"Join Desert National Wildlife  Refuge staff and volunteers for a morning of habitat restoration on the largest wildlife refuge in the lower 48 states. This event will provide volunteers with experiences related to invasive species management, planting native plants, and trail enhancements. This is a great opportunity to become more familiar with native flora and fauna, and meet other community  members that share  similar passions. To join, email the refuge manager Michael Matthews at michael_matthews@fws.gov so that we know to expect you and to provide additional information. Meet at the front entrance of the Corn Creek visitor center."
