Status and Strategy for Flowering Rush Management

Invasive flowering rush (Butomus umbellatus L., hereafter FR) has invaded the shores of Michigan waterways since the early 1900's (Core 1941; Stuckey 1968; Anderson et al. 1974). This document was developed by Central Michigan University and reviewed by Michigan Departments of Environmental Quality and Natural Resources for the purposes of: * Summarizing the current level of understanding on the biology and ecology of FR. * Summarizing current management options for FR in Michigan. * Identifying possible future directions of FR management in Michigan. This document used the current information available in journals, publications, presentations, and experiences of leading researchers and managers to meet its goals. Any chemical, company, or organization that is mentioned was included for its involvement in published, presented, or publically shared information, not to imply endorsement of the chemical, company, or organization.
