AQUATIC INVASIVE SPECIES AND HABS
Diane Oleson, Penn State Extension
What is an Invasive Species?• Defined by Executive Order
• Outside native range• Brought in by artificial means• Economic, ecological or human, plant
or animal health harm
• Different from a native plant that overgrows the pond
Why are Invasive Species a Problem?
• Characteristics• Come in all forms – plants, insects, animals,
pathogens – both terrestrial and aquatic• Tolerate wide range of environmental conditions• Have few diseases, parasites or predators• Produce large numbers of offspring, spread
rapidly• U.S. control / losses = $Billions annually
How do they move?• On equipment
• Bait Bucket
• Waterfowl / Wildlife
• Aquarium release
• Stocking Just seem to show up

Why are Invasive Aquatic Plants a Problem?
Aquatic Invasive PlantsCompete with native vegetation Reduce wildlife habitatReduce biodiversity
Form mats:Interfere with flood control, irrigation, navigationInterfere with recreational activities
(swimming, boating, fishing)Reduce dissolved oxygen in the water Create mosquito breeding habitat

Hydrilla, waterthyme, Hydrilla verticillata• Native to Asia or Africa• Can grow 20-40 feet deep• Spreads by fragments• Forms resistant overwintering tubers• Forms dense mats• Aquarium plant release
WatermilfoilsParrotfeather watermilfoil Myriophyllum aquaticum
• Native to South America• Water garden introduction• Forms mats
John M. Randall, The Nature Conservancy, Bugwood.org
Eurasian watermilfoilMyriophyllum spicatum
• Eurasian origin• Forms mats• Ballast water, worm packing,
aquarium plant

Submerged Invasive Plants
Chris Evans, River to River CWMA, Bugwood.org
Curly leaf pondweed, Potamogeton crispus
• Tolerates low light, low water temperatures
• Forms dense mats• Causes eutrophication => Increased algal
blooms

Water Chestnut, Trapa natans• Roots 12-15 ft deep• Floating mats of rosettes• Nasty spiny seeds• Fragments form new plants

Best Management PracticesMaintain your pond
Make sure problem plants or animals stay in pondWhen selecting plants, do your homework
Look at what you are putting in and around the pondIs it on a noxious weed list? Why?Use native plantsDon’t share what you don’t know
Don’t dispose of aquarium critters in ponds or streamsClean and inspect everything before installingObtain fish for stocking from reputable sources
In General - Most plant problems are NUTRIENT problems
Test your waterInvasives need to be eliminated, if possible
Vegetated BuffersRestrict fertilizer, manure, sediment runoffControl geeseHerbicides are a temporary fix
MUST identify the plant Obtain permits PA Fish & Boat / DEP
Nuisance Native Plants - Algae
Filamentous Algae
• Slimy, stringy• Start as mats on the bottom• Different algae at different
times
Planktonic algae
• Microscopic algae - float in the water column
• Water looks green, brown, reddish• Can sometimes be confused with
muddy water
Toxin Producing Algae = HABsProduced by some ‘Blue-green algae” = Cyanobacteria
– Closely related to bacteria, but larger– Produce a variety of toxins, 2 of particular importance– Microcystin – hepatotoxin; Anatoxin-A – neurotoxin– 3 main problem species: “Annie, Fannie and Mike”
• Anabaena, Aphanizomon and Microcystis
– Toxins - Not all the time, not for long periods – Nutrient rich conditions, warm water temperatures– Toxins released when cells die– NOT a new problem
Most Common Culprits
AnnieAnabaena
FannieAphanizomenon
MikeMicrocystis
Microcystis Common in Great Lakes Multiple HAB events, most recently in Toledo OH NOAA runs Lake Erie Bulletin This will only get worse

Health Effects and PrecautionsPets and livestock have died from ingesting toxin contaminated water, people have become ill.• People, pets and livestock should
avoid contact with water showing bloom symptoms.
• Never drink untreated surface water, whether or not algae blooms are present.
• In-home treatments do not protect people from blue-green algal toxins.
• As a precaution, rinse washed dishes with bottled water.
Stop using the water and seek medical attention if symptoms such as vomiting, nausea, diarrhea, skin, eye or throat irritation, allergic reactions or breathing difficulties occur while in contact with untreated surface waters showing signs of a bloom.
