Past Grant Projects & Resources:

In June 2005 York County Soil & Water was awarded a grant through the National Fish & Wildlife Foundation. The Expanding Southern Maine Community Invasive Plant Control Phase 1 project encompassed developing an Integrated Pest Management plan (IPM), creating a steering committee, hosting workshops for ID & control of noxious weeds as well as distribution of education materials. We are also working with Noble High School to incorporate invasives in their curriculum.

The following is a review written by a student in Mr. Perks class at Noble High School after a presentation given by YCSWCD's Heather Dionne regarding Invasive Plants

            "Heather Dionne from York County Soils & Water District on Invasive Species had a really good point. What she said was the some companies and people accidentally spread invasive plants around the state, like Japanese Knotweed. What the plant would do is take over the surrounding environment because they have no competition. I agree with what she said, because that stuff happens all the time. A company will send out sand or soil for a house they’re making, and there will be an invasive plant or seeds in it, without them knowing."

Phase 2 of this grant began in the spring of 2008.
