(DC) (Rock Creek Conservancy) Help the National Capital Region Invasive Plant Management Team, Rock Creek Park, and Invader Detectives survey for Corydalis incisa (Incised Fumewort). We will be hiking along the creek on trails south of Peirce Mill and using pin flags and iNaturalist to record any instance of the plant that we find. Corydalis incisa was first detected in Bronx County, NY in 2005 and has spread rapidly across the East coast ever since. C. incisa forms dense populations that suppress native plant growth. Our goal is to search for and understand the extent of both of this species so we can assess potential responses.
