Erin Arnsteen

Western Program Coordinator (she/her)

Erin supports MJV’s western U.S. conservation efforts to help monarch butterflies and other pollinators. She works across MJV program areas of education, science, habitat, and partnerships. In particular, she uses her technical expertise in entomology and native plant ecology to support agricultural landowners and other regional stakeholders with the mobilization and expansion of habitat conservation in all landscapes. Erin earned a bachelor’s degree in fine art and a master’s degree in education both from Colorado College. Erin has studied entomology for most of her life and is truly passionate about invertebrates and conservation. She founded the Western Monarch Society of Napa County and has grown and given away thousands of native milkweed plants with the goal of restoring native habitat for western monarch butterflies and other native pollinators. In her spare time, she enjoys observing the wildlife in her native pollinator garden, hiking, and spending time with her husband and two cats.
