New Invasive Plants Being Considered for Regulation

Did you know?  The Alberta Weed Regulatory Advisory Committee (AWRAC) is a multi-stakeholder group that makes recommendations on changes to the invasive species listed in the Alberta Weed Control Regulations.  This is a very important mechanism to keep the Weed Control Regulation up to date with new threats.  AISC is participant in and strong supporter of AWRAC.  AWRAC Link

Alberta Takes Action on Aquatic Invasives

To make sure Alberta remains mussel free, CLEAN, DRAIN & DRY your boat!!!  Exciting times in the world of Aquatic Invasive Species (AIS)! 16 seasonal staff have been hired on as boat inspectors! We’ll be training next week and then (ideally) opening the stations the week of June 9th on major highways entering Alberta. Tourism, Parks & Recreation will also have two roving crews doing boat inspections at provincial park boat launches all summer! 

With the help of the Alberta Invasive Species Council and the Eastern Irrigation District, 700 CLEAN DRAIN DRY Your Boat signs were ordered for boat launches! Thanks to this great partnership for helping out!  We are looking for popular boat launches to sign.  If you know of one and are interested in erecting a sign ............  let us know at  


Coming soon: List of waterbodies to be monitored this summer. With help from Tourism, Parks & Recreation, Agriculture & Rural Devleopment, Alberta Lake Management Society, and Alberta Environmental Monitoring, Evaluation and Reporting Agency we’ll be able to get to more than 70 waterbodies province-wide for invasive mussel monitoring!
