Island Marble

Join Sarah Hanson, Executive Director of On Sacred Ground, to learn about the history of Island Marble Butterfly as well as recent changes for its recovery plan due to its listing as an endangered species in 2020. Walt Andrews, Island Marble Butterfly Volunteer Program Coordinator, will share how volunteers will play a key role in supporting unique and specific habitat needs of Island Marble, as well as where the volunteer program is headed.

Sarah Hanson

Sarah has been working as a conscious land steward for 25 years. She directed trail and wilderness restoration crews in varied ecosystems from 2003-2012 for Student Conservation Association, Pacific Crest Trail Association and Washington Trails Association in Alaska, Washington, Oregon, California, Arizona, Utah, South Carolina and Georgia. She has been a WWOOFer in Costa Rica, Ecuador, Italy and Senegal, learning organic gardening techniques, and is a certified permaculture designer. Sarah was the first program director for the San Juan Island Conservation Corps for 5 seasons from 2012-2016, working with public lands agencies, local non-profits and Coast Salish tribes. She helped pave the way for a Coast Salish Youth Conservation Corps, and served on the San Juan County Agricultural Resources Committee from 2020-2022. She has a B.S. in Geology/Geophysics from Western Washington University, moonlights as a healer, writer, sailor, DIY tinkerer, and has studied indigenous healing with the Q’ero tribe in the high Andes of Peru. Sarah has called San Juan Island home since 2001.

Walt Andrews

Walt is an ecologist who has worked in research, conservation, agricultural science, outreach, and education. He has experience working with a wide variety of federal, state, and local land managers and with these imperiled species: Hawksbill Sea Turtle, Bull Trout and the Marbled Murrelet. Walt is excited about the possibilities in front of us, for islanders to rally for our endemic Island Marble Butterfly by creating and maintaining habitat with the volunteer program. Walt also works at WSU San Juan County Extension as a Research Assistant, balancing field work with data analysis, presentations and writing, most recently working on wireworms and pasture trials. He enjoys exploring the mountains and islands offer and thoroughly appreciates the scientific process.

Wednesday – December 7 at 6 pm – David Droppers and Phyllis Reed
Mountain Loop Highway: How a Project on the National Forest Evolved

Video of this meeting is available at:

Johnson’s hairstreak (Callophrys johnsoni)

In this tag-team presentation, David Droppers, along with Phyllis Reed, North Zone Wildlife Biologist with the Mt. Baker-Snoqualmie National Forest, will present updates from his final season of researching butterflies on the Mountain Loop Highway on the Darrington Ranger District. Phyllis will cover how she met David and how the Forest Service’s responsibility toward habitat management and pollinators lead to projects such as his. Learn about the various issues concerning pollinators, the goals and challenges that the Forest Service faces in meeting these responsibilities, the importance of citizen science, and how you might be able to help.


Wednesday – November 2 at 6 pm – Dave Nunnallee –
“Buckwheats and the Butterflies that use them”

Dave Nunnallee has long had an intense interest in natural history, including birds,
butterflies, dragonflies, native plants, and natural history in general. A retired engineer
and co-founder of the Washington Butterfly Association, he led butterfly field trips in the past
and was co-author with David James of “Life Histories of Cascadia Butterflies”. He has
had a particular interest in buckwheats, with an emphasis on those utilized as host
plants by butterflies.

Wednesday – October 5 at 6 pm – John Acorn –
“The Ways in which Butterflies Fly”

Video of this meeting is available at:

Description: Butterflies don’t just flutter, and birds don’t merely flap. They also hover, glide, soar, burst, stoop, and perform a remarkable suite of additional flight styles, all in accordance with their sizes, shapes, and situations. Join me for an explanation of bird and butterfly flight that will focus on the different “modes” that these animals use while in the air. I promise to go easy on the physics, and also to give you some tips that might enhance your wildlife viewing experience, and encourage you to make more use of that slow-motion setting on your camera or smartphone.

Bio: John Acorn is a biologist and naturalist, and he teaches at the University of Alberta. John has been a lifelong resident of Edmonton, and he is best known for his television series Acorn, The Nature Nut, and as the author of some twenty books on natural history subjects.
