The Jago, Okpilak, and Hulahula rivers in the Arctic are heavily glaciated waterways that are important for fish and wildlife as well as human activities including the provision of food, recreation, and, potentially, resource extraction on the coastal plain. If current glacial melting trends continue, most of the ice in these rivers will disappear in the next 50-100 years. Because of their importance to human and natural communities, it is critical to understand how these rivers and their surrounding environments will be affected by climate change and glacier loss. The overarching goal of this project was to research (1) the amount of river water, sediment, nutrients, and organic matter in the Jago, Okpilak, and...

The Alaska Swan Survey Protocol was first produced by MBM-AK sometime in the 1980s to describe a standardized method of conducting aerial swan surveys in Alaska. It was last updated in 2007. The protocol was not exclusive to the statewide Alaska Trumpeter Swan Surveys described in these metadata; however, it did generally describe these surveys’ flying technique and data collection methods.

The Alaska Trumpeter Swan Survey was an aerial survey conducted by the U.S. Fish and Wildlife Service, Division of Migratory Bird Management, Alaska Region (MBM-AK) and partners to monitor the status of trumpeter swans (Cygnus buccinator) in Alaska. It was first conducted in 1968 and then repeated at five-year intervals from 1975 through 2015. The objectives of the survey were to estimate the abundance, distribution (1968–2005 only), and productivity of trumpeter swans in late summer, when the swans were dispersed on breeding territories and cygnets were large enough to be easily counted from the air. Estimates were obtained for the abundance of white swans (swans >1 year old), cygnets, and total swans, as well...

To better inform conservation efforts targeted at reversing grassland bird declines and ensure self-sustaining populations of at-risk species such as the lesser prairie-chicken (Tympanuchus pallidicinctus), a better understanding of broad-scale habitat availability for grassland birds is needed. his project will evaluate the utility of NDVI and phenology-based metrics in estimating lesser prairie-chicken reproductive habitat quality remotely over broad spatial scales.1. Evaluate the influence of grazing, fire, and precipitation on NDVI-related metrics in the Central and Southern Great Plains.2. Identify NDVI-related metrics that best distinguish lesser prairie-chicken reproductive habitat from non-habitat. 3. Relate...

Population fragmentation compromises population viability, reduces a species ability to respond toclimate change, and ultimately may reduce biodiversi ty. We studied the current state and potential causes offragmentation in grizzly bears over approximat ely 1,000,000 km of western Canada, the northern United States(US), and southeast Alaska. We compiled much of our data from projects undertaken with a variety of researchobjectives including population estimation and trend, landscape fragmentation, habitat selection, vital rates, andresponse to human development. Our prim ary analytical techniques stemmed from genetic analysis of 3,134 bears,supplemented with radiotelemetry data from 792 bears. We used 15 locus microsatellite...

a. Develop a regional map showing the highest probability pathways of wildfire spread under current conditions.b. Design regional networks of fuel breaks to reduce future wildfire size in large remnant tracts of priority GSG habitat. Networks will be designed by modeling fire spread with fuel breaks using Circuitscape (http://www.Circuitscape.org/), a wildlife connectivity software based on electrical circuit theory applied to a raster map, and consulting with agencies and tribes about regional priority habitats in southern ID and OR, northern NV,and northwestern UT.c. Deliver GIS layers and maps showing suggested networks of fuel breaks to federal and state agencies, and tribes. This will allow fire managers to...

Color-infrared imagery collected during spring waterfowl migration for the Rainwater Basin Wetland Complex for 2014.
The Nebraska Game and Parks Commission (NGPC) contracted the Rainwater Basin Joint Venture (RWBJV) to conduct a black-tail prairie dog colony inventory of Nebraska using 1-meter National Agriculture Imagery Program ( 2010) aerial imagery. We estimated the extent of each colony by placing polygon vertices on the furthest visible burrows. Burrows were then re-evaluated using sub-meter resolution imagery. Burrow delineations within 3 kilometers of one another were combined and considered a single colony resulting in 669 distinct colonies totaling 97,438 acres across the state of Nebraska.

Contemporary observations suggest that water may disappear entirely from portions of some North Slope stream-beds during periods of drought or low flow. Climate models project even drier summers in the future. This could pose a problem for migrating fish that must be able to move back and forth from breeding and summer feeding areas to scarce overwintering sites. This work uses the best available long-term hydrologic data set for the North Slope (in the upper Kuparuk River watershed) to develop a model to assess the vulnerability of stream systems to periodic drought, and the vulnerability of migrating fish to a loss of stream connectivity.

The Anaktuvuk River Fire was the largest, highest-severity wildfire recorded on Alaska’s North Slope since records began in 1956. The 2007 Anaktuvuk River Fire was an order of magnitude larger than the average fire size in the historic record for northern Alaska and indices of severity were substantially higher than for other recorded tundra burns. An interdisciplinary team assessed fire effects including burn severity, potential plant community shifts, and effects on permafrost and active layers. Observers monumented, photographed, and measured 24 burned and 17 unburned reference transects, starting the year after the fire, and spanning the range of vegetation types and burn severities.

Arctic grayling (Thymallus arcticus) have a life-history strategy specifically adapted to the extreme climate of the North. These fish migrate to spawning grounds just after breakup in the spring, then migrate to feeding sites in early summer, and finally in the fall migrate back to their overwintering sites. The Kuparuk River is a perennial stream originating in the northern foothills of the Brooks Range on the North Slope of Alaska. Sections of the Kuparuk are periodically intermittent in that, during low flows in the system, these channel reaches appear dry. The flow varies between surface and subsurface in this permafrost-dominated environment, with subsurface flow being limited to the unfrozen thaw bulb around...

The Arctic Tern completes annual epic migrations from pole to pole covering at least 40,000 kmon their round-trip journeys. They breed throughout Arctic Alaska from boreal to tundra habitatsand have their highest nesting densities inland (Lensink 1984). Arctic Terns typically choose nestsites on open ground near water and often on small islands in ponds and lakes (Hatch 2002).Arctic terns consume a wide variety of fish and invertebrate prey, fish are particularly importantduring the breeding season for feeding young (Hatch 2002). This species spends their winters(austral summers) in offshore waters near Antarctica (Hatch 2002). Alaskan Arctic Coastal Plainpopulation estimates from 2011 range from 7-12,000 (Larned...
