohydrology Priority Science Need of the SE CSC FY2012 Annual Science Work Plan by developing an inventory and evaluation of current efforts and knowledge gaps in hydrological modeling for flow-­‐ecology...

The Gulf of Alaska is one of the most productive marine ecosystems on Earth, supporting salmon fisheries that alone provide nearly $1 billion per year in economic benefits to Southeast Alaska. Glaciers are central to many of the area’s natural processes and economic activities, but the rates of glacier loss in Alaska are among the highest on Earth, with a 26-36 percent reduction in total...

Biodiversity is declining worldwide, and this trend could potentially become more severe as climate conditions change. An integral component of proactive adaptive management planning requires forecasts of how changes in climate will affect individual species. This need has been identified my multiple federal agencies, including the U.S. Fish and Wildlife Service, National Park Service...

Changing climate conditions have been identified as a major threat to the sustainability and availability of water resources in the Southwestern U.S. Long-term decreases in precipitation can lead to reductions in regional groundwater levels and loss of groundwater storage in aquifers for some communities. Reduced precipitation can also lead to lower water levels in streams and losses in...

Managers already face uncertainty when making decisions about how to best manage natural resources. Now, climate change is adding an additional level of complexity to resource management decisions. Understanding the ability of human and ecological communities to adapt to changing conditions (known as their adaptive capacity) is an integral component of effective management planning in...

Climate affects both the demographics of the Greater sage-grouse bird and the condition and long-term viability of their habitats, including sage-steppe communities. This project builds on collaboration among federal land managers, state wildlife biologists, scientists, and other organizations to create a long-term framework for implementing adaptive management for the sage-grouse. The...

Tribal communities are especially vulnerable to the effects of climate change because of their reliance on the natural environment to sustain traditional activities and their limited resources to respond to climate change impacts. At the same time, tribes have valuable traditional knowledge that can aid regional efforts to address climate change. There were two overarching goals of this...

Caribou populations in Alaska are important to both resident and visiting hunters and provide a large source of income for commercial operators and local communities who provide services to these hunters. Caribou have also provided a traditional staple food source for native Alaskan communities. Moreover, caribou are important prey for wolves and bears and their health and population...

A number of large-scale mapping projects have been completed in the U.S., and several cover all or some parts of the footprint of the Northeast Climate Science Center (NE CSC). These include maps by the Southeast GAP Analysis (SEGAP) program, the national LANDFIRE program, NatureServe, and The Nature Conservancy. These mapping projects represent a major step forward in describing the...

Spatial data depicting marsh types (e.g. fresh, intermediate, brackish and saline) for the north-central Gulf of America coast are inconsistent across the region, limiting the ability of conservation planners to model the current and future capacity of the coast to sustain priority species. The goal of this study was to (1) update the resolution of coastal Texas vegetation data to match...

Over 50% of commercial and recreationally important fish species depend on coastal wetlands. In the Pacific Northwest, coastal wetlands, where the ocean meets the land, are highly productive areas that support a wealth of wildlife species from salmon to ducks. The tidal marshes, mudflats, and shallow bays of coastal estuaries link marine, freshwater, and terrestrial habitats and provide...
