These varying alignments are a result of the use of differing source data sets and all products derived from them. We recommend that users snap or align rasters as best suits their own projects. - This file includes a downscaled projection of decadal average of spring (March, April, May) total precipitation (in millimeters) for the decades 2010-2019, 2020-2029, and 2060-2069 at 771x771 meter spatial resolution.

Alaska's abundant, remote, and predominantly pristine freshwater fish habitats are largely unexplored and undocumented. To begin filling these vast information gaps, the Alaska Freshwater Fish Inventory Database (AFFID) houses freshwater fish (anadromous and resident)-occurrence data sets compiled from a variety of sources. Most records in the AFFID come from Alaska Department of Fish and Game (ADFG) fish and aquatic habitat inventories. However, the AFFID also includes selected recent fish-occurrence data sets from ADFG Fish Resource Permit fish-collection reports submitted to ADFG by other organizations (agencies, consulting firms, non-governmental organizations, and individuals) who collect fish for scientific...

Fish occurrence data have been collected within the North Slope study area, however most of these data are presently available only in non-digitized format (e.g., hardcopies, inventory reports, unpublished data, etc.). Due to the lack of spatial data available, Alaska Natural Heritage Program began collaboration with BLM fisheries biologists to assist with their efforts to enter these fish distribution datasets into the geodatabase RipFish that was developed and is maintained by BLM. Our contribution to this database serves as a final product for the Aquatic Fine-Filter CEs for the Rapid Ecoregional Assessment and will allow managers to readily have access to fish distribution data and conduct future spatial analyses....

Each community in the study area is served by an isolated grid, with its own generation and distribution infrastructure. All energy infrastructure in each community is within the community’s footprint. Barrow and Prudhoe Bay, the two largest population centers, rely completely on natural gas for generation of electricity. Nuiqsut relies both on natural gas and diesel. Other than Barrow and Prudhoe Bay, all other communities have small demand loads, and thus only generate less than a megawatt.

The majority of the transportation infrastructure is related to oil industry activities. Other community transportation infrastructure – existing and planned – is small in comparison to the oil industry’s activities, as well as small in comparison to other U.S. communities. The transportation network in the region includes airstrips, few paved or gravel roads within communities, and a network of trails to subsistence use areas and those that connect communities. Most communities in the region are located along the northern coast of Alaska, with Nuiqsut, Prudhoe Bay, Atquasuk, and Noatak located along rivers. Travel to and from communities in the region is largely limited to air travel. While many rivers in the region...

Willow ptarmigan (Lagopus lagopus) occupy the boreal and arctic northern hemisphere, and are one of the few bird species that remain in the Arctic year-round. In Alaska and northern Canada, willow ptarmigan are common in areas with patches of dense vegetation, especially where willow (Salix) or birch (Betula) shrubs are abundant. They are also found in sedge-willow (Carex-Salix) marshes, in meadows, along road and forest edges, and on open tundra. Unlike Rock Ptarmigan (L. muta), the species avoids dry, rocky areas. After chicks hatch, birds move to wetter areas, such as marshes and along streams. Willow ptarmigan were selected as a Terrestrial Fine-Filter CE for this assessment because they are an important prey...

Species selected to represent the “Raptor Concentration Areas” assemblage for the North Slope study area include gyrfalcon (Falco rusticolus), peregrine falcon (Falco peregrinus tundrius), and rough-legged hawk (Buteo lagopus). These three species share similar habitats in arctic Alaska, but differ in seasonal distribution and prey preferences. Primary habitats include cliffs in riparian areas along river drainages and major tributaries, shale banks, mud or sand banks, scree and talus slopes, and steep escarpment faces. This species assemblage was nominated as a Terrestrial Fine-Filter CE because of the role raptors play as top trophic-level predators.

Previous to this effort there were no maps available, digital or otherwise, showing the likely present-day distribution...

We recommend that users snap or align rasters as best suits their own projects. - The majority of current raptor concentration distribution locations are in areas with very high (intact) landscape condition. Future projections of landscape condition suggest very little change in landscape condition in the vicinity of riparian corridors and areas occupied by these species. Although landscape condition appears...

However, very low condition is indicated in high density nesting areas around Prudhoe Bay and Nuiqsut. Future scenarios of landscape condition do not indicate any significant changes in both medium and high...
