The whine of chainsaws and rumble of wood chippers are echoing around the shores of Pearl Harbor. Work crews are clearing an invasive species of mangrove from the shoreline and coastal streams that empty into Hawaii's most famous body of water. "Pearl Harbor is being choked out by red mangrove," says Amanda Millin, a field crew manager overseeing a team of five. Millin notes that in most tropical ecosystems, mangroves provide a variety of environmental benefits, including sequestering carbon, controlling erosion control and fostering biodiversity.
