Monitoring Road Dust Emission and Related Dust Effects and Dust Management in National Parks

Document Type


Publication Date



The high number of existing unpaved roads in the Colorado Plateau, and the ongoing expansion of this road system due to activities such as outdoor recreation, tourism, and energy development, raises critical questions about the emission of fugitive dust from roads as well as potential impacts on roadside vegetation. Dust emitted from roads in and near National Parks may influence local biotic and abiotic processes, and result in unexpected and largely unknown impacts to resource conditions. As these anthropogenic drivers of dust emission continue to intensify across the region, land managers are increasingly seeking ways to quantify and monitor road dust emission and transport, and evaluate ecological impacts caused by fugitive road dust as well as its contribution to overall dust emission at a landscape scale...
