To address mounting concerns over invasive plants and the role NHDOT activities play in the spread of these plants along roadsides, Best Management Practices (BMPs) have been developed with input from Maintenance Districts, the Roadside Development Section, the Bureau of Construction, and the NH Department of Agriculture. Implementation of these BMPs will help prevent the spread of invasive plants caused by maintenance and construction activities.

Fig Buttercup (Ficaria verna, formerly Ranunculus ficaria) is an early-blooming perennial with origins in Europe and northern Africa. It is also called Lesser Celandine, and it is sometimes confused with Marsh Marigold (Caltha palustris). More recently, its behavior has transitioned or is in the process of transitioning to that of an aggressive invasive species that threatens bottomlands throughout its adopted range. Even after its invasiveness was recognized, many people did not anticipate that it would behave invasively in the South, as it has begun to do. Be a Citizen Scientist— We are asking you to help us scout areas near you where it is likely to be found, so that emerging infestations can be documented, treated and monitored.

In 1997, the Colorado Legislature established the Colorado Noxious Weed Management Fund to provide additional financial resources for on-the-ground noxious weed management. Organized private interests, conservation districts, municipalities, and counties have been eligible to apply for assistance provided that awarded funds are used to enhance weed management efforts within the State of Colorado.
