The present direction for assessing and monitoring soil quality for National Forest System Lands at the National and Regional levels is currently undergoing review for the purpose of incorporating new science and technology. This subject was discussed at the Southwestern Region Watershed and Air workshop held April 24–27, 2012. Previous direction that was incorporated under R3 Forest Service Handbook (FSH 2509.18) will soon be migrated to a Regional supplement within FSM 2550.
