MILFOIL UPDATE - NOVEMBER 2007
For some three to four years our association
has been involved in making sure
no aquatic invasive species or Milfoil
gets started in Worthley Pond. Milfoil is
the most common species but there are
actually 11 different plants on the state
watch list of which only 5 have been
found in Maine. No new infestations
have been added to the state list since
2006.
You can access more information on milfoil
by going to the "Links" section of our
website (www.worthleypond.org) and
click on Maine Center for Invasive
Aquatic Plants. Here you can see the
state list of "Eleven Most Wanted" plants
we don't want and the Maine DEP Listing
of infested water bodies.
The Courtesy Boat Inspection Program
is our best tool to combat an infestation.
Second is doing Invasive Plant Patrols
around the entire shore of our pond. This
is done partially by shore owners seeing
a new and unusual plant growing in front
of their property. This has resulted in
several samples being gathered and
identified to be native milfoil that has
always been in the pond but has a lot of
the look-Alike characteristics of invasive
milfoil species. Invasive Plant Patrols are
persons who have been trained to identify invasive plants, looking along the
shore at regular intervals for any new
suspicious plant life. This is done by
boats and people snorkeling. These
plants almost always occur in 15 feet or
less as they depend on sunlight to prosper.
An active Plant patrol program recorded
big success in 2006 on Great East Lake
in Acton, Me. and Wakefield N.H. Part of
a group of "Weed Watchers" on the lake,
Carol Lafond was on patrol snorkeling
when she found a newly established single
variable milfoil plant and promptly
removed it. Now the state is preparing to
remove Great East Lake from its list of
29 documented ponds with invasive
plants since no further plants have been
found during intensive surveys this past
year. But this is not usual but very fortunate
for this lake. Early detection is the
key!!!
Remember once a water body gets
infested there is no cure to date. Much
money is being spent around the state to
try and keep it contained so it does not
spread into other parts of a lake, pond or
stream. Many cure- alls have and are
being tried but nothing to date. One such
example is in Vermont. In Fairfield Pond
weevils were added to the pond's milfoil
beds and there is some hope. The beds
are thinning as the weevils hollow out the
plants' stems. If this works it will take
time to grow enough weevils to attack
plants in other parts of New England. But
for now we must be vigilant in keeping
out these plants and patrolling for the
one that may make it through!!
Now that Worthley has a successful
Courtesy Boat Inspection Program we
now need to develop an Intensive Plant
Patrol Program to detect early any of the "11 Most Wanted Plants" that may seek
to become residents of Worthley Pond.
Next year we hope to find volunteers
who will participate in the training and
start regular patrols around the pond. All
one needs is a watercraft. Anyone who
enjoys snorkeling can do this and enjoy
their sport and do great things for
Worthley Pond. We also plan to provide
another milfoil workshop similar to one
several of us attended several years
ago. It will be refresher course plus a
chance for new volunteers to learn to
identify invasive aquatic plants. We hope
to set these up with several other area
camp associations. More about this in
the Spring!!!
