PEM_20K contains 1:20,000 PEM polygons with key and amalgamated (concatenated) attributes derived from the Resource Inventory Standards Committee (RISC) standard attributes. PEM divides the landscape into units according to a variety of ecological features including climate, physiography, surficial material, bedrock geology, soils and vegetation. PEM uses a modeling approach to ecosystem mapping, whereby existing knowledge of ecosystem attributes and relationships are used to predict ecosystem representation in the landscape. This layer is derived from the STE_TEI_ATTRIBUTE_POLYS_SP layer by filtering on the PROJECT_TYPE and PROJECT_MAP_SCALE attributes
Terrain Inventory Mapping (TIM) contains polygons with key and amalgamated (concatenated) attributes derived from the RISC (Resource Inventory Standards Committee) standard attributes. TIM is multi-purpose and divides the landscape into unit according to surficial material, surface expression and geomorphological process using the Terrain Classification System for British Columbia. Most of the inventory mapping was completed in the 1970's and 1980's on 1:50 000 scale base maps using air photo interpretation with selective field checking, and manual transfer and drafting of paper maps. These maps were later digitized and have been converted from IGDS or CAPAMP to ArcInfo to Geodatabase. This layer is derived from...
The USGS Western Ecological Research Center (WERC) comprises a dispersed science community collocated with DOI agencies, academic institutions, or proximal to critical ecosystems. WERC scientists conduct peer-reviewed research using innovative tools to provide natural resource managers with the knowledge to address challenges to ecosystem function and service in Pacific West landscapes. Four Scientific Themes define the research of WERC scientists: Species and Landscape Response to Human Activity Renewable energy development, urbanization, water abatement, prescribed fires, barriers to movement, and invasive species are among key factors that impact Pacific western US natural resources. To identify potential impacts...
Fresh water is arguably the most valuable resource on the planet, but human activities threaten freshwater ecosystems. For example, use of synthetic chemicals, such as pesticides, road salts, and nutrients, has led to the ubiquitous contamination of aquatic systems, jeopardizing the integrity of ecological communities. Given the importance biodiversity plays in maintaining ecosystem health and function and the continued decline of freshwater species, it is vital to understand the direct, indirect, and lasting effects of synthetic contaminants on biota in freshwater systems. The majority of our knowledge regarding contaminant effects is comprised of short-term, single-contaminant laboratory toxicity tests that describe...
This collection contains the report log files produced by the R Package “AKaerial” when the QC data were created from the raw transcribed data. The QC log files document the quality control process, data standards, and what changes (if any) were made to the QC data compared to the raw data. Each log file was named following the same file naming conventions: SSSYYYY_QCLog_OOOO, where; YKD=Duck data, YKG=Goose data, YYY=Year, and OOO=observer’s first initial and last name.

R code that takes in the nest capture history data (chdata.csv), reformats it for model fitting in the Bayesian MCMC software JAGS via the R package jagsUI. Various generalized linear mixed models are fit using a Huggins two occasion capture history model structure as in Program Mark. A series of models of increasing complexity are fit and compared using DIC. Model text is written to text files for each model but is generally not used or saved. Posteriors are saved as Rworkspaces or written to text files for use in population estimation (nostpop.R). Code can be run to generate model results and R workspaces/objects to inspect parameter estimates. The primary purpose of this code is to compare various mixed model...

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 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...

DATA ANALYSIS AND VISUALIZATION,
This map depicts the distribution of sagebrush and associated shrub-steppe habitat types using readily available data from a variety of source maps from WA, OR, CA, UT, NV, CO, WY, MT, ND, SD, AZ, NM, AB, and BC. Habitat was grouped from map sources that were classified with detailed information on specific sagebrush types, as well as coarse-scale maps that classified vegetation as only "shrub" in the case of ND and the Canadian provinces. This map is a 90-meter grid, but source material included 30 to 90-meter grids, and 1:24,000 and 1:100,000 polygon coverages.
This map was developed to examine multi-scale spatial relationships between percentage of sagebrush and other response variables of interest. A map of sagebrush in the western United States was used as a base layer for a moving window analysis to calculate the percentage of the area classified as sagebrush within the given search radius.

The Northern Colorado Plateau Network (NCPN) is one of 32 National Park Service (NPS) inventory and monitoring networks nationwide that are implementing vital signs monitoring in order to assess the condition of park ecosystems and develop a stronger scientific basis for stewardship and management of natural resources across the National Park System. The network approach facilitates collaboration and information sharing, and will provide parks with a minimum infrastructure for initiating natural resource monitoring that can be built upon in the future. The NCPN consists of 16 parks with diverse cultural and natural resources distributed across four states and three physiographic regions. Ecosystems include desert...
The article argues that the currently dominant idea of material welfare is at odds with a lifestyle that does justice to basic human values. Measurement of welfare needs to attach importance to a good environment. With regard to the subjective counterpart: social research on the experience of welfare - the quality of life - in various Western countries shows clearly that intangible values are very important in the lives of most people. In a process of globalization of economy and cultural supplies, it will be important to strengthen democratic concern with the environmental question. The legitimation of political authority in (inter)national negotiations will depend on the attention paid to welfare and quality of...

The purpose of this Assessment is to understand how much upland hardwood forest and woodland habitat is available and what condition that habitat is currently in relative to habitat targets, or endpoints, defined in the ISA. To assess the ISA endpoints for upland hardwood systems, it was necessary that the most consistent, comprehensive, current and accurate data be used in summary and analysis. For the best possible assessment product we cross-checked geospatial datasets spanning variable time periods and data sources in the Ozark Highlands subgeography and remainder of the GCPO geography.
