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 purpose of this project is to provide better information to industry and regulatory agencies regarding the likely locations of polar bear dens. This project integrates snow physics, high-resolution digital elevation data, and bear biology to produce more refined and accurate maps predicting suitable polar bear den habitat than are currently available. The work consists of data gathering, consultation between snow and bear scientists, modeling, and sensitivity studies to understand the various factors influencing den location and evolution along the Beaufort Coast.The proposed work is intended to refine current methods of identifying polar bear denning sites by incorporating higher-resolution topographic data...

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...

Purpose:The purpose of this Walker Basin Meadows Condition Report is twofold. First, it provides condition data and explains why the Walker Working Group chose the first set of meadows as the top priority for restoration. Second, the working group will use information presented here to plan subsequent restoration efforts once the first group of meadows is restored.Introduction:Meadows of the Walker River basin are an extremely valuable component of the landscape. Meadows provide diverse habitat, including habitat critical to endangered species. They reduce peak flows during storms and soak up spring runoff, recharging groundwater supplies. Meadows filter sediment, provide forage, and are important cultural and recreational...

A combination of citizen science inventories and expert assessments will be used to collect critical baseline information on known spring and seep resources using the Spring Ecosystem Inventory and Assessment Protocols and adapting them as needed for the unique arid Sky Island ecosystems. The assessment will collect information on channel morphology, riparian and wetland vegetation, water quality, aquatic macroinvertebrates, and wildlife. This information will be combined with historic data from cooperating agencies (Pima County, Santa Cruz County, USFS, NPA, USGS, USFWS, BLM, and AGFD) in a regional, on-line database to provide a landscape level context for managing resources, which was previously unavailable due...
