Invasive Species

Two J. Clark Salyer NWR seasonal employees collect spurge beetles for relocation. An invasive species is one that is not native to an ecosystem and which causes, or is likely to cause, economic or environmental harm or harm to human health.

J. Clark Salyer NWR uses a combination of chemical, mechanical, and biological treatments to help control invasive species.  Chemical treatments vary depending on target species and habitat type.  Mechanical treatments include haying, grazing, and prescribed fire.  Flea beetles are used for the biological control of leafy spurge.  Leafy spurge, Canada thistle, Absinth Wormwood, and  Yellow Toadflax are the main invasive species of concern at J. Clark Salyer NWR.
