Watershed Restoration and Outreach Specialist

Alisha was fortunate to have grown up on the island of Maui, a place where finding nature often means stepping outside your door. She spent most of her childhood hiking, going to the beach, surfing, and snorkeling. Her passion for the environment led her to pursue a Baccalaureate of Science in Global Environmental Science at the University of Hawaiʻi Mānoa. Throughout her undergraduate career she conducted research with the Hawaiʻi Coastal Geology Group. Her thesis project analyzed changing shoreline positions and beach widths along the east-facing shores of Oʻahu to develop a historical planning context. After graduating, she interned with Planning Consultants Hawaiʻi, LLC, where she assisted planners in preparing a scoping plan and a master plan for Līpoa Point and Kanahā Beach Park, respectively. Alisha is excited to be working with the Tuolumne River Trust, as watershed restoration is a critical problem we now face in California. She is looking forward to learning more about California’s watershed environment and make an impact to protect California’s rivers for future generations.

Watershed Education Specialist

After looking over my resume, a good friend of mine once remarked, “Wow. You’ve taken the scenic route, haven’t you?” I graduated from UC Riverside in 2009 with a degree in Anthropology, but it’s taken me 8 years (and 13 jobs, by my most recent count) to finally figure out that I’d like to pursue a career in environmental conservation. In the past 7 years I’ve been fortunate enough to live in Washington, Maine, Colorado, and Alaska—all incredibly beautiful places! And in 2013 I hiked the Pacific Crest Trail, a truly life-changing experience, but I still felt directionless. I didn’t find what I was looking for until this past summer, when I lived in the Eastern Sierra. This mountain range that I’ll be working alongside for the next 11 months is unique and awe-inspiring; it’s the first place where I’ve wanted to put down roots in my short but itinerant life. If I can’t be outside, I like to spend my time cooking, eating, and indulging in all things Harry Potter.

Wildfire Restoration Specialist

Born and raised in Colorado, Ellyse spent her childhood as a full-time adventurer, feeding her sense of wonder throughout the Rocky Mountains. She loves camping, hiking, backpacking, rock climbing, and snowboarding but truly discovered her passion when she took a geology class at Colorado State University which led her to discover the science and study of the natural world she so adored. With a bachelors degree in Natural Resources Management and a double minor in Global Environmental Sustainability and Restoration Ecology she is now finding her niche in the real world. Since traveling the west coast and working in urban forestry and gardening she is looking forward to getting more rural and back into the mountains and forests that so inspired her once before. She is extremely excited to embark on a new adventure in the Sierra Nevada to fulfill her dreams of science and pursue new explorations and experiences.
