11. Alternative Management Strategies

This section considers a series of alternative options for the recovery of Bertya sp. Cobar-Coolabah and reasons for their exclusion as recovery actions in this plan.

11.1 Option 1. No Management Action Taken

As the species is possibly Bertya opponens which has a wide distribution throughout the remainder of its range in Queensland, the occurrence of the species within NSW may simply be the result of the range of the species extending into NSW. Accordingly, there may be no requirement for any 'recovery' actions for Bertya sp. Cobar-Coolabah.

This alternative approach is not considered appropriate even if the species is subsequently identified as B. opponens as the TSC Act has as a stated objective the conservation of biodiversity and the recovery of threatened species within NSW.

11.2 Option 2. Establish ex-situ Populations

The investigation of the establishment of ex-situ populations should be carried out if there is the possibility that one of the populations is suffering a dramatic decline in numbers. The ex-situ collection could involve the long-term storage of genetic material such as cuttings and seeds.

The NPWS considers that the establishment of a broad-scale ex-situ conservation program for Bertya sp. Cobar-Coolabah is not a necessary or priority action at this stage.

11.3 Option 3. Targeted Survey at Jacks Creek State Forest

While a survey for further individuals/populations in potential habitat adjacent to Jacks Creek State Forest will provide increased certainty of the total population size and distribution in this area, this action is not of high priority because the population is large (over 5 million plants) and there are currently no known threats to the viability of this population.
