Can Take Over Large Portions of the Waterbody

This map was created to show how much of the lake is “littoral,” capable of supporting invasive aquatic plants.

• Destruction  of  fish habitat

• Contribute to water quality decline

• Severely impact biodiversity

• A primary cause of freshwater species extinctions

Destructive Impacts on Aquatic Ecosystems

Page 22: WHAT YOU SHOULD KNOW ABOUT - Lake Stewards of Maine … · Potential Health Impacts. Access Issues: Should Infested Water ... All it takes is a tiny fragment or seed! Wildlife Vectors

Studies have repeatedly shown that invasive plant infestations negatively impact economic activity 

associated with lakes and ponds

Depress Tourism & Recreational Activity

640,000 Maine residents recreate on  Maine lakes every year

Page 24: WHAT YOU SHOULD KNOW ABOUT - Lake Stewards of Maine … · Potential Health Impacts. Access Issues: Should Infested Water ... All it takes is a tiny fragment or seed! Wildlife Vectors

Visitors to Maine lakes spend $2.3 billion annually, generating and sustaining:

• $3.5 billion total economic activity in Maine

• $1.8 billion in annual income for Maine residents

• 50,000 jobs

Meet Dick Butterfield

The Importance of Early Detection !

Page 38: WHAT YOU SHOULD KNOW ABOUT - Lake Stewards of Maine … · Potential Health Impacts. Access Issues: Should Infested Water ... All it takes is a tiny fragment or seed! Wildlife Vectors

This is what Dick saw . . .

Page 39: WHAT YOU SHOULD KNOW ABOUT - Lake Stewards of Maine … · Potential Health Impacts. Access Issues: Should Infested Water ... All it takes is a tiny fragment or seed! Wildlife Vectors

Looking below the native plants on the surface, this is what Dick found . . . hydrilla, one of the worlds most notorious aquatic invaders.

Page 40: WHAT YOU SHOULD KNOW ABOUT - Lake Stewards of Maine … · Potential Health Impacts. Access Issues: Should Infested Water ... All it takes is a tiny fragment or seed! Wildlife Vectors

Dick’s find set off a coordinated rapid response

Subsequent invasive plants screening surveys on Damariscotta Lake revealed that Dick’s find was the 

“pioneer” population.

Lesson #1

Early detection saves lakes & lake communities from ecological and economic disaster!

Page 42: WHAT YOU SHOULD KNOW ABOUT - Lake Stewards of Maine … · Potential Health Impacts. Access Issues: Should Infested Water ... All it takes is a tiny fragment or seed! Wildlife Vectors

Lesson #2Invasive plants are not always where we expect 

them.  The more comprehensive our 

surveys, the better our chances for early 

detection.

The small lagoon where Dick found the hydrilla is remote from any public boat landing.

Page 43: WHAT YOU SHOULD KNOW ABOUT - Lake Stewards of Maine … · Potential Health Impacts. Access Issues: Should Infested Water ... All it takes is a tiny fragment or seed! Wildlife Vectors

We are making a difference!!

VLMP has trained thousands of Invasive 

Plant Patrollers across the State of Maine

Page 45: WHAT YOU SHOULD KNOW ABOUT - Lake Stewards of Maine … · Potential Health Impacts. Access Issues: Should Infested Water ... All it takes is a tiny fragment or seed! Wildlife Vectors

But our work is clearly not done . . .

THE CHALLENGE

Maine is home to 6000 lakes and ponds &             Thousands of miles of stream habitat
