11 Survey and Monitoring

The distribution of G. obtusiflora is described in Section 5 of this plan. Survey has confirmed existing records and ascertained approximate population sizes, and potential habitat adjacent to known sites has also been surveyed. No further sites have been located. However, it is likely that further sites of G. obtusiflora subsp. obtusiflora and subsp. fecunda exist.

A program of monitoring that maintains records of populations will provide the data on which the recovery of the species can be assessed, and assist in identifying the operation of threatening processes.

11.1 Objectives

To obtain further data on the distribution of G. obtusiflora subsp. obtusiflora and subsp. fecunda, and to compile population parameter data to guide future recovery efforts.

11.2 Recovery Actions

  • The NPWS will formulate and implement a program to identify areas of potential habitat of G. obtusiflora subsp. obtusiflora and subsp. fecunda and undertake survey of the identified potential habitat. The NPWS will encourage the participation of the local community and educational institutions in this program.
  • The NPWS will formulate and implement a program to monitor the condition of G. obtusiflora subsp. obtusiflora and subsp. fecunda populations, and maintain records of factors that are acting as threatening processes. The monitoring data will be used to review management actions as more knowledge is gathered. Monitoring will assess;
    • Seedling/ramet recruitment and survival,
    • age to reach reproductive maturity, and
    • the effects of any disturbance events.

11.3 Performance Criteria

  • Fifty percent of the identified potential habitat of G. obtusiflora subsp. obtusiflora and subsp. fecunda has undergone survey within five years.
  • Recovery actions are reviewed on the basis of the data collected during the monitoring program at five years.
