Between September and November each year, nearly the entire world population of Pacific black brant (Branta bernicla nigricans) stages at Izembek Lagoon and surrounding estuaries (hereafter: Izembek Complex). The Izembek Complex is a unique area of protected brackish waters, supporting one of the world’s largest eelgrass beds and a diverse array of wildlife. The Alaska Fall Brant Survey has been conducted annually since 1976 in late-September through October, to provide an index of abundance for the entire post-breeding Pacific black brant population (Branta bernicla nigricans), while secondarily, providing annual fall population indices for cackling geese (Branta hutchinsii), emperor geese (Anser canagicus), and...

Cropland conversion is a leading cause of human modification that threatens the ecological function of the sagebrush (Artemisia spp.) biome – the most intact biome remaining in the conterminous United States. However, despite its prevalence relatively little is known about the extent and risk of cropland conversion as well as the landscape scale benefits of easements in combating cropland conversion. Therefore, our goals were to: 1) quantify the cropland area of the sagebrush biome, 2) identify where the highest quality sagebrush rangelands are most at risk to future cropland, and 3) estimate the ecological benefits of conservation easements to adjacent public lands. Our findings show that croplands span over 14.4...

Boreal wetland birds are among the continent’s most rapidly declining avifauna. However, many of these declining species still breed commonly on military lands in Alaska. We propose to survey these species, as well as, additional boreal wetland obligates at breeding sites on Eielson Air Force Base (AFB) and then track migratory movements throughout the annual cycle. Our surveys aim to identify important wetland features for conservation and levels of fragmentation that may reduce bird breeding numbers. Our tracking of birds during migration will identify habitats for conservation at key stopover and wintering areas, and therefore allow conservation on military lands in Alaska to be directly linked to conservation...

The Pacific Flyway Winter Brant Survey (WBS) has been conducted annually since 1981 as part of a cooperative effort by the U.S. Fish and Wildlife Service, Canadian Wildlife Service, Mexico, and the Pacific U.S. states, to estimate the abundance of the Pacific black brant (Branta bernicla nigricans) in their principal wintering areas along the Pacific Coast (in Baja, Mexico, California, Oregon, Washington, British Columbia, and Alaska). The survey is conducted each winter in January-February by a composite of ground and aerial crews, with the Alaska portion being conducted by the Alaska Region of USFWS Migratory Bird Management. The primary objective of the Alaska survey component is to provide an annual index of...

Many of North America’s most rapidly declining avifauna breed in the boreal and alpine ecosystems of Alaska. Joint Base Elmendorf-Richardson (JBER) located in Anchorage, Alaska, provides critical nesting habitat for five avian Species of Special Concern (SOSC): Solitary Sandpiper Tringa solitaria, Lesser Yellowlegs Tringa flavipes, Olive-sided Flycatcher Contopus cooperi, Rusty Blackbird Euphagus carolinus and Blackpoll Warbler Setophaga striata. Joint Base Elmendorf-Richardson derived the Species of Special Concern list from the Birds of Conservation Concern (USFWS 2008) and the Department of Defense Mission-Sensitive Priority Bird Species (DoD PIF 2015) lists. Department of Defense Partners in Flight recognizes...

The roselaari subspecies of Red Knot is one of the rarest shorebird populations breeding in North America, based on a the current population size estimate of 17,000 individuals (Carmona et al 2013). As a result of suspected declines,the roselaari subspecies has been designated as threatened by the Committee on the Status of Endangered Wildlife in Canada and was petitioned for listing under the U.S. Endangered Species Act. The U.S. Fish and Wildlife Service’s decision to not conduct a full status review for listing was based on the lack of substantial information identifying threats and population trends (USFWS 2011). The apparent low population size coupled with the scarcity of information on many demographic and...
