San Diego has itself a case of invasive mangroves. For a type of tree best known as a component of rare and treasured wetland ecosystems, this may surprise some. Yet several decades ago, someone decided to plant gray mangroves (Avicennia marina) in Mission Bay, California, and according to this story from the San Diego Union-Tribune, they won't go away. Apparently the species was thought to have been eradicated from the bay over ten years ago, but is now back with a vengeance. A team of volunteers led by the Audubon Society is currently working at removing the trees, in the hopes of creating more suitable nesting habitat for endangered birds that frequent the wetland.
