- Non-native species are species of plants, animals and microorganisms that have been introduced, often by human action, outside their natural range.
- Invasive species are non-native species whose presence causes economic, ecological and/or social harm.
Non-native species can come from distant or nearby areas or countries and can be introduced into a region either by accident (e.g., hitchhikers on recreational vehicles, brought in through contaminated cargo shipments, etc.) or be the result of planned introductions (e.g., agricultural diversification, game stocking programs, ornamental plants, biological control agents, etc.).
The majority of species introduced to a region do not establish self-sustaining populations, and of those that do, only a fraction cause damage. Several non-native species are beneficial components of Saskatchewan’s culture and economy, including agriculturally important crops, domestic animals, biocontrol agents, and introduced game bird and game fish species. However, a growing number of cases demonstrate that non-native species can cause ecological, economic and social harm.
Reporting and Tracking Invasive Species
To reduce the introduction and spread of invasive species, it is important to monitor and track them. With support from the Government of Saskatchewan, the Saskatchewan Conservation Data Centre administers an invasive species mapping and data management tool, iMapInvasives.
- Report sightings of invasive species by Email or online.
- Report sightings of aquatic invasive species by contacting the nearest Ministry of Environment office or call the TIP Line 1-800-667-7561.
Prohibited and regulated non-native species in Saskatchewan
Within Saskatchewan, several pieces of legislation restrict the import and transportation of potentially harmful animals, plants, and disease, including:
- The Weed Control Act
- The Pest Control Act
- Prohibited Fish Regulations
- Forest Resource Management Act
- Captive Wildlife Regulations
Current efforts to address wild boar in Saskatchewan include the Feral Wild Boar Program, which aims to control wild boar populations through targeted elimination.
Prohibited aquatic and terrestrial plants
Terrestrial and aquatic invasive plant species are regulated under the Weed Control Act.
