The Invasive Species Weeds Subgroup focused on flowering rush, an invasive aquatic species the spread after escaping from cultivation in the ornamental trade and is now found across 17 of the Northern U.S states and nearly all Canadian provinces. First documented on Flathead Lake, Montana in 1964, the spread of flowering rush now encompasses thousands of acres across the Pacific Northwest in habitat that is considered essential for the spawning of a number of salmonid species.

The group published this Flowering Rush White Paper in January 2015.

The group sponsored the Flowering Rush Symposium conducted at the Northern Rockies Invasive Plant Council Conference in February 2014 in Airway Heights, Washington.
