The DES Exotic Species Program coordinates activities associated with the control and management of exotic aquatic plants, as well as activities associated with the implementation of education programs and volunteer plant monitoring programs.

Exotic aquatic plants, such as milfoil and fanwort, have been a problem in New Hampshire lakes and ponds since the mid-1960s. Variable milfoil, by far the most wide-spread exotic aquatic plant in NH, was first found in Moultonborogh Bay in Lake Winnipesaukee. From there it has spread to infest more than 60 waterbodies. The program works mostly with submerged exotic aquatic plants, including variable milfoil (Myriophyllum heterophyllum), Eurasian milfoil (Myriophyllum spicatum), fanwort (Cabomba caroliniana), Brazilian elodea (Egeria densa), Hydrilla (Hydrilla verticillata) and water chestnut (Trapa natans), among other species. Other exotic plants, such as common reed (Phragmites australis) and purple loosestrife (Lythrum salicaria), although also of concern, are not addressed by the Program because they are not submerged aquatic plants, and are generally found more often in wetlands than in lakes or ponds.

Research Grants

Grant monies are available for innovative research projects by institutions of higher learning (i.e., colleges and universities). Research should focus on some issues associated with exotic aquatic plant management, control, biology, ecology or prevention, or other relevant projects. 

The performance period for the grant may be no longer than two years. Grant requests for subsequent phases of a research effort may be submitted.

  • Under RSA 487:26, eligible applicants include institutions of higher learning.
  • Research Grants may be awarded for any research on milfoil and other exotic aquatic plants remediation techniques, as provided in RSA 487:26.
  • Eligible projects include those that lead to developing scientific knowledge and understanding of milfoil and other exotic aquatic plant ecology, genetics or biology, and that lead toward new enhanced remediation techniques. 
    • Projects that seek to mechanisms for control or eradication of milfoil and other exotic aquatic plants are also favorable.
