On a recent Sunday morning, Senior Airman Sha’Angelo Farley, a Physical Science Technician with the U.S. Air Force’s 15th Maintenance Squadron at Joint Base Pearl Harbor-Hickam (JBPHH), headed to Haiku Valley on the windward side of Oahu where he joined other volunteers for cultural service work. He removed invasive species, planted native plants, and learned about Native Hawaiian culture and practices from the Koolau Foundation, which sponsors the bimonthly workday and learning program. “It was a great organization to work with,” he said, adding that he was grateful for the opportunity to give back to the community.
