Montana Invasive Species Council.
Montana’s economy could see more than $230 million in annual mitigation costs and lost revenue if invasive mussels become established in the state, according to a report released by the Montana Invasive Species Council (MISC). Commissioned by MISC and completed by the University of Montana Flathead Biological Station, the economic impact study provides “a snapshot of projected direct costs to affected stakeholders dependent on water resources,” said Bryce Christiaens, MISC chair. “It does not reflect the total economic impact to the state, which would be considerably higher.” View a one-page fact sheet (PDF | 484 KB) or the full report (PDF | 4.0 MB).

Ohio Invasive Plants Council.

In September of 2014, the Ohio General Assembly granted the Ohio Department of Agriculture (ODA) the exclusive authority to regulate invasive plants species. Under the law invasive plants are defined as plant species that are not native to Ohio whose introduction causes or is likely to cause economic or environmental harm, or harm to human health as determined by scientific studies. After nearly two years of stakeholder outreach, new rules have been established and are effective as of January 7, 2018.

Montana Invasive Species Advisory Council.
Prepared by: Creative Resource Strategies, LLC. In 2015, the Council contracted with Creative Resource Strategies, LLC to conduct an assessment and gap analysis of Montana's invasive species programs. This report documents the outcomes of that assessment and analysis, and includes an articulation of key gaps as well as a set of recommendations to refine strategies and approaches, and enhance efficiencies, to address invasive species. It is important to recognize that the information from survey respondents represents a snapshot in time—the 2015 fiscal y ear—for each contributing entity. In addition, the information obtained from survey respondents was, in numerous cases, incomplete, and in some cases, not accurate. Nevertheless, the information obtained is of value to identify gaps and inform a set of recommendations.

Piedmont Environmental Council.
Wavyleaf basketgrass is a new exotic grass rapidly moving into forests and meadows in Virginia and Maryland. The Piedmont Environmental Council is part of a Task Force committed to stopping this plant before it forms a thick carpet on our forest floors, crowding out native plants. If you think you spot wavyleaf basketgrass, please report your sighting.
