Species-level Effects of Human Footprint
This dataset includes estimates of the effects of human footprint on species at two scales: local scale and region scale. Local scale effects are estimates of the species' predicted relative abundance inside areas that have been disturbed by each sector. Regional population effects are estimates of the total predicted changes in species' populations across the entire region (forested region and prairie region) due to each sector's footprint.
Human Activities Alter Native Habitats
Human activities alter native habitat. The impact of that activity on a species is determined by three factors:
1) how much area the footprint occupies;
2) how strongly—positively or negatively—the species responds to a footprint; and
3) how much of the footprint is in higher- versus lower-quality habitat for the species.
For example, a species that lives in old upland forest may be more affected by the forestry sector than the energy sector, because forestry focuses on those older merchantable stands.
