Abstract
This Handbook has been developed to foster the use and further development of decision support systems for prioritising weed species for management at the regional, state/territory and national levels. It is based on current best practice in weed management science, in combination with the principles of AS/NZS 4360:2004, Risk management; and HB 203:2006, Environmental risk management - Principles and process.
Scope
This Protocol provides a generic guide to the development of a post-border WRM decision framework, including the key criteria that should be considered in assessing and comparing:
weed risks posed by different plant species; and
the feasibility of managing these species through coordinated control programs.
Application
This Protocol relates to decision support systems for determining:
species for inclusion in (or removal from) noxious weed lists;
priorities for eradication or containment programs;
priorities for prevention of and early intervention against new weed incursions;
plant species with existing or potential commercial uses (e.g., for horticulture, agriculture, forestry, landscaping/gardening, revegetation or landscape remediation) which pose a weed risk and require active management to limit their spread from plantings; and
priorities for investment into research and extension leading to improved weed management (e.g., biocontrol priorities).
