Prevent:  Species determined to be high risk to BC and not yet established. Management objective is prevent the introduction and establishment.

Provincial EDRR: Species is high risk to B.C. and is new to the Province. Management objective is eradication.

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.
