The Yukon-Kuskokwim Delta of Alaska is a globally important region for numerousavian species including millions of migrating and nesting waterbirds. Climate change effectssuch as sea level rise and increased storm frequency and intensity have the potential to impactwaterbird populations and breeding habitat. In order to determine the potential impacts of theseclimate-mediated changes, we investigated both short-term and long-term impacts of stormsurges to geese and eider species that commonly breed on the Yukon-Kuskokwim Delta. Todetermine short-term impacts, we compared nest densities of geese and eiders in relation to themagnitude of storms that occurred in the prior fall from 2000–2013. Additionally, we modeledgeese...

This project evaluated the potential impacts of storm surges and relative sea level rise on nesting geese and eider species that commonly breed on the Yukon-Kuskokwim Delta (Y-K Delta). Habitat suitability maps for breeding waterbirds were developed to identify current waterbird breeding habitat and distributions. Short-term climate change impacts were assessed by comparing nest densities in relation to magnitude of storms that occurred in the prior fall from 2000-2013. Additionally, nest densities were modeled using random forests in relation to the time-integrated flood index (e.g., a storm specific measure accounting for both water depth and duration of flooding) for four modeled storms (2005, 2006, 2009, and...

This project established a permafrost monitoring network in this region, providing a baseline of permafrost thermal regimes for assessing future change at a total of 26 automated monitoring stations. Stations have collected year-round temperature data from the active layer and the permafrost starting from the summer of 2011. The strong correspondence between spatial variability in permafrost thermal regime and an existing ecotype map allowed for the development of a map of ‘permafrost thermal classes’ for the broader study region. Further, the annual temperature data was used to calibrate models of soil thermal regimes as a function of climate, providing estimates of both historic and future permafrost thermal regimes...

Presented by Don Spalinger & Nathan WolfThis seminar focuses on our concepts of regulation of nutrient flows through tundra ecosystems and the effect that climate (or weather) has on these processes. Nutrient flow and climate, in turn, should regulate plant phenology and production, and thus caribou behavior and nutrition. We will present some ideas for assessing the landscape patterns of these processes and monitoring their impacts. Finally, we will provide examples of such assessment and monitoring processes from our work in Western Alaska over the past two years.

This project used existing ShoreZone coastal imagery to map 719 km of shoreline in Bristol Bay, from Cape Constantine to Cape Newenham. This section of coastline is an extremely important herring spawning area and an important component of the Bristol Bay fisheries. Intertidal and nearshore vegetation, on which herring spawn, was catalogued as part of the mapping and, along with shore types, coastal substrate, and coastal biota, added to the state-wide ShoreZone dataset.

The tundra biome is the dominant terrestrial ecosystem of the circumpolar north, and its fate in a rapidly changing climate is of high scientific and socioeconomic concern. One of those concerns is that the majority of caribou herds throughout the circumpolar north are declining, perhaps as a result of climate change. The principal objective of this research is to reveal the connections between soil nutrient cycling, forage quality and caribou habitat selection. This framework is underpinned by the concept that tundra ecosystem productivity is ultimately driven by the thermodynamics of the system induced by climate.

The Yukon–Kuskokwim Delta of Alaska,USAis a globally important region for numerous avianspecies including millions of migrating and nesting waterbirds.However, data on the current spatial distributionof critical nesting areas and the importance of environmental variables in the selection of nest locations aregenerally lacking for waterbirds in this region.We modeled nest densities for 6 species of geese and eiders thatcommonly breed on the Yukon–Kuskokwim Delta, including cackling goose (Branta hutchinsii minima),emperor goose (Chen canagica), black brant (B. bernicla nigricans), greater white-fronted goose (Anser albifronsfrontalis), spectacled eider (Somateria fischeri), and common eider (S. mollissima).Thedata...

The Yukon-Kuskokwim Delta of Alaska is a globally important region for numerous avian species including millions of migrating and nesting waterbirds. Climate change effects such as sea level rise and increased storm frequency and intensity have the potential to impact waterbird populations and breeding habitat in the near future. In order to determine the potential impacts of these climate-mediated changes, it is important to monitor the current spatial distribution of important nesting areas and understand the importance of environmental variables in the selection of nest locations. To do this, we modeled nest density for 15 species or composite species of waterbirds that commonly breed on the Yukon-Kuskokwim Delta,...

The Western Alaska LCC was one of the second tier LCCs to get established (officially started in 2011). With funding from FWS, Western AK LCC staff were hired in 2010 and they held a series of nine (9) meetings in October and November 2010 throughout the western Alaska region to speak with potential partners and solicit input on early directions for the LCC. Meetings were held in Cold Bay, King Salmon, Dillingham, Anchorage, Kodiak, Bethel, Fairbanks, Kotzebue, and Nome. Over 100 people participated in the series of local meetings, including representatives of federal and state agency staff, non-‐profit organizations, Alaska Native Tribes and organizations, academia, and local residents. The Arctic Research Consortium...

Webinar 2015: Alaska’s National Hydrography Dataset (NHD), the digital data layer that depicts the location of lakes and streams, was originally created from the 1950’s topographic maps. With funding support from the LCC Network, this project focused on establishing a statewide framework to improve the hydrography mapping and stewardship in Alaska. This will be achieved through the creation of a statewide system to make digital mapping data updates accessible and affordable, and through the creation of a statewide hydrography mapping coordinator position to synchronize updates and guide hydrography mapping development. This framework will allow agencies and organizations to greatly improve their hydrography mapping...
The Western Alaska LCC, the Department of Interior’s Alaska Climate Science Center and the Bureau of Land Management brought together 150 land and resource managers, field specialists, researchers and local knowledge experts to identify climate change related priority science/information needs for land and resource management in western Alaska. The workshop results help inform development of the LCC’s Science Strategy, which will guide the LCC’s efforts over the next ten years. The workshop was modeled in part after the 2007 WildREACH Workshop for the arctic region. Attendance was by invitation; workshop organizers sought diverse cross-program and cross-agency participation.

Map showing the area proposed for ShoreZone mapping (in red) with FY13 funds from the Western Alaska Landscape Conservation Cooperative funds; the coastline with existing ShoreZone imagery and mapped data in blue; and the coastline with existing ShoreZone imagery that remains to be mapped in green. This imagery was collected in either 2006 (Bristol Bay survey July 19-23, 2006) or 2011 (Southwest Alaska/Alaska Peninsula May 16-21, 2011).This project provided systematic coastal habitat imagery and mapping for the Alaska Peninsula shoreline following the Alaska ShoreZone Mapping Protocol and made these products web-accessible. The completed mapping product is available on the ShoreZone website in a searchable dataset....
