Technical note on a map of human modification in CONUS for 2021

The purpose of this note is to briefly describe a detailed (270 m) spatial dataset that estimates the degree of human modification for the lands of the continental US reflecting ~2021 conditions. The degree of human modification is a well-established method to estimate the proximate human activities or processes that have caused, are causing, or may cause impacts on biodiversity and ecosystems. This includes stressors for: urban and built-up, crop and pasture lands, livestock grazing, oil and gas production, mining and quarrying, power generation (renewable and nonrenewable), roads, railways, power lines and towers, logging and wood harvesting, human intrusions, and air pollution.
