Ecoregions of Alaska - Level III

This map of ecoregions has been produced for Alaska as a framework for organizing and interpreting environmental data for State, national, and international level inventory, monitoring, and research efforts. The map and descriptions for 20 ecological regions were derived by synthesizing information on the geographic distribution of environmental factors such as climate, physiography, geology, permafrost, soils, and vegetation. A qualitative assessment was used to interpret the distributional patterns and relative importance of these factors from place to place (Gallant and others, 1995).

Level III and IV Ecoregions of the Continental United States

Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas.

Northwestern Interior Landscape Conservation Cooperative

Conservation needs in Alaska and across the nation require an unprecedented
collaborative effort that links science and conservation with the combined
capacities of many conservation partners. Landscape Conservation
Cooperatives (LCCs) are self-directed partnerships that provide science
support for conservation actions that address landscape-level challenges or
stressors such as climate change. The Northwestern Interior Forest LCC is
one of 21 LCCs identified nationally to complete a network approach of

Aleutian Bering Sea Landscape Conservation Cooperative

The Aleutian and Bering Sea Islands Landscape Conservation Cooperative (ABSI -LCC) is one of 21 Landscape Conservation Cooperatives (LCCs) identified nationally to complete a network of LCCs across the nation. The LCC concept was formed as land and resource managers recognized that dealing with the potential effects from climate change will require a stronger level of collaboration. They are designed to provide connections between researchers and managers seeking to address large landscape and seascape concerns.

Arctic Landscape Conservation Cooperative (ALCC)

The Arctic Landscape Conservation Cooperative (ALCC) supports conservation in the arctic by providing applied science and tools to land managers and policy makers. It is a self-directed partnership that functions through a structure of at-large partners, a core staff, and a steering committee of cooperating agencies and organizations. Its geographic scope ranges across North America from Alaska to Labrador. The Alaska portion encompasses three eco-regions: the Brooks Range, the Arctic Foothills, and the Arctic Coastal Plain.

Atlantic and Great Lakes Sea Duck Migration Study

This study is a large scale, multi-year, collaborative project that will use satellite telemetry to document annual migration patterns and habitat use. Driven by a lack of knowledge on sea duck distribution, migration patterns, and seasonal habitats used, the Sea Duck Joint Venture (SDJV) partnership has launched a large-scale satellite telemetry study of sea ducks in the Atlantic Flyway. From 2009 to 2013, about 300 transmitters will be deployed in four species: Black Scoter, Surf Scoter, White-winged Scoter, and Long-tailed Duck - all species of high conservation concern.

Techniques for Determining the Availability of Food Items to Seaducks Wintering on the Chesapeake Bay, Maryland

Introduction: Historically, the Chesapeake Bay has been a major wintering area for seaducks. Based on aerial surveys, three species of seaducks, surf scoters (Melanitta perspicillata), black scoters (Melanitta nigra), and long-tailed ducks (Clangula hyemalis), have shown major declines in recent years. One possible explanation for this decline is a reduction of available food items.Data indicates that surf and black scoters likely feed at depths ranging from 10 to 30 feet in the mesohaline region of the Chesapeake Bay.
