Our evaluation included roads programs at the Bureau of Indian Affairs (BIA), National Park Service (NPS), U.S. Fish and Wildlife Service (FWS), and the Bureau of Land Management (BLM). The Bureau of Reclamation (BOR) also manages roads; however, we excluded BOR from our evaluation due to its small roads inventory. (See Appendix A for a complete list of abbreviations and acronyms used throughout the report and Appendix B for our scope and methodology).
