Non-Plant Invasives - Columbia Shuswap Invasive Species Society

Non-Plant Invasives are shellfish, fish, insects, mammals, amphibians and reptiles and diseases that have become established beyond their natural range in a new area where they can cause negative impacts to native ecosystems. Often they have been transported intentionally or accidentally, dispersed independently and migrated due to climate change.

Regional Non-Plant Watchlist:

The presence/absence watchlist for non-plant invasive species (vertebrates, invertebrates, fungi, and pathogens) is useful for education, outreach and prevention work, including reporting; however, the watchlist is not a thorough risk assessment meant for active control programs. Land managers are encouraged to discuss control of non-plant species with Provincial specialists. Please see here for a link to the regional non-plant species watchlist: Columbia Shuswap Regional Invasive Non-Plant Species Watchlist April 2026 (Excerpt from Columbia Shuswap Operational Plan: Invasive Species 2026-2031 (Last updated 2026)).
