A Japanese Knotweed (Polygonum cuspidatum) Inventory of the Cuyahoga River and Selected Tributaries within Cuyahoga Valley National Park
Dengg EL. 2004. A Japanese Knotweed (Polygonum cuspidatum) Inventory of the Cuyahoga River and Selected Tributaries within Cuyahoga Valley National Park
An inventory of the invasive non-native plant Japanese knotweed (Polygonum cuspidatum) was conducted in Cuyahoga Valley National Park during the late summer of 2002 to identify infestation areas. Four hundred and seventeen separate infestations were documented, covering approximately 78 acres. Infested areas tended to contain very few other species, with an average of 50 to 75 percent of each infestation area covered with knotweed. Data collected during this inventory has been integrated into a comprehensive invasive species database being developed at the park. The database will be used to create distribution maps and prioritize invasive species populations for management action that will enable resource managers to plan control actions accordingly. Recommendations include a monitoring effort every 3-5 years and annually when conducting control efforts.
