ATA is a non-profit Oregon group formed by community residents to develop a system of hiking, mountain biking, and equestrian trails in the mountains and meadows of the Applegate and Rogue valleys. We cooperate with public land agencies, community organizations, and private landowners to preserve and connect historic trails for the broader community and generations to come.

Our aim is to conserve our valley's valuable resources, the land, the views, and the biodiversity,

for the non-motorized enjoyment of people of all ages and ability.

Our Mission

We create and preserve non-motorized trails in the Applegate Valley, providing recreational and educational access to public lands while protecting our natural resources.

Board of Directors

​​​​David Calahan, Chair (center): His love for the outdoors drove this native Oregonian to search for and find an isolated eighty-acre homestead on the sunny side of Wellington Butte over forty years ago. David shares this little piece of heaven with his wife, Barbara Kostal. Retirement from the Medford Fire Department allows him to pursue his passion for renewable energy, hiking trails and the ART.

He owns and operates his own business, Green Path Landworks, which specializes in forest restoration and land management services. At home, Josh, his partner Brianna, and their kiddos Zoey and Carys, live at lovely Peach Rock Farm along the Applegate River in Provolt with their twenty-three chickens, two cats and nine hundred fruit trees. He enjoys camping, hiking and backpacking in the mountains of the Klamath-Siskiyou region. Contact Josh at

Stuart Osmus, Director (right): Stuart has lived in the Applegate Valley since 2014. He has spent much of his life outdoors with hiking, backpacking, camping, fishing and photography being some of his passions.
