Park Begins Spraying for Exotic Plants

As a result of the recently completed Northern Great Plains Exotic Plant Management Plan (EPMP) and Environmental Assessment, staff at Wind Cave National Park have begun using herbicides to control Canada thistle.
The Finding of No Significant Impact (FONSI) for Integrated Pest Management was recently signed by NPS Midwest Regional Director Ernest Quintana and Acting Intermountain Regional Director Mike Snyder. Their signatures marked the end of nearly two years of effort by 13 regional park service areas to develop an integrated plan for controlling non-native plants.
Park Superintendent Linda L. Stoll, “The intent of this plan is to manage exotic plants to reduce their negative effects on native plant communities and other natural and cultural resources within the park and surrounding area. While we will continue to use manual, mechanical, prescribed fire, and biological controls in sensitive areas, such as over the cave, the use of herbicides adds an important tool in the park’s efforts to control a variety of non-native plants.”
Integrated Pest Management (IPM) is a decision making process that coordinates knowledge of pest biology, the environment, and available technology to prevent unacceptable levels of pest damage, by cost-effective means, while posing the least possible risk to people, resources, and the environment.
IPM employs integrated management practices rather than a single solution, wherever technically and economically feasible. The treatment options in this plan include cultural, manual/mechanical, biological control, chemical, and prescribed fire.

Winds caused by changes in barometric pressure are what give Wind Cave its name. These winds have been measured at the cave's walk-in entrance at over 70 mph. The winds at the natural entrance of the cave attracted the attention of Native Americans and early settlers.
