CHEYENNE, Oklahoma – On Sunday, August 26, 2018 at 2:00 PM walk the Dust & Fire Trail with local prairie grasses expert Laurie Boerngen of the USDA. Human immigration and warfare were not the only big impacts to the Great Plains 150 years ago. With Europeans came cattle and seeds that sparked a growth of weeds that brought about the extinction of many plants and animals native to North America. Native plant populations are still in danger of extinction today. Join us and our special guest lecturer as we walk the Dust & Fire Trail and learn the detail of the plants of the prairie, then and now.
