Otey-Grisely Forest Nature Preserve and Grisley Woods Land and Water Reserve are located in Williamson County, just north of Marion and Pittsburg. Friends of Otey-Grisley are planning a workday to remove invasive plant species from the site so we can help restore an ecological diverse area and help protect native habitats for threatened and endangered birds.<br/><br/>Please be advised to dress for the weather, for work outside, and to bring water. Snacks will be provided! All are welcome to join and be a Friend to Otey-Grisely Forest Nature Preserve.
