About

Human Footprint of the Northern Appalachian/Acadian Ecoregion

by Wildlife Conservation Society Canada.


A quantitative evaluation of the continuum of relative human influence on the lands surface


The maps and data sets in this gallery are the result of the Northern Appalachian/Acadian Ecoregion Human Footprint Project. This project was designed to create a down scaled (90m) version of the Global Human Footprint mapped at a scale of 1km by Sanderson et al (2002) 

This Human Footprint (HF)  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 is 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 (no conversion from natural state) and 10 is maximum human influence (complete conversion e.g. urban areas, road surfaces). HI scores assigned to data layers are combined together to calculate the Human Influence Index (HII), that measures total direct human impact.The Human Footprint is a relative measure of human impact - relative to the ecological context. The Human Footprint is calculated by normalizing the Human Influence Index (HII) within ecological subunits within the study area.

The outputs from this project include:

  • The Human Footprint - measure of human impact relative to ecological subregion
  • The Human Influence Index - direct measure of human impact
  • The Last of the WiId - the largest wild areas  ( HF score < 10) within each ecological subregion
