The Invasive Species Committee is a volunteer group of eleven appointed members who consider and evaluate the adverse environmental and economic effects of invasive terrestrial plants, insects, and fungal species upon the state. The efforts of the Committee include recommending means by which the state shall address and minimize such adverse effects, including promoting research and educational activities to protect agriculture, forest, wildlife, and other natural resources of the state and human health; and prevention and control of the spread of invasive species in the state (refer to RSA 430:51 through RSA 430:57). It is illegal in New Hampshire to knowingly collect, transport, sell, distribute, propagate or transplant any living or viable portion of any listed prohibited invasive plant species including all of their cultivars, varieties, and specified hybrids.
