CORVALLIS, Ore. (Sept. 12, 2007)- An invasion of American beach grass is under way along the Oregon coast, threatening to change dune ecology and reduce the ability of dunes to protect roads, property and towns from coastal storms.
Sea Grant-funded scientists at Oregon State University have documented a slow but steady takeover by this beach grass, an invasive species. They found that protective “foredunes” covered by the new grass species are only about half as high as those created by the European species of grass that were formerly dominant.
