Our Staff

We are a group of people committed to the power of the promise of the Wilderness Act and to those within and outside the federal government who strive to keep that promise. There is one National Wilderness Preservation System. There are four agencies that manage it. We believe it makes sense to work across Department and agency boundaries to develop comprehensive, interagency solutions to wilderness stewardship issues that directly meet the needs of the field.

Josh Nadas

Josh Nadas is the Acting Director of the Arthur Carhart National Wilderness Training Center. He comes to Carhart from the Forest Service Legislative Affairs Program. He has worked on a number of wilderness-related bills while with the agency including Senate Resolution 708, which commemorated the 100th anniversary of the designation of the Gila Wilderness. Josh has a passion for wilderness and recreation and is focused on the nexus between land management and the laws and policies established by Congress related to how people protect and enjoy public lands. Prior to joining the Forest Service, Josh worked for the National Park Service in their Legislative Affairs Program, as a park planner, and for the Rivers, Trails, and Conservation Assistance (RTCA) program. During his work with the RTCA National Office Josh staffed the Federal Interagency Council on Outdoor Recreation, where he developed the initial memorandum of understanding framework that continues to guide that interagency council.

Josh grew up camping, hiking, rock climbing, mountain biking, and rafting all over the east coast of the United States. His first wilderness experience was to Dolly Sods Wilderness in West Virginia on the Monongahela National Forest while working at the University of Maryland Outdoor Recreation Center as a trip leader.

James Sippel

James Sippel is the Bureau of Land Management Representative at the Arthur Carhart National Wilderness Training Center and on the staff of the BLM's National Conservation Lands Division in the Headquarters Office. James began his wilderness career in 1991 in the BLM as a Wilderness Ranger with Wilderness Study Areas. He has held federal natural resource management positions in California, Nevada, New Mexico, Oregon, and Washington. James came to the Carhart Center in 2015 from the New Mexico State Office of the BLM where he was the region's National Conservation Lands Program Lead (including wilderness). James has worked on policy development for the BLM, including contributions to Manual 6340 (Management of Designated Wilderness) and a major role in Manual 6330 (Management of Wilderness Study Areas). Though he recognizes that important work occurs at a desk, he believes that the measure of our work's relevancy is the condition of the land, and with that in mind, is dedicated to assisting field staff. James' first encounter with Wilderness was at age 12 in the John Muir Wilderness near his childhood home of Ridgecrest. That was the start of a life-long interest in desert, forest, and alpine Wilderness. Having spent over 400 nights camped in the Wilderness, a majority of that with his family, James dedicates much of his career and free time to the subject. He believes that John Muir was right, that "going to the mountains is going home." James earned a Bachelor of Liberal Arts from Prescott College, Arizona, and a Master of Arts Interdisciplinary Studies in Forest Resources, Rangeland Resources, and Environmental Policy (thesis on wilderness management) from Oregon State University.
