RT Journal Article SR Electronic T1 Control of Knotweed and other invasive species and experiences restoring native species in the Pacific Northwest US JF Native Plants Journal JO NATIVE PLANTS JOURNAL FD University of Wisconsin Press SP 20 OP 26 DO 10.2979/NPJ.2006.7.1.20 VO 7 IS 1 A1 Roberta Davenport YR 2006 UL http://npj.uwpress.org/content/7/1/20.abstract AB Invasive knotweed (Polygonum L. [Polygonaceae]) species are a significant threat to native ecological communities that occur in riparian areas and other vulnerable habitats. This project applied practical methods to control Bohemian knotweed (Polygonum x bohemicum). This species was controlled for 2 y prior to restoring appropriate native species for the Chehalis River Surge Plain Natural Area Preserve in Washington State (US). The invasive species Himalayan blackberry (Rubus discolor Weihe & Nees [Rosaceae]), scotsbroom (Cytisus scoparius (L.) Link [Fabaceae]), and reed canarygrass (Phalaris arundinacea L. Raeush [Poaceae]) were also controlled.
