The Wild Areas of the Northern Appalachian/Acadian ecoregion are those areas with a Human Footprint score equal to or less that 10 (HF <= 10). These are the 10% wildest, or least human influenced places in the ecoregion. The Human Footprint (HF) of the Northern Appalachian/Acadian ecoregion measures the extent and relative intensity of human influence on terrestrial ecosystems at a resolution of 90 m using best available data sets on human settlement (population density, dwelling density, urban areas), access (roads, rail lines), landscape transformation (landuse/landcover, dams, mines, watersheds), and electrical power infrastructure (utility corridors). The Human Footprint is calculated by assigning Human Influence...

This map service and the attached downloadable layer package represent OpenStreetMap (OSM) road data clipped to the Cascadia Partner Forum geography (with a 10km buffer). The data were obtained from WeoGeo, which converts OSM data from its native format to Esri formats (and others).  They last updated their database on May 1st, 2014. "OpenStreetMap is dedicated to created and providing geographic data, such as street maps, worldwide, for free. Most maps considered "free" actually have legal or technical restrictions on their use. These restrictions hold back anyone from using them in creative, productive or unexpected ways, and make every map a silo of data and effort. OSM's open license gives users the freedom...

The Last of the Wild (LTW) of the Northern Appalachian/Acadian ecoregion are the 120 largest and wildest areas remaining in the ecoregion. The LTW are derived by taking the 10 largest areas in each ecological subregion (12) that have a Human Footprint score equal to or less than 10 (HF <= 10).The Human Footprint (HF) of the Northern Appalachian/Acadian ecoregion measures the extent and relative intensity of human influence on terrestrial ecosystems at a resolution of 90 m using best available data sets on human settlement (population density, dwelling density, urban areas), access (roads, rail lines), landscape transformation (landuse/landcover, dams, mines, watersheds), and electrical power infrastructure (utility...

Human footprint (downloaded from sagemap) was used to determine the amount of human disturbance near pygmy rabbit modeled habitat. Human footprint ranks data on a scale of 1 - 10 (with 1 being the most pristine and 10 being the most anthropogenic). Zonal statistcs was run with the resulting mean score by analysis unit

Humans have dramatically altered wildlands in the western United States over the past 100 years by using these lands and the resources they provide. Anthropogenic changes to the landscape, such as urban expansion, construction of roads, power lines, and other networks and land uses necessary to maintain human populations influence the number and kinds of plants and wildlife that remain. We developed the map of the human footprint for the western United States from an analysis of 14 landscape structure and anthropogenic features: human habitation, interstate highways, federal and state highways, secondary roads, railroads, irrigation canals, power lines, linear feature densities, agricultural land, campgrounds, highway...

The Human Footprint (HF) of the Northern Appalachian/Acadian ecoregion measures the extent and relative intensity of human influence on terrestrial ecosystems at a resolution of 90 m using best available data sets on human settlement (population density, dwelling density, urban areas), access (roads, rail lines), landscape transformation (landuse/landcover, dams, mines, watersheds), and electrical power infrastructure (utility corridors). Each 90m grid cell is attributed with a Human Footprint score between 0 and 100, where 0 represents minimum human influence and 100 represents maximum human influence at that location. The Human Footprint scores (0-100) may be interpreted as the percent influence. The Human Footprint...

The Human Influence Index (HII) of the Northern Appalachian/Acadian ecoregion is a measure of direct human influence on terrestrial ecosystems at a resolution of 90 m using best available data sets on human settlement (population density, dwelling density, urban areas), access (roads, rail lines), landscape transformation (landuse/landcover, dams, mines, watersheds), and electrical power infrastructure (utility corridors). Each 90m grid cell is attributed with a Human Influence Index (HII) score plus the HI score of each input geographic data layer. HII scores are calculated by assigning Human Influence (HI) scores of 0 to 10 to geographic data layers that map features of human activity. Where 0 is no human influence...

This map was developed to map the probablity of cheatgrass in order to examine the overlap of cheatgrass with high priority sagebrush restoration areas. Logistic regression was used to create linear models that were than spatially applied to the landscape. Inputs for regression analysis included elevation, precipitation, soil pH, soil depth, soil salinity, and available water capacity extracted at 6,736 field sampling locations where cheatgrass occurrence was determined.

This map was developed to show the distribution of human influence in the western United States. This dataset was developed from the Human Footprint in the western United States (Leu et al. 2008) in order to ease the interpretation of human footprint comparisons.

Researchers applied methods developed to map cumulative impacts globally to the California Current using more comprehensive and higher-quality data for 25 human activities and 19 marine ecosystems. They first surveyed experts in six sub-regions of the California Current to explore geographic variation in the effects of threats. A workshop was held to use decision theory to evaluate the tradeoffs of using expert opinion to assess threats and associated impacts. Data on ecosystems and threats were gathered at resolutions of approximately one square kilometer. By synthesizing information and inferences regarding anticipated impacts of threats, project participants developed a spatially-explicit understanding of the...

Human footprint (downloaded from sagemap) was used to determine the amount of human disturbance within 2km of Columbia spotted frog modeled habitat.

nthropogenic features such as urbanization, roads, and power lines, are increasing in western United States landscapes in response to rapidly growing human populations. However, their spatial effects have not been evaluated. Our goal was to model the human footprint across the western United States. We first delineated the actual area occupied by anthropogenic features, the physical effect area. Next, we developed the human footprint model based on the ecological effect area, the zone influenced by features beyond their physical presence, by combining seven input models: three models quantified top-down anthropogenic influences of synanthropic predators (avian predators, domestic dog and cat presence risk), and...
