Forest Ecologist Lyndia Hammer fell in love with the Klamath Siskiyou Ecoregion in the mid 90’s while surveying for martens, fishers, and Marbled Murrelets in the northern Siskiyou Mountains. Since then she has both taught and attended classes at the Siskiyou Field Institute, and has completed degrees in Biology and Forestry from Southern Oregon University and the University of Missouri – Columbia, respectively. Lyndia feels honored to work with the talented and committed Staff and Board of Directors at SFI to make outdoor school and natural history programming available for all.

Julie holds degrees from the University of Texas in Mathematics (B.A. 1970) and Computer Science & Educational Psychology (M.A. 1974). In 1976, after a brief stint as a systems programmer at IBM, Julie moved to Josephine County to work as a river guide on the Wild Rogue River. In 1983 she began a 30-year career in forest and river conservation, working for three Rogue Valley nonprofits: Headwaters, Siskiyou Regional Education Project, and Geos Institute. Her roles included public outreach, media relations, event coordination, and fundraising. She was awarded the Conservationist of the Year Award from Oregon Wild (1992) and the Environmental Hero Award from the Wilderness Society (1998). Julie is now retired in Ashland and still running rivers for fun. We are lucky to welcome her to our team.

Phoebe grew up in Ashland Oregon after her family moved from the Illinois Valley, where they lived for 20 years. Her parents, Dr. Jim Shames and Heidi Parker, helped found the Takilma Peoples’ Clinic (now the Siskiyou Community Health Center). Growing up in the Klamath Siskiyou Ecoregion sparked Phoebe‘s love for the outdoors, and she is now getting her doctorate in environmental science, policy, and management at UC Berkeley. For her dissertation research, she returned to Josephine County in order to do conservation-relevant research and give back to her community.
