Objectives
• Outline Invasive Species
Problem
• What is APIPP?
• Describe Aquatic
Species
• Spread Prevention
• Brant Lake Update
• Management
• Let’s look at some plants!
What’s the Difference?
1. Native Species• Species indigenous to a region at the time of European
settlement
2. Non-native Species (Exotic, Introduced, Alien)
• Accidental or purposeful introduction of a species
outside of its historic range
3. Invasive Species (Noxious)
• Species that rapidly reproduces, displaces native species
and causes ecological, economic or societal harm
4. Nuisance Species (Weed)
• Species that interferes with human activities
♦ Provide food
♦ Provide shelter and spawning habitat
♦ Produce oxygen
♦ Protect shoreline
♦ Stabilize sediments
♦ Reduce turbidity
♦ Transport nutrients
♦ Support diversity
Benefits of Native PlantsBenefits of Native Plants
Characteristics of Invasive Plants
♦ Lack predators, parasites, and disease to limit growth
♦ Produce many small seeds and reproduce early
♦ May reproduce both by seed and vegetative growth
♦ Have few special seed germination requirements
♦ “Generalists” capable of colonizing a wide range of sites
♦ Monopolize resources such as light and nutrients
♦ May produce toxins that suppress the growth of other plants

Nonnative Fishes -
Historic Conditions
Relatively few fish species in interior waters
“Yellow perch, smallmouth and largemouth
basses, the northern pike, the chain pickerel…
…and many other species were then almost
endlessly dumped upon the Adirondack uplands.”
Impacts of non-native fishes
• Ecosystem altered by “top-down” cascading
effects.
• Predation and competition cause severe
declines in brook trout and round whitefish.
• 1890: “…are found in nearly all the salmon
and trout lakes in the Adirondacks.”
• Now: Seven waters (scarce in most) plus
some recent stockings.
Management of
non-native fishes
• Regulations
• New bait regulations
• Green list
• Restrict overland transport
• Education
• Fish barriers
• Reclamation with rotenone (fish pesticide)

APIPP Objectives
1. Prevent new invasions.Increase public awareness and involvement to
prevent the spread of invasive plant species.
2. Rapidly detect and eradicate infestations.Coordinate regional invasive plant inventory and
monitoring program utilizing staff and volunteers.
3. Manage established infestations.Facilitate the management, containment, and
control of priority invasive plant infestations.

2009Paradox Lake Milfoil Survey Plan
Avoid boating through invasive plant beds
Never release unwanted bait into a waterbody
Never move fish from one water to another without the proper permits
Clean off your boat / remove vegetation
Clean out / disinfect live wells
Check your boat before you float!
Spread Prevention Continued
Check and remove any visible mud, plants, fish, or organisms from boats, trailers, equpiment, etc.
Clean and eliminate water from equipment
Dry anything that comes in contact with water
Never release plants, fish, or other animals into a waterway unless they came from that waterway.

Action Plan
for
Milfoil Issue
Our approach
Similar to fighting weeds in regular garden:
Identify and locate
Surveying
Reports from locals
Head-A-Bed
Remove or kill
Hand harvesting and Benthic matting with
Volunteers
AIM
Results of our approach
Where are we NOW compared to where we
would be if we had taken NO ACTION…
