The challenges that invasive species pose to the natural areas we value so much in the city
The past few summers people have flocked to the bluff above Oaks Bottom to admire the striking purple flowers that blanket the wetland. Although these flowers, known as purple loose strife
, are beautiful, they should not be there. In fact they are a noxious invasive weed that is choking out the native wetland habitat. But getting rid of purple loose strife and all the other exotic invasives that spread throughout urban natural areas is not an easy task. On this episode of Locus Focus we talk with Portland Parks & Recreation ecologist Mark Wilson
about the challenges that invasive species pose to the natural areas we value so much in the city.
