13 Research and Monitoring

13.1 Objective

  • To ensure the management of P. gibbosa habitat is adaptive to the outcomes of research and monitoring and is informed by essential aspects of the biology and ecology of the species.

Key attributes of P. gibbosa are currently unknown (see section 8.1), particularly the responses of P. gibbosa to fire and knowledge of its recruitment processes. Research into these areas combined with low-impact in-situ monitoring is required to systematically collect and analyse biological information concerning P. gibbosa and its habitat. This information will be used by land managers to make confident and informed decisions regarding the management of P. gibbosa.

13.2 Performance criteria

The criterion for the successful implementation of the research and monitoring objective is that:

  • a greater understanding of P. gibbosa is achieved and applied to the management of the species.

13.3 Recovery Actions

  1. The NPWS in conjunction with the ANOS will develop pro-formas for monitoring populations at all known sites.
  2. The NPWS will liaise with landholders to continue to undertake annual monitoring of known populations as part of the agreed management plans (TransGrid, Shellharbour Council).
  3. The NPWS will continue research into population dynamics of P. gibbosa including monitoring permanent quadrats for survivorship, flowering, capsule and seed production, in addition to conducting seed viability and germination trials.
  4. The University of Wollongong, with the permission of TransGrid and in co-operation with the NPWS will monitor the results of the ecological burn at the TransGrid site to investigate the response of P. gibbosa rosettes to fire and observe their response. The species' response to unplanned fires at Croom Rd, Albion Park will also be monitored by NPWS with permission from Shellharbour Council.
