There are other infested water bodies close by in Oxford and Cumberland Counties (ME) and in several NH & MA water bodies.

(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 - also occur in NH & MA within a 1-2 hour car trip from York County.


     Prevention and education, early detection and rapid response are all important elements of an effort to manage the

threat that these invasive aquatic species present to our waterbodies.
