In one report, the USDA highlights several potential problems when it comes to trail building: effects on natural resources, use of designated wilderness, conflict with other users, and notable safety issues. These regulations are devised to make mountain biking sustainable; the IMBA strives to promote mountain biking in a way that trails made are done so according to previously ordained regulations and the idea that if built properly, trail maintenance and environmental impact will be minimal.
