7 Previous Actions Undertaken
NSW National Parks and Wildlife Service is unaware of any previous actions to conserve or manage the species. The lack of action by any party is most probably result of the general belief that the species is extremely rare if not extinct within NSW. However, this attitude is self perpetuating as a lack of action will do little to improve our knowledge of the species which further promotes the belief the species is rare or extinct in NSW.
The Action Plan for Australian Birds (Garnett 1992; Garnett & Crowley 2000) reviewed existing information on the Thick-billed Grasswren and proposed a four-part recovery program for the eastern form (A .t. modestus). This program included a survey to establish the subspecies present distribution, a detailed study of its ecological requirements and the impacts of grazing, development of management guidelines and an education program.
The species ability to recover in the state is considered low given the lack of any confirmed records of the Thick-billed Grasswren in NSW for almost half a century. The species decline appears to be attributed to a combination of factors relative to a broad scale change in vegetation structure that continues today. Should a population be found, active management would most likely be necessary to guarantee the population's continued viability. If no further record of the species in NSW is found before 2007 the Thick-billed Grasswren will have met the criteria under the TSC Act for nomination as 'Presumed Extinct'.
The primary objective of this Recovery Plan is to identify and conserve any extant populations of Thick-billed Grasswren in NSW.
Specific objectives of the Thick-billed Grasswren Recovery Plan are:
- targeted surveys to determine the species conservation status in NSW are undertaken in areas most likely to maintain extant populations;
- establish a community awareness and survey program;
- monitoring the results of future fauna surveys in NSW for records of the Thick-billed Grasswren; and
- develop a 'Poorly Known Status and Distribution Register' in NSW which lists Thick-billed Grasswren as well as other appropriate species in order to increase awareness and increase the likelihood of a record of the species being gained by interest groups or researchers.
Recovery criteria for the Thick-billed Grasswren are that:
- the current status of the species in NSW is determined;
- community awareness of the species and knowledge of its present status is increased; and
- efforts are made to increase the likelihood of a record of the species in NSW being obtained from any source during the life of the Recovery Plan.
