About the Applegate Trails Association

The Applegate Trails Association (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 of the Applegate Valley.

ATA is cooperating with public land agencies, community organizations, and private landowners to preserve and connect historic trails for future generations.

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 levels of ability.

Our Mission

The mission of the Applegate Trails Association (ATA) is to create and preserve non-motorized trails in the Applegate Valley, providing recreational and educational access to public lands while protecting our natural resources.


ATA Board of Directors

David Calahan, Chairman

His love for the outdoors drove this native Oregonian to search 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. Contact David at david@applegatetrails.org.

Mike Kohn, Treasurer

Mike lived in the Applegate Valley from 1974 through 2003 serving on the Applegate and Three Rivers School Boards. He now lives in Medford, but the Applegate will always be in his blood. He is an avid hiker. Mike owns Home Comfort Hearth and Chim-Chiminey Sweepers in Grants Pass and Phoenix. Contact Mike at mike@applegatetrails.org.

Joshua Weber, Director

Josh has called the Applegate Valley home since 2007. He owns and operates his own business, Green Path Landworks, which specializes in forest restoration and land management services. He lives on a creek-side homestead in the country and enjoys camping, hiking and backpacking in the mountains of the Klamath-Siskiyou region. Contact Josh at  josh@applegatetrails.org.

Diana Coogle, Director

An avid, if not rabid, hiker, back-packer and cold-water swimmer, writer Diana Coogle grew up in Georgia but has lived in the mountains above the Applegate River for more than forty years. In 2012, she received a Ph.D. in English from the University of Oregon. She teaches writing at Rogue Community College and blogs at dianacoogle.blogspot.com.

Luke Ruediger, Director

Luke Ruediger grew up in Southwest Oregon and began exploring the region’s unique habitat and terrain at an early age. Living with his wife, Suzie, in a remote, off-grid homestead at the foot of the Siskiyou Crest, Luke enjoys long, rugged bushwhacks and backpacks, endemic wildflowers, and big tree hunting. Fascinated by the region’s beauty and diversity, Luke has long worked to preserve, restore, and protect the ecological integrity of the Siskiyou Mountains, through both environmental activism and land stewardship. Luke published a hiking guide for the region titled, The Siskiyou Crest: Hikes, history and ecology, in 2013 and currently writes a blog exploring ecological issues in the Siskiyou Mountains (www.thesiskiyoucrest.blogspot.com). Luke is also an active member of the Applegate Neighborhood Network and the Klamath Forest Alliance. Contact Luke at  luke@applegatetrails.org.

Lily Kaplan, Director

Lily has been an avid hiker, camper, gardener and nature lover since early childhood, growing up beside acres of cattle and sheep, grazing lazily along bubbling creeks, and nestled amid the majestic hardwoods of the east. Clambering over boulders among maple, birch and oak or making nests in groves of sugar pines was a favorite pastime, eventually leading Lily into her first career as a horticulture therapist. Growing spring bedding plants in greenhouses while nurturing the human spirit eventually turned into decades of leading soul-searchers on earth-wisdom retreats in wild settings and pilgrimages to sacred sites in southwest desert landscapes. Later, as the director of the non profit, Camps-In-Common, operator of Oakland Feather River Family Camp in the low Sierras of northern California, Lily introduced inner city youth to the wonders of wilderness and the beauty of the great outdoors. After the life-altering experince of losing three close family members in one year Lily founded a non profit dedicated to her sister and brother in law called The Spirit of Resh Foundation. Feeling the urgency that encountering death brings to life, Lily decided that it was now or never to live her truest life, and chose to relocate from the beautiful-but-too-busy San Francisco Bay Area to the stunningly-spectacular-Applegate Valley, where she lives with her husband, Seth and their two animal companions, Shayna and Sweet Pea, tends her garden and gives what she can to her local community.
