For the second consecutive year, volunteers from CITGO Petroleum Corporation, Houston Audubon Society and the Galveston community converged on the Smith Oaks Sanctuary in High Island to plant trees and remove invasive vegetation. The Houston Audubon Society-owned sanctuary, which protects 177 acres of field, woods, wetlands and ponds, is still recovering from damage inflicted over years of hurricane seasons and needs help in order to protect the many species of migratory birds who call it home.
