Part B: Planning Components (continued)

Monitoring, Reporting and Reviewing

Data on the following information will be collected: population size and fluctuations, herbivory rate, natural pollination rate, herbivore control rate, success of hand pollination, weed invasion, effects of disturbance (e.g. track maintenance) and volunteer participation. The Recovery Team will evaluate the information biennially, and progress will be reported to the Biodiversity Conservation Programs section of the Department for Environment and Heritage (DEH), Southern Flinders District of NPWSA, TPAG, Threatened Species Network and NOSSA. The biennial Recovery Team meetings will also provide the forum for on-going review of the Recovery Plan.

Management Prescriptions for the EPBC Act (1999)

Spider orchids such as A. woolcockiorum are considered to be indicator species, because of their need for intact habitat. Consequently, all known subpopulations and areas of critical habitat should be left undisturbed or at best subjected to minimal disturbance in accordance with the following guidelines.

Tools to assist implementation

Community Participation

Due to the difficulty of access to known A. woolcockiorum sites, participation by community groups will be minimal. However, members of NOSSA and TPAG with expertise in hand pollination and monitoring will be encouraged to take part in the recovery. Also, Members of Friends of MRNP will be encouraged to assist in weed and herbivore control where necessary.


The Recovery Team will continue to serve as a means for communication between Team members. Additionally the Project Officer will deliver presentations to such groups as NOSSA and Friends of MRNP and the Regional Ecologist (NPWSA) will deliver presentations to local NPWSA staff. Track maintenance crews and fire prevention crews will be contacted directly. Articles will be compiled for local newspapers, the Parks and Wildlife journal, the NOSSA journal and the Threatened Species newsletter. These presentations and articles will cover such topics as the issues and problems related to recovery of A. woolcockiorum, the results of monitoring and the progress of recovery.

The Aboriginal Partnerships Section of DEH will undertake consultation with relevant indigenous communities. Following consultation with indigenous communities, their role and interests will be addressed in recovery plan implementation.
