Review of the NSW Bitou Bush and Boneseed Threat Abatement Plan

The NSW Bitou Bush and Boneseed Threat Abatement Plan (Bitou TAP) was released in 2006. After five years of implementation, the TAP was reviewed in 2011 as per the requirement under the NSW Threatened Species Conservation Act 1995.

This review’s findings are presented in the Bitou TAP Review (130350BitouTAPR.pdf, 2.1 MB).

The review assessed implementation against the eight Bitou TAP objectives. Of these, five were achieved, one was partially achieved and two were not achieved over the last five years. Some key achievements of the Bitou TAP were:

  • bitou bush management occurred on 157 priority sites, with most sites being the highest priority (control category 1)
  • standardised site management plans were developed and implemented for 57% of high priority sites
  • mapping has revealed that the density of bitou bush was reduced in national bitou bush containment zones and the containment lines had receded
  • monitoring programs were established at 76 sites, and bitou bush abundance was reduced across priority sites, from a median cover of 26–50% in 2007 to 0–5% in 2011
  • where sufficient site monitoring data was available, results indicated an increase in the abundance of native plant species
  • key resources were developed and provided to stakeholders to increase their capacity to implement the Bitou TAP, including a best practice management manual, monitoring manual, and a field plant identification guide
  • over 120 community groups assisted site managers with on-ground control
  • the five former coastal catchment management authorities and OEH received significant Australian Government funds to implement the Bitou TAP.

Future Bitou TAP implementation

This review did not identify a need for major revision of the TAP objectives. It is recommended that implementation and resourcing of the TAP continue and that future investment in bitou bush management be guided by:

The BPWW applied the TAP approach to identify and prioritise: i) all widespread weeds impacting on native biodiversity; and ii) sites for weed control. Existing Bitou TAP sites were incorporated into the BPWW and new bitou bush sites have since been nominated.
