The Alaska Center for Conservation Science at the University of Alaska Anchorage, in partnership with the Northwest Boreal LCC and the US Fish and Wildlife Service, embarked on a project to map and quantify the human footprint and fisheries resources across the Yukon River watershed. The maps presented here show the footprint of human activities (ie., mining, transportation), as well as fisheries resources across this watershed.
This is the YKD egg observation data summarized into yearly stats on mean initiation and hatch dates for various species. This file is produced from the R code eggs.R.
This Atlas describes 85 sites throughout North America that constitute important sea duck habitats. It is intended to heighten awareness of valuable sea duck habitats, aid in prioritizing habitat conservation and protection efforts, and help in evaluating environmental assessments. Criteria for inclusion in this atlas were strict, relative to criteria used for other bird habitat designations, to highlight those habitats most critical to sea ducks during at least one season. To be included in this atlas, sites had to meet the following minimum criteria: (1a) The area supports at least 5% of the continental population of a sea duck species, or (1b) The area supports, or has recently supported, a total of 20,000 sea...

This is the quality controlled YKD salinity data for fixed and random plots 2006 - 2019. These data are quality controlled using the R code in the file 'YKDsalinity_QC.R' to produce the data used for analysis and sharing ('YKDsalinity_QC.R'). These data should be what is used for analysis or distributed on request.
In recent decades, Rocky Mountain accumulated snowpack levels have experienced rapid declines, yet long-term records of snowpack prior to the installation of snowpack observation stations in the early and mid 20th century are limited. To date, a small number of tree-ring based reconstructions of April 1 Snow Water Equivalent (SWE) in the northern Rocky Mountains have extended modern records of snowpack variability to ~1200 C.E. Carbonate isotope lake sediment records, provide an opportunity to further extend tree-ring based reconstructions through the Holocene, providing a millennial-scale temporal record that allows for an evaluation of multi-scale drivers of snowpack variability, from internal climate dynamics...
This raster, created in 2010, is output from the Geophysical Institute Permafrost Lab (GIPL) model and represents simulated mean annual ground temperature (MAGT) in Celsius, averaged across a decade, at the base of active layer or at the base of the seasonally frozen soil column. The file name specifies the decade the raster represents. For example, a file named MAGT_1980_1989.tif represents the decade spanning 1980-1989. Cell values represent simulated mean annual ground temperature (degree C) at the base of the active layer (for areas with permafrost) or at the base of the soil column that is seasonally frozen (for areas without permafrost). If the value of the cell is negative,the area has permafrost and the...
The ETPBR LCC Steering Committee (SC) consisted of 20-30 representatives from state, federal, tribal, and NGO entities. In December 2012, the LCC Steering Committee began drafting a strategic plan to provide a foundation and structure to carry out the mission and vision of the LCC and its partners. The SC met twice a year from 2012 to 2016 in various locations around the Midwest. Staff worked with the committee and project investigators to compile information for a set of descriptive flyers, posters, presentations, and annual updates.
This is the YKD nest card data from 1985 to 2019 produced after processing with the R script "Nest_Cards_QC.R". This file ('Nest_Cards_1985_2019_QC.csv') should be used for producing population estimates and any other analyses. This file is what should generally be distributed for YKD nest card data requests.
This is the YKD egg observation data reformatted from the nest card data ('Nest_Cards_1985_2019_QC.csv'). The file eggs.R is used to produce this data set, and then this is further summarized into yearly stats on mean initiation and hatch dates to produce the file yearstats.csv.
This geopackage contains the density strata that were used to create the Alaska Arctic Coastal Plain Aerial Breeding Pair Survey four-year rotating panel design. This file was derived from a mid-1980’s ArcInfo coverage for the North Slope Eider Survey that was produced through the visual interpretation of 1:250,000-scale LANDSAT imagery and the known nesting density waterfowl in the area.

This NetCDF represents the monthly inputs and outputs from a United States Geological Survey water-balance model (McCabe and Wolock, 2011) for the conterminous United States for the period 1895-01-01 to 2020-12-31. The source data used to run the water balance model is based on the National Oceanic and Atmospheric Administration's(Vose and others, 2020) ClimGrid data for precipitation and temperature. This NetCDF contains the following monthly inputs: temperature (degrees Celsius) and precipitation (millimeters, mm) and the following outputs (all in mm): runoff, soil moisture storage, actual evapotranspiration, potential evapotranspiration, snow water equivalent, and snowfall. The spatial reference for this data...
This scenario planning decision support tool for the Kankakee River basin as a first case study/proof-of concept. Hydrology models, both surface water and groundwater, and ecology of the Kankakee River watershed will be combined to evaluate the effects of habitat restoration on water suppy ecosystem services, agricultural irrigation demands, urbanization, and waterfowl habitat, and sportsman and recreational user interests. Various scenarios for restoration identified with peer input were tested for the watershed. Each scenario results in different individual and aggregate values for ground water recharge, surface water storage, waterfowl habitat, sportsman and recreational use, and agricultural capacity. Some...

The Arctic Coastal Plain (ACP) of Alaska is an important region for millions of migrating and nesting shorebirds. However, this region is threatened by climate change and increased human development (e.g., oil and gas production) that have the potential to greatly impact shorebird populations and breeding habitat in the near future. Because historic data on shorebird distributions in the ACP are very coarse and incomplete, we sought to develop detailed, contemporary distribution maps so that the potential impacts of climate-mediated changes and development could be ascertained. To do this, we developed and mapped habitat suitability indices for eight species of shorebirds (Black-bellied Plover [Pluvialis squatarola],...

This collection contains the quality-control (QC) transcribed data from the Arctic Coastal Plain Aerial Breeding Pair Survey. These QC data were produced from the “raw” data using the R Package “AKaerial.” The raw data were evaluated against the current data standards in the ‘AKaerial data dictionary’ and saved to new QC data files with associated log files that document any changes that were made. The data files in this collection were named using the following naming convention: ACP_YYYY_QCObs_OOOO, where ACP=Arctic Coastal Plain, YYYY=Year, QCObs=Quality control observations, and OOOO=observer’s first initial and last name. These data contain known errors. These data should not be used except as raw input for...

This multi-layer GeoPackage contains the Alaska Arctic Coastal Plain Aerial Breeding Pair Survey design transects from 2007 to present. The original transects were created as shapefiles and imported to this SQLite database. Transects were saved as individual polylines named according to the year they were created (e.g., “main.ACP_2007_Trans,” “main.ACP_2008_Trans,” “main.ACP_2009_Trans,” etc.). These aerial transects were developed systematically from randomly-selected start points and created along constant lines of latitude. The inter-transect spacing in the low, medium, high, and very-high density strata varies so that areas with higher waterfowl density are surveyed more intensively. The current four-year rotating...

In the Prairie Pothole Region (PPR) wetland plant, invertebrate, and waterbird productivity are primarily driven by water-level dynamics in response to climate cycles. Large proportions of wetlands in the PPR have been drained, often consolidating water from smaller to larger-interconnected wetlands. This project will examine whether large basins that receive inflow from consolidation drainage have reduced water-level dynamics in response to climate cycles than those in undrained landscapes, resulting in relatively stable wetlands that have lower densities of invertebrate forage for ducks and shorebirds. We will also include a sample of wetland historically used by piping plovers to assess the threat of consolidation...
Annual assessment of nesting populations of geese on the Yukon-Kuskokwim Delta (YKD) provides information for biologists, participants in cooperative goose management plans, and Pacific Flyway technical committees. A ground-based sampling procedure has been used since 1986 to estimate the number of total nests, active nests, and eggs for cackling geese, emperor geese, greater white-fronted geese, and spectacled eiders. Annual information on the size of the nesting population and potential number of young produced contributes long term data needed to understand goose and eider population ecology and better manage these species. The survey has been the primary method of measuring recovery status for the western population...
A data management plan (DMP) helps staff identify and plan to support the data management needs of a project. This document provides guidance on how to develop a DMP and identifies the items that should be considered to help ensure that data and associated products are documented, discoverable, accessible and secure throughout their useful lifespan. A DMP: 1) identifies key data management roles, 2) identifies project staff that will fill those roles and perform the associated duties and 3) summarizes how data are acquired, used, maintained and distributed. Any non-standard workflows, security requirements or access restrictions should be emphasized in the DMP.The information in a DMP is used by project staff to...
