Indicator type	Indicator	Description
Socioeconomic	Commodity production	Amount of commodity produced by oil and gas activity
	Revenue	Dollar ($) value of commodity production
	Employment	Full-time equivalent annual employment
	Wages	Dollar ($) value of annual wages earned by sector employees
	Royalties	Dollar ($) value of annual resource sector royalties generated
	Regional human population	Full-time resident human population
Land use and ecological	Land use infrastructure	Infrastructure metrics that aid in better understanding surface disturbance and linear density indicators
	Surface disturbance	Total amount of direct human-caused surface disturbance (i.e., direct land use footprint) expressed as percent of study area or ha
	Linear density	Total length of linear features (roads, seismic lines, and trails) within a given area, expressed as km/km²
	Habitat Suitability Index (HSI)	Relative ranking of wildlife habitat quality in the absence of potential human-caused habitat effects. HSI values range from 0 (no habitat value) to 1 (perfect habitat value). Indicator is used for range of natural variability runs. Two wildlife focal species HSI indicators were examined: barren-ground caribou winter HSI, and moose late-fall HSI
	Habitat Effectiveness Index (HEI)	Relative ranking of wildlife habitat quality, with consideration of potential human-caused habitat effects. Like HSI, HEI values range from 0 (no habitat value) to 1 (perfect habitat value). HEI can be compared against HSI to understand potential land use impacts. Two wildlife focal species HEI indicators were examined: barren-ground caribou winter HEI, and moose late-fall HEI
