Priority sites for protection of environmental assets
A triage approach to managing lantana to conserve biodiversity has been adopted by assessing and prioritising assets and sites for control. This process allows for management to be directed towards high priority sites that contain the highest priority environmental assets.
Ranked assets were combined with a site assessment into a matrix to provide nine categories for control (see draft Plan for full description of this process). A group of 'high priority control sites' were then selected if they fell within control category 1 or 2. Although control of lantana at any of the identified 325 high priority control sites is likely to result in recovery of high priority assets and the abatement of the lantana threat, the high priority control sites were further sorted by the variety of the high priority assets present at a site.
This within-group ranking took into account the high priority assets found at higher ranked sites and aimed to ensure that the greatest number of assets is conserved through the minimum number of sites. This is achieved by ranking sites on the basis of the greatest number of new (or unique) high priority assets present at the site. This was done so that the highest ranked sites contained the greatest variety of high priority assets. 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.
List of sites considered in the Plan
These sites occur within the core infestation of lantana, mainly coastal and eastern escarpment areas from Narooma to Far North Queensland.
New site nominations can also be made at any stage to determine additional priority sites for control. If you would like to nominate an additional site please contact us.
Maintaining areas that are presently free of lantana or removing isolated infestations, including those within other states, will also be beneficial as biodiversity in these areas will be protected from lantana invasions.
