Eradication Eradicate from the Shire newly established invasive species with a restricted distribution and low abundance. Containment Prevent the further increase in distribution and abundance of invasive species already present throughout the Shire. Management Invasive species are identified and actively managed within and adjacent to high value assets, but are not actively controlled outside these areas. Figure 1: The biosecurity approach (adapted from DELWP publications) A fuller description of the invasive species management categories and the actions relating to them is provided in Appendix 2. Priorities for species management Management priority is on the threat of the invasive species (high or low) against the feasibility of controlling the threat (easy or hard). High priority invasive species are species which must be removed, medium priority invasive species are species that should be removed, and low priority invasive species are species that could be removed. Invasive species management priorities can be decided using this approach: Table 1: Determining invasive species management priorities Invasive species threat Invasive species threat Threat Threat Low High Feasibility of control Hard Low Priority Medium Priority (4th) (2nd) Easy Medium Priority High Priority (3rd) (1st) Scale of management The threat potential of all species can also be considered at different scales including at the level of an individual property, a particular wetland or bushland reserve, or a Landcare area. For example, while pine trees and cherry plums are classified as an established invasive species across the Shire only to be managed to protect high value assets, if one of them were to appear on an individual property as a new and emerging weed, the owner would treat that pine tree or the cherry plum as an invasive species to be eradicated immediately. Consequently the management plans for individual properties and reserves will reflect the biosecurity approach at
