The Royal Oak Garden Club is hosting an invasive species presentation by the Oakland County Invasive Species Management Area (CISMA). In Oakland County, invasive species can reduce property values, damage infrastructure, create public safety hazards and degrade natural areas. CISMA is an organization that works to manage invasive species that are not native to Michigan, and whose introduction causes harm, or is likely to cause harm to Michigan’s economy, environment, wildlife or human health. Space is limited; RSVP to royaloakgardenclub@gmail.com.
