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...
The Future Human Footprint (FHF) of the Northern Appalachian/Acadian ecoregion projects the extent and relative intensity of human influence on terrestrial ecosystems over a 20-40 year span 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 Future Human Footprint uses as a basis the Current Human Footprint, and projects forward salient, dynamic features of human infrastructure including residential roads, human settlement, and amenity development. It attempts to capture two dominant...
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...

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 difference maps of the Future Human Footprint (FHF) and Current Human Footprint (CHF) of the Northern Appalachian/Acadian ecoregion portray the differences that may accumulate over time under each scenario. Please see metadata for the CHF and each FHF in order to understand how those layers are made. This difference map portrays the potential change over time - relative to the CHF - modeled by the "Current Trends" Future Human Footprint.The map is created by subtracting the current human footprint from the scenario modeled Future 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...
The City of Kentwood (MI) has been faced with repetitive flooding from Plaster Creek near the intersection of Shaffer Avenue SE and 36th Street SE. Nearby businesses and public and private property are at risk for flood damage; as well as degradation of public infrastructure including bridges, exposure of subsurface sanitary sewer lines, and damage to storm water systems. The U.S. Army Corps of Engineers, Detroit District, would like to develop a management plan through the use of a hydraulic model of the impacted river reaches. To support this effort, topographic and bathymetric surveys of Plaster Creek, Little Plaster Creek, and associated bridges and structures are needed. During the summer of 2018, the U.S....

The Last of the Wild Dataset of the Last of the Wild Project, Version 2, 2005 (LWP-2) is derived from the LWP-2 Human Footprint Dataset. The gridded data are classified according to their raster value (wild = 0-10; not wild >10). The ten largest polygons of more than 5 square kilometers within each biome by realm are selected and identified. The dataset is produced by the Wildlife Conservation Society (WCS) and the Columbia University Center for International Earth Science Information Network (CIESIN) and is available in the Geographic Coordinate system.

Human intervention in the hydrologic basin of the Colorado River has eliminated water discharge and sediment supply to the river's mouth and its delta. After not, vert, similar95 years of applying strong flow control policies, the previous sedimentary budget in the delta has changed, the delta now being entirely exposed to the hydrodynamic forces in its basin. In order to assess the anthropogenic impact of water diversion on deltaic sedimentary processes and short-term delta geomorphic evolution, textural and mineralogical analyses were performed on 68 sediment samples collected from the river, estuary, beach, continental shelf, delta plain and desert. The results show a consistent NE to SW textural gradient on...

The City of Kentwood (MI) has been faced with repetitive flooding from Plaster Creek near the intersection of Shaffer Avenue SE and 36th Street SE. Nearby businesses and public and private property are at risk for flood damage; as well as degradation of public infrastructure including bridges, exposure of subsurface sanitary sewer lines, and damage to storm water systems. The U.S. Army Corps of Engineers, Detroit District, would like to develop a management plan through the use of a hydraulic model of the impacted river reaches. To support this effort, photographs of debris jams within Plaster Creek, Little Plaster Creek were collected during the summer of 2018. A companion shapefile is provided to show the approximate...
Environments dominated by human disturbance such as roads, cities, and the constructed materials that support human habitation have profound effects on species. For most species, this data layer was used to exclude species from a portion of the landscape. However, some species respond favorably to human habitats, therefore this data layer was used in an inclusionary manner. The human impact avoidance dataset describes high exclusion/high inclusion proximity to urban environments, and roads. This dataset was derived from US Census TIGER/Line files and GAP’s National Land Cover Database developed by USGS, in particular the impervious dataset. These data are divided into 6 regions across the US (Northwest, Southwest,...
Raster data depicting estimated jaguar energy expenditure required to move north from the US-Mexico border to reach important water sources. The data were generated for five scenarios: walled, un-walled crossing and three remediation scenarios: a border crossing through the wall in rugged terrain towards the west end of the wall, a crossing in a dry wash centrally located, one in less rugged terrain east of both.
