Impact
Some economic impacts are lantana infestations cost more than $104 million per year, land managers spend more than $17 million per year on lantana control and raises production costs in the commercial forestry.
Some biodiversity impacts are threatening more than 1400 native species and 100 ecosystems which includes 279 plants and 93 animals in the national threatened species legislation.
Some social impacts are increasing individual stress associated with economic loss, threatening culture heritage areas and reduced aesthetic appeal of nature areas.
Management
Accessing and prioritising assets and sites for controls This should ensure that management is directed to
sites with different assets, as opposed to managing a multiple number of sites that have the same assets
Maintaining areas that are presently free of lantana or removing isolated infestations
