Senior Associate Biologist



Emory Griffin-Noyes developed a love of conservation early in life and he began volunteering at a native plant nursery as a teen. Over the years he has worked to promote native species by removing invasive species (plant and animal), reforestation of native trees and establishment of critically endangered species. Emory has been working with the Hono o Na Pali Seabird Mitigation Predator Control team since 2016, and has developed into a skilled trapper with unmatched attention to detail. Along with his other duties, Emory manages our Barn Owl control programs and internal training, ensuring everyone is prepared for a day in the field.  Anyone hiking with Emory soon finds out that he can't contain his love for the native biota as he points out his favorite plants and animals observed along the trail. When not at work, Emory tends his gardens and orchids, spends time with his husband and pup, and cooks incredible dishes to share with friends and family.
