Short-term disturbance to sagebrush/annual grassland and sagebrush/perennial grassland are considered long-term disturbance and are included in this table disturbance. 2 Total long-term disturbance to vegetation does not include disturbance to agriculture, developed/road/fire break, or water body. Acres of short-term disturbance are presented in the discussion section for each route segment.
