It's Your Choice: Invasive Plant Control Options for Landowners

Thank you for your interest in being part of the project to control invasive plants on your coastal property. As invasive plants continue to cause ecological and economic concern, your choice to control is an important one and we are here to help. Together we can help ensure the Great Bay watershed remains the ecological gem it is.

There are a number of aspects to think about to ensure a successful control program. First, consider the size of the property and infestation, and pick your battles. Smaller infestations are typically easier to control and stay on top of than larger infestations. Second, determine if another infestation is located on an abutting property. Invasive plants know no boundaries, and can easily cross back onto your property, so again pick your battles to ensure success. Third, think about the habitat and ecology of the plant that you are controlling. These factors play key roles in control options and methods. Lastly, follow through with your controls and plan on continuing with your efforts, it may take a number of treatments, over the course of years for complete success. Once your control has been successful remember to complete the restoration planting with native plants.

We have developed the documents linked below to help you determine courses of action, control methods, and a successful outcome.

Introduction: This is a broad overview of invasive species as a whole, the threat to coastal NH and the work that has been started to confront invasive species.

Identification: The key to controlling invasive species is early detection and proper identification. These two presentations help the user to identify invasives:

Ecology: One key element in controlling invasives is knowing the ecology of the plant so that control methods may be tailored to site conditions, time of year, plant characteristics, etc.

Control: There are numerous methods (manual, mechanical, herbicide, etc.) of controlling invasive plants. The methods should be adapted to the specific plant that you are controlling.

Restoration: For success in controlling invasive plants, it is recommended to develop and follow a site plan. After plants have been removed by which ever method works best for you, restoration with native plants is recommended to ensure that the invasives do not re-colonize.

You are not alone: Invasive plants know no boundaries, and you are not alone in this endeavor. Invasives have been causing problems for landowners for many years, and will continue to cause problems unless action is taken. There may be money out there through the form of grants to help you on your project. The information contained here is just a small part of the massive amount of information out there. The informational sheet "further resources" will help you to go beyond what has been provided here, if you should need further assistance.
