Because invasive plants
have not co-evolved within the specific lake ecosystem to which they have
been introduced, they are often not susceptible to competition and disease
and thus have an advantage over
native species. Once introduced, invasives can displace
native plant and animal communities, degrade a lake�s recreational value,
and can significantly reduce property values. Aquatic plants often travel
from
lake to lake via boat propellers and trailers, which
explains why outbreaks are typically found near boat ramps. Groups like the
Maine Volunteer Lake Monitoring Program and Courtesy Boat Inspection have
been very active and
successful in preventing the introduction of invasive species. Maintaining
vigilant supervision at boat ramps and creating public awareness are
important parts of the prevention process.
