INVASIVE AQUATIC PLANT SPECIES IN
YCSWCD has received funding from the
John Sage Foundation
for the 2013 season
with a special survey focus on section of the Salmon Falls River. We will also
be checking sections of the Saco, Little Ossipee & Ossipee this summer.
Join us on July15th for a paddle with the folks at Acton Wakefield Watershed
of the main goals of this project is to provide volunteers with skills & tools
to become active in invasive aquatic species spread prevention,
early detection and rapid response efforts in York County.
These three elements are important & effective strategies to minimize the
monetary & ecological impacts of an invasive aquatic species introduction or
23 water courses* infested with 6 invasive aquatic plant species.
these were described as 33 waterbodies that are now defined as water courses)
23 water courses in Maine, York County has 8 water bodies where 4 different invasive aquatic
plant species have been detected.

8 York County locations include:
Variable milfoil in 5 of the 8 infested water bodies,
Hydrilla occurs in 1, curly-leaf pondweed occurs in 2
(or European water nymph) has been found in one.
A pond in
Kittery with the European naiad is also one of the sites with curly
County water bodies have very active invasive aquatic plant management projects
that have been carried-out each year
past several years. Those are Pickerel
Pond in Limerick (hydrilla), West Pond in Parsonsfield (curly leaf
Lake in Acton & Newfield, ME and Wakefield, NH (variable milfoil) and
Arrowhead in Waterboro & Limerick (variable milfoil).
one plant of variable milfoil was found in Great East Lake & it was

Quick Key to Invasive Aquatic Plants
There are other infested water bodies close by in
Oxford and Cumberland Counties
(ME) and in several NH &
(For the MA link to the MA waterbodies,
go to page 34 of the pdf document or page 26 of the hard copy document to see a
list of infested waterbodies.). Many of the infestations are Variable leaf water-milfoil, but Eurasian
water-milfoil has also been found in a private, un-named gravel pit pond in
Scarborough, in a small pond in Brookfield, NH and also in a number of
waterbodies in northern MA. Other invasive aquatic plant species
– such as fanwort & water chestnut -
occur in NH & MA within a 1-2 hour car trip from York County.
Some water bodies are more susceptible than others to
the introduction of an invasive species. The sooner an infestation is detected
the less troublesome and costly the management will be. Great East Lake is an
of an “early
detection and rapid response” success story.
Early detection, education, prevention and rapid
response activities are all important strategies to manage the threat that these
invasive aquatic species present to our waterbodies.

Prevention and education, early detection and rapid response are all important
elements of an effort to manage the
that these invasive aquatic species present to our waterbodies.
