Statewide lakes were assembled from seventeen separate files in the USGS 1:2,000,000 Digital Line Graphs (DLG) dataset and include only those polygons with AREA greater than 20 acres (80940 square meters). Polygons with the attribute MIN = 100 or arcs with the attribute LINECODE = 'L' are valid lakes. For data codes and details, please refer to the US Geological Survey Circular 895, 1982. Due to the limitation of ARC/INFO software at the time of processing these files, the lakes were originally processed into three groups. Then a framework of arcs surrounding those three groups allowed all the lakes to be united into one statewide lakes coverage. Any lakes which were interested either by the boundaries of the seventeen...

Some of the YKL rasters intentionally do not align or have the same extent. These rasters were not snapped to a common raster per the authors' discretion. Please review selected rasters prior to use. 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 mean Day of Thaw (in ordinal dates) for the decade 2060-2069 at 771x771 meter spatial resolution. Day of Thaw approximates when the running mean rises above 0°C. Although raster values represent ordinal dates, the values 0 and 365 are special classes. A value of 0 indicates...

We recommend that users snap or align rasters as best suits their own projects. - The landscape condition model (LCM) evaluates the degree of human impact on the landscape. The current landscape condition was extracted to the current distribution of spruce forest. The intersection of the white spruce or black spruce CE distribution with the LCM suggests that over 94% of the total CE area is very high (intact)...

Chinook salmon (Oncorhynchus tshawytscha) are an anadromous fish species that migrate through, feed in, and spawn in the Yukon River Lowlands - Kuskokwim Mountains - Lime Hills. This dataset provides the current (2013) spatial distribution of chinook salmon within the REA study area for the analysis of chinook salmon as an Aquatic Fine-Filter Conservation Element. This dataset was derived by clipping the chinook salmon distribution from the Anadromous Waters Catalog to the boundaries of the study area for this REA. The Anadromous Waters Catalog is developed and maintained by the Alaska Department of Fish and Game. It includes all waters known to include populations of anadromous fish but does not differentiate by...

"Cliomes" can be considered to be assemblages of species and aggregated communities that might be expected to occur based on linkages with prevailing climate conditions. They are not the same as actual biomes,...

This shapefile includes projections of annual area burned, fire return interval, and percent forest (current decade only) for the current (2010s), near-term (2020s) and long-term (2050s and 2060s) decades, for the A2 emissions scenario, for 3rd level HUCs within the YKL REA study area. Values were obtained by running 100 repetitions of the Alaska Frame-Based Ecosystem Code (ALFRESCO) model for the top five performing global climate models in the Arctic at a 1x1 km resolution. These outputs were then averaged together to determine the composite, 5 model average, the decades of interest extracted, and the resulting table exported as a shapefile. For background on ALFRESCO, please refer to: Is Alaska's Boreal Forest...

This report presents updated information about subsistence uses of fish, wildlife, and plant resources in 5 communities of southcentral Alaska - Igiugig, Kokhanok, Koliganek, Levelock, and New Stuyahok. The Division of Subsistence of the Alaska Department of Fish and Game conducted the study in collaboration with Stephen R. Braund & Associates. Phase I of this study took place in the communities of Iliamna, Newhalen, Nondalton, Pedro Bay, and Port Alsworth in 2005, to document subsistence uses and harvests and demographic and other economic data for the study year of 2004 (Fall et al. 2006). This report documents findings from phase II which expanded the study to 5 additional communities within the watersheds that...

This report presents information about subsistence uses of fish, wildlife, and plant resources in Lime Village, Interior Alaska. This is the first harvest assessment survey for this community since a compilation of qualitative harvest data was completed in 1983. The Alaska Department of Fish and Game Division of Subsistence conducted the project in collaboration with Stephen R. Braund & Associates as part of a multiyear, multiphase study in a region of Southwest Alaska being considered for the development of a large scale mine. The Pebble Project is a mineral deposit in an advanced exploration stage located near Frying Pan Lake, which is 100 miles south of Lime Village. The Pebble Project requires updated baseline...
