The Columbia Basin CWMA is focused on cooperative management of flowering rush, so sharing information is key to this effort. There are a variety of resources specific to flowering rush that are provided here. If you have a resource not listed here that would provide additional information to resource managers, contact the Columbia Basin CWMA coordinator.
This is a great source of information that documents the current monitoring efforts, and early detection work within the Columbia Basin and in the immediate vicinity. The database is hosted by Washington Department of Agriculture and created from data provided from partners across the Pacific Northwest. Access the database.
Many partners across the Pacific Northwest have examined strategies to control flowering rush infestations, and document ecological interactions. The reports provided here contain valuable information to better understand flowering rush. If you have specific questions regarding information in these reports, contact the principal investigator indicated in that document.
