Purging the Spurge

The Canadian Globe and Mail published this story about Leafy spurge (Euphorbia esula) problems in Manitoba. The species, which is not only toxic to grazing animals, but to neighboring plants as well, has taken over acres and acres of agricultural land since it first arrived from Asia in the late 19th century. The Nature Conservancy, which owns a big chunk of prairie land infested with leafy spurge, has been experimenting with using insects as a biological control to keep populations from spreading further. The article also contains some general information about invasive species.
