Invasive Species Monitoring

Invasive species are those species (plants, invertebrates, fish, wildlife) that adversely affect the habitats and bioregions they invade economically, environmentally, and/or ecologically. A few of the typical characteristics of invasive species that make them so dangerous to the environments into which they are introduced include:

  • Fast Growth;
  • Rapid Reproduction;
  • High Dispersal Ability;
  • Phenotypic Plasticity (ability to alter growth form to suit current conditions);
  • Tolerance of a wide range of environmental conditions; and
  • Ability to live off a wide range of food types 

AAE Tech Services Inc. is experienced in assessing lakes, streams and rivers for invasive species, including monitoring studies to assess distribution of invasive species. We are also experienced in assessing the impacts of invasive species on natural aquatic or terrestrial ecosystems. Furthermore, it is our job and responsibility at AAE Tech Services Inc. to report any sightings of new invasive species encounters to the appropriate government agencies.

Representative Studies:


Falcon Lake Rusty Crayfish 

Rusty Crayfish (Orconectes rusticus) is an invasive species that was discovered in Falcon Lake, MB by M. Lowdon in 2007. This was the first time a Rusty Crayfish was discovered in Manitoba waters. In 2009, Manitoba Water Stewardship initiated a monitoring program on Falcon Lake to better understand the impacts this invasive species may have on our native fish, plant and invertebrate communities.


Spiny Water Flea Monitoring

AAE conducted long-term monitoring to assess the presence or absence of the spiny water flea, an invertebrate introduced to the Lake Winnipeg Watershed. These assessments were typically done in conjunction with other environmental monitoring projects within the watershed.


Rusty Crayfish Distribution within Manitoba 

After the discovery of Rusty Crayfish in Falcon Lake, MB, Manitoba Water Stewardship initiated a presence/absense study to determine if Rusty Crayfish had been introduced to other lakes around the Province. Thirteen lakes across southern Manitoba were assessed.
