Date of U.S. Introduction

Invasive European strains probably introduced during the 1800s (Saltonstall 2002)

Means of Introduction

Possibly through ships' ballast (Saltonstall 2002)

Impact

Crowds out native species (Tewksbury et al. 2002)

  • Minnesota DNR Classifies 13 Invasive Plants, Animals as Prohibited

    • Feb 20, 2024
    • Minnesota Department of Natural Resources.

    • The Minnesota Department of Natural Resources has classified 13 high-risk invasive aquatic plants, fish and invertebrates as prohibited invasive species. The DNR classifies invasive species as prohibited to prevent their introduction and spread in Minnesota and to protect the state’s environment, economy, natural resources and outdoor recreation. It is unlawful to possess, import, purchase, transport or introduce prohibited invasive species, except under a DNR-issued permit for disposal, decontamination, control, research or education.

      The prohibition on 12 of the 13 species is effective immediately, with publication of the new listings in today’s State Register. Jumping worms will be prohibited invasive species effective July 1, 2024, to provide additional time for outreach to businesses and others who may be impacted by the rule change. A complete list is available on the DNR invasive species laws website.

  • What Makes This Invasive, Non-Native Reed Grass Thrive in the Wetlands?

    • Apr 6, 2022
    • Louisiana State University.

    • The Mississippi River Delta is home to the world’s largest contiguous swath of Phragmites australis, or more commonly known as the common reed. But the plant that can grow to nearly 20 ft. and has been a critical component in stabilizing the state’s coastal erosion is not actually native to Louisiana—well, not entirely. There are multiple P. australis genotypes. P. australis subspecies (ssp.) americanus is the native subspecies in the U.S. and Canada. However, Phragmites australis ssp. australis originated in central Europe and was subsequently introduced to the U.S. where it is now considered to be one of the most problematic invasive species in North America. In a newly published study in Molecular Ecology and recently featured in an edition of The Scientist, LSU researchers collaborated with Tulane University and the U.S. Geological Survey to study the genomic bases of P. australis and to investigate what exactly makes the invasive reed grass subspecies thrive in wetlands, in comparison to its native counterpart.

  • Great Lakes Phragmites Collaborative

    • Great Lakes Commission.

    • The Great Lakes Phragmites Collaborative is a network of agencies, organizations and citizens who are engaged in Phragmites in some way, including management, research and communication. The Collaborative was established to facilitate communication among stakeholders across the region and serve as a resource center for information on Phragmites biology, management, and research.

      See also: Phragmites Adaptive Management Framework (PAMF) Strategic Plan (2020-2026). This strategic plan will guide successful implementation of PAMF by setting program-specific goals, objectives, and measures for the next five years. The PAMF core science team that developed the plan includes representatives from the Great Lakes Commission, U.S. Geological Survey, and University of Georgia.
