Today, there are more than 200 weed species known in the Illawarra.
Most are environmental weeds like Morning Glory, Maderia Vine, Lantana and Asparagus Fern. Some, like Bitou Bush, are also listed as noxious weeds, as Weeds of National Significance, or a Key Threatening Process under the NSW Threatened Species Conservation Act 1995.
Weeds threaten biodiversity due to their ability to out compete native plants. A reduction in native species can lead to a drop in the diversity of flora and impact on fauna habitat.
Weeds found in the Illawarra include a range of grasses, forbs, shrubs, trees and vines and aquatic weeds. For a list please see Weeds of the Illawarra.
Council and the community have been working together to remove weeds on public land through bush regeneration contracts and Council’s Bushcare and FireReady programs.
The Illawarra District Noxious Weeds Authority also implements an active noxious weed control program throughout the Wollongong Local Government Area.
