Human Footprint of the Northern Appalachians/Acadian ecoregion

Two Countries, One Forest (2C1Forest)


Abstract

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.

A northern spring: hope for the birds, and for me

You hear them long before you see them: a raspy, gurgling call builds on the horizon. Sandhill cranes.

At-risk aquatic acrobat brings national recognition to small northern stream

Two Tree River, a small waterway on St. Joseph Island in the Lake Huron watershed near Sault Ste. Marie, has been identified as a Key Biodiversity Area (KBA), thanks to the presence of a unique aquatic acrobat.
