Pretty flowers, invasive weeds
The Sandy River Basin Watershed Council, Clackamas County Soil and Water Conservation District and hundreds of volunteers are striving to remove Policeman's Helmet from the area.
This invasive weed can grow up to 8 feet tall and has a handy mechanism for spreading its seeds: exploding seed pods. When the pods dry, seeds erupt from the pod, landing as far as 20 feet away.
Policeman's Helmet's thick stocks displace native vegetation and disrupt habitats.
When the annual plant dies down in cold weather, it leaves loose soil that can erode in storms.
Policeman's Helmet thrives along streams and disturbed areas.
The Clackamas County Soil and Water Conservation District is concerned about new infestations of Policeman's Helmet along the Clackamas River.
In a recent press release, the Clackamas Conservation District requested that local sitings of Policeman's Helmet be reported at 503-210-6000.
