Invasive Species in the Columbia
Shuswap Region

By: Robyn Hooper, Program Manager, Columbia Shuswap Invasive Species Society   


What are invasive Species and their impacts?

Invasive species are defined by the Invasive Species Council of British Columbia as: plants, animals or other organisms that are not native to BC. They threaten the province’s biodiversity by overwhelming native species, damaging habitat, disrupting food sources and introducing parasites and disease. Invasive species also affect the economy by reducing grazing land and crop yields as well as limiting access to recreational areas. There are significant costs to government and private landowners to repair damage done by invasive species. Most invasive species are unintentionally introduced by human activities. That’s why each of us has a part to play in preventing and controlling their spread.

About the Columbia Shuswap Invasive Species Society

The main goal of CSISS is to prevent the introduction of new invasive species and protect ecologically sensitive areas and agricultural land from weeds and invasive species that are already present.

CSISS works with various agencies, non-profits and individuals to prevent and manage the spread of invasive species in the Columbia-Shuswap region. To achieve this, the CSISS provides education to raise public awareness of the impacts of invasive species and assist in the coordination and control efforts of agencies and individuals. The CSISS also serves as a resource in order to provide management guidance to residents of the Columbia-Shuswap.

CSISS partners with the Ministry of Forests, Lands and Natural Resource Operations to monitor biological control agents that help control noxious weeds and invasive species. Biological Control makes use of a weed’s natural enemies such as insects from its home range, to reduce plant populations. Bio-control agents are carefully screened and monitored for several years before being brought to Canada. Only some noxious weeds and invasive plants have biological control agents available for release.

Noxious Weeds and the BC Weed Control Act

The CSISS in partnership with the CSRD operates a noxious weed program based on the BC Weed Control Act. This piece of provincial legislation requires land owners or occupiers to control noxious weeds on their properties. If necessary, enforcement action may be used by the CSRD if satisfactory control is not achieved.

How can you help?

  • Know your weeds: learn to identify invasive plants and educate others.
  • Early detection is key! Report weeds to CSISS or the Report-A-Weed App through the Ministry of Forest, Lands, and Natural Resource Operations
  • Prevent weeds from establishing: Pull weeds, Clip & Bag, and Landfill disposal, Report Weeds to CSISS
  • Don’t let invasives go to seed
  • Don’t plant, buy, sell or trade invasive plants or invasive seed mixes with invasives, such as baby’s breath
  • Don’t let invasives spread from your garden
  • Stay on roads and designated trails
  • Before leaving an infested area, check yourself, vehicle or recreation equipment for invasive plant material, remove, deposit in garbage, and clean.
  • Clean, Drain and Dry boats between water bodies to prevent the spread of aquatic species
  • Plant native grasses or native wildflower mixes on disturbed sites to prevent invasive plant growth and soil erosion
