Boaters: You Can Help STOP AQUATIC HITCHHIKERS!
CONCORD, N.H. -- If you enjoy boating or paddling on New Hampshire's beautiful waterways, the New Hampshire Fish and Game Department is asking for your help in stopping the spread of invasive plants and animals. Exotic aquatic species like milfoil can easily be transported on boats, motors, trailers, fishing equipment, bait buckets, diving gear and other aquatic recreational equipment. These "aquatic hitchhikers" can take over lakes and ponds, choking waterways with explosive growth, fouling intake and discharge structures, lowering lakefront property values, and possibly harming native fish, plants and insects. Once established in a waterbody, they are nearly impossible to eradicate.
New Hampshire already has five different species of
invasive aquatic plants in its waterways -- two kinds of milfoil (variable
and Eurasian), fanwort, water chestnut and Brazilian elodea. In all, 60
New Hampshire lakes, ponds and rivers are infested to date, according
to Jody Connor, Director of the Department of Environmental Services (DES)
Limnology Center, which tests biological samples from freshwater lakes
around the Granite State. Of these, 54 waterbodies are infested with milfoil,
including a new infestation last summer at Scobie Pond in Francestown
and a new infestation of fanwort at Lake Massabesic in Auburn. Another
invasive water plant called hydrilla is lurking near our borders in Massachusetts
and Maine, just waiting to hitch a ride in.
When you do head out for the water this year, don't be surprised if you
are greeted at the boat launch by a local "Lake Host" -- a person
on duty to check your boat, motor, trailer and gear for nuisance invasive
plants before you launch. At more than 50 New Hampshire lakes, people
are stationed at boat launches to provide a courtesy inspection and educate
boaters on how to prevent the spread of exotic species. They are on the
watch for the spread of variable milfoil and other invasive plants and
animals.
The Lake Host Program is working well, according to
Connor. Last year, the program prevented exotic aquatic plants from infesting
seven new lakes in New Hampshire, including Newfound Lake, the state's
last remaining large lake still free of exotic aquatic plants. Already
this year, the hosts prevented milfoil from being introduced into Silver
Lake in Madison.
"There's no question that milfoil is one of the greatest threats
to the quality of New Hampshire's lakes, ponds, and waterways. Fiscal
health of the state and individual towns are also affected as recent studies
have shown substantial drops in shoreline property values where a waterbody
is infested with exotic aquatic plants," said Connor. "When
boaters get to a launch site, we want checking their boats, motors and
trailers for milfoil to be as automatic as making sure the boat plug is
in before they launch."
Here's how you can help to prevent the spread
of exotic weeds and other pests:
- Look for "Warning Signs" for exotic species
near boat launch sites.
- Hand-remove all materials (plant or animal) from
equipment. Don't throw the material back into the water! Dispose of
it far away from the water. Pay special attention to the bunks or rollers
where the boat is seated on the trailer.
- Wash and dry all equipment before reuse. Hose off
the boat, diving gear or trailer.
- Drain and flush the engine cooling system and live
wells of your boat, your bait buckets and the buoyancy control device
from diving equipment that's been in contact with an infested waterbody
(to protect against the spread of zebra mussels).
- Help spread the word - STOP AQUATIC HITCHHIKERS.
