Managing Invasive Plants

Why should I care about invasive plants?

Invasive plants out-compete and displace native plants.   They reduce biodiversity and wildlife habitat by changing cover, nest sites, water quality, and foods.  Invasive plants can cause human health problems too.  

How do I know what is an invasive plant?

How do I go about addressing invasive plants on my property?

Knowing where to start can be a bit overwhelming.  Fortunately, NH Fish and Game created this guide to planning successful projects – Picking Our Battles.

What methods are available for controlling invasive plants on my property?

There are a lot of good resources available to help you select the best method for controlling invasive plants.  Be sure to consider a program of integrated pest management.  Treating invasive plants near wetlands requires some additional consideration so read the label on all over-the-counter pesticides you purchase and use.

What should I do with the invasive plants after I remove them from my property?

Did you know it is illegal to collect, transport, sell, distribute, propagate, or transplant prohibited invasive plant species?  Have a plan for handling vegetative material.   Information from the UNH Cooperative Extension can help:  Disposing of Non Native Invasive Plants.

Did you know that the Department of Public Works implements a program of Japanese Knotweed treatment along town roadways.  If you know of an infestation, you can report it online through the Report a Concern link. 

Speaking of Japanese knotweed, this publication provides advice specific to Japanese knotweed control.   

Where can I learn more?

The UNH Cooperative Extension and the State Department of Agriculture, Markets, and Food provide lots in useful information about invasive plants.
