2015-01-12 General Committee Agenda Attachment 1 to Item 7 Pest Management Plan 2015-2019

There are a number of recognised lists of weeds of national interest. Twenty Weeds of
National Significance (WONS) have been identified because of their invasiveness, impacts
on primary production and the environment, potential for spread and socioeconomic impacts.
Each WONS has a strategic plan that outlines strategies and actions required to control the
weed and identifies responsibilities for each action. The National Environmental Alert List
(the Alert List) for environmental weeds identifies 28 plant species that are in the early
stages of establishment and have the potential to become a significant threat to biodiversity
if they are not managed.
