AQUATIC INVASIVE SPECIES
working group
 
Overall area of project – Saskatchewan, plus potential for cooperative projects within Northern Great Plains states and provinces.
Focus: AIS including quagga/zebra mussels, snakeheads (channa argus), Asian carp, and aquatic vegetation species: salt cedar, Eurasian watermilfoil, purple loosestrife, flowering rush.
Most immediate threats appear to be invasive mussels, milfoil and loosestrife; possibly carp.
 
AIS THREATS
  • Fish habitats (sport and commercial) are threatened by most invasives.
  • Existing and increasing infrastructure requirements for municipalities and industry are threatened by some invasives (mussels).
  • Increasing numbers (and varieties) of trailerable recreational vessels increase potential for transport of aquatic invasives.
  • Climate change related events exacerbate threats: watercourse and overland flooding provide new vectors for spreading all invasives.
PWWG RESPONSE TO THREATS
  • Work closely with Watershed Stewardship organizations to develop and implement a network of volunteer AIS Monitors (underway)
  • Lead a consistent public awareness program about invasives (underway)
  • Deliver informational material and workshops for Watershed Stewardship organizations and other stakeholders. (underway)
  • Involve AIS Monitors in presence/absence monitoring plan, beginning at key lakes and rivers, using existing infrastructure (pipe docks, boat lifts, water intakes)
  • Promote via regional and provincial parks as partners
  • Lead the development (or adaptation), and support, an accessible subject-specific reporting system and database, enabling rate of expansion mapping. (underway)
  • Implement veliger sampling program
  • Equip laboratory for presence/absence monitoring (mussel veligers) and other invasive species
  • Lead the development of private-partnership network for vessel, vehicle and equipment decontamination
  • Solidify working relationships – provincial, western and near-border states
  • Establish appropriate sponsors and partners into the future
