Invasive Mammals

Invasive mammals are animals from one part of the world that are transported, or migrate due to climate change, beyond their natural range and become established in a new area where they can cause potential harm to native ecosystems.

Prevent

Species determined to be high risk to B.C. and not yet established. Management objective is prevent the introduction and establishment.

 Provincial Containment

Species is high risk with limited extent in B.C. but significant potential to spread. Management objective is to prevent further expansion into new areas with the ultimate goal of reducing the overall extent.

Regional Containment/Control

Species is high risk and well established, or medium risk with high potential for spread. Management objective is to prevent further expansion into new areas within the region through establishment of containment lines and identification of occurrences outside the line to control.

Management

Species is more widespread but may be of concern in specific situations with certain high values - e.g., conservation lands, specific agriculture crops.  Management objective is to reduce the invasive species impacts locally or regionally, where resources are available.
