1. Aquatic Invasive Species in the Upper Great Plains Part I: Introduction to AIS

2. Aquatic Invasive Species Aquatic invasive species (AIS) Adapted to habitats regularly or permanently inundated (lakes, rivers, wetlands) Non-native species that spread rapidly, outcompete native species, and cause harm (ecological, economic, or social)

3.  Not all non-native species are invasive  Not all invasive species can establish in a given area  Often difficult to predict effects of an AIS in an area  Usually difficult or impossible to eradicate once established  Also called Aquatic Nuisance Species (ANS) in some programs AIS characteristics

4.  Recreation  Watercraft movement  Hunting and angling equipment  Live bait releases  Float planes  Consumer  Aquarium releases  Water garden escapements  Industry  Aquaculture escapements  Live food trade  Internet sales  Industrial equipment  Shipping  Natural  Inter-connected waterways  Wildlife migrations Potential pathways for AIS spread

19.  Natural spread  Downstream drift  Waterfowl  Human spread  Fragments on equipment Eurasian watermilfoil

20.  Distinguished from native pondweeds  Lasagna noodle-shaped leaves  Fine serrations on leaf margins  Typically found in 3 to 6 feet of water Curlyleaf pondweed

21.  Quickly forms dense mats on or near surface  Shades out native aquatic plants  Impedes recreation  Mid-summer die-offs can trigger fish kills Curlyleaf pondweed

23.  Natural spread  Downstream drift  Waterfowl  Human spread  Fragments on equipment Curlyleaf pondweed

24.  Viral infection that can cause many symptoms and lead to death  Hemorrhaging in eyes, skin, gills, base of fins, internal organs  Darkening of skin  Bulging eyes  Bloated abdomens  Lethargy  Pale gills  Loss of osmotic function Viral hemorrhagic septicemia (VHS)

25.  Can impact a variety of freshwater species  Many more species can act as carriers  Has led to large fish kills in isolated areas VHS impacts

27.  Natural  Downstream drift of water  Swimming of infected fish  Human  Transferring infected fish (stocking or bait)  Contaminated gear  Contaminated water VHS pathways of spread

28.  Message varies but steps are similar:  Clean – inspect equipment and remove plants, animals, and mud before leaving water access site  Drain – remove all water before leaving water access site  Dry – allow to dry completely or disinfect using approved method (hot water, bleach, vinegar, salt, freezing, etc.)  Don’t dump bait – dispose of unused bait in trash or on land  Don’t release pets and plants into the wild  Goal is to prevent movement of water and organisms Preventing the spread

31. Aquatic Invasive Species in the Upper Great Plains Part II: Program implementation and considerations

32.  Factors affecting AIS distribution  Environmental tolerances  Movement constraints  Ecosystem connectivity  Do not adhere to social boundaries  Many watersheds are shared by multiple jurisdictions  Red River  James River  Rainy Lake AIS management

34.  Recreational boaters are becoming increasingly mobile  Fishing is “big business” for all 4 jurisdictions  Anglers seek a wide variety of opportunities  Closed fishing seasons in one jurisdiction may drive interstate travel  Internet forums allow for anglers to chase “a hot bite” AIS management

35.  2012 inspection results  Boaters travel from many places to fish in Manitoba

36.  Constituent “Buy-in”  Similar regulations in the region would cause less confusion for user groups  Similar messaging in the region would prevent “mixed- messages” from agencies working towards the same goals  Clean, Drain, Dry  Inspect, Remove, Drain  Clean, Drain, Dispose  Clean, Drain, Dry, Dispose Collaborative AIS management
