Biological Control of Invasive Plants

Invasive plants are non-native plants that have been introduced from other continents and are thriving in Alberta.  They spread in the absence of their natural predators and pathogens.  A biocontrol agent is a Government of Canada approved insect or pathogen that is introduced to control an invasive plant.  MORE INFORMATION

Starting in 2016, the Alberta Invasive Species Council (AISC) has become actively involved in the release and monitoring of biocontrol agents for managing invasive plants.  This is a result of a collaboration between AISC and Agriculture and Agri-Food Canada (AAFC) at the Lethbridge Research Station.  This initiative is supported by Cardston County, County of Forty Mile, Cypress Country, MD of Pincher Creek, MD of Taber and the MD of Willow Creek.

AISC staff make the releases and complete the monitoring in the following season.  AISC handles all invoicing.  Records of the release site locations and monitoring results are kept in an AAFC database.  This data is used to build the understanding of the biocontrol agents and for further work by AAFC scientists.  The follow up monitoring is a critical part of the program.  

The invasive plants targetted are: Houndstongue, Dalmation Toadflax, Leafy Spurge, Diffuse knapweed and Spotted knapweed 


How the program works?

1) You contact AISC at operations@abinvasives.ca with your interest in a biocontrol release on one of the targeted invasive plant for a site you manage.

2) AISC will contact you when insects have been collected and a release is ready to be made.

3) Knowledgeable AISC staff travel to your invasive plant location and make the insect release.  The GPS coordinates of the release site are recorded and become part of the AAFC database.

4) AISC invoices you via email for the release. (the costs for 2017 releases will be announced in April, 2017)

5) You pay by cheque or credit card (on the AISC website "online payments")

6) The following year, an AISC crew visits the release site and monitors the progress of the insects.
