- Short Term: To improve the age structure of the community by enhancing recruitment within the populations.
- Medium Term: To increase the probability of survival of Prostanthera eurybioides across the entire range of the species.
- Long Term: To improve the conservation status of P. eurybioides from Endangered to Vulnerable.
- To maintain and increase the area of occupancy of the species.
- To improve the quality of habitat of the species.
- To maintain or increase the abundance of the species.
- To preserve the degree of genetic variability within the species.
- To reduce the grazing impact of rabbits, sheep and kangaroos.
- The current known area of occupancy is increased over five years.
- The total number of mature plants is increased from its current level of approximately 2230 to 4500 in five years by planting from seed stock and increasing recruitment.
- Weed control measures substantially reduce the abundance of Avena spp., Ehrharta calycina, Lycium ferocissimum and Vulpia spp. in areas of habitat currently occupied by Prostanthera eurybioides, within five years.
- A 250m buffer is established around habitat currently occupied by P. eurybioides, where Asparagus asparagoides is to be substantially reduced in abundance within five years.
- Rabbits within the habitat critical to the survival of P. eurybioides are controlled by baiting and ripping, with a 100% reduction in the number of warrens present within five years.
- The possibility of including additional habitat containing P. eurybioides in the National Reserve System (NRS) is investigated within five years.
- Where appropriate, fencing is erected within two years to exclude sheep from populations on private property in the Monarto area.
- The impacts of kangaroo grazing and numbers in the area are investigated, with a control program, including fencing or caging where appropriate, implemented within two years if considered necessary.
- Roadside markers are installed at the site of roadside populations of P. eurybioides, and roadside maintenance staff is alerted to the presence and significance of the plants within two years.
- hrough the development of community awareness, and fencing where appropriate, the impacts of trail bike damage and illegal collecting and / or illegal rubbish dumping are significantly reduced within five years.
- Seed from each regional location is collected and stored within one year to boost current seed stores and provide seed to conduct seed longevity tests.
- Seed germination tests and seedbank trials are conducted within three years, to establish the longevity of seed maintained in storage and the extent and viability of the seedbank.
- Continue seed collection and storage to minimise loss of genetic variability.
- Undertake weed control.
- Undertake rabbit control.
- Investigate kangaroo grazing damage.
- Fence to control stock.
- Prevent damage from recreational activities.
- Install roadside markers.
- Search for new populations.
- Undertake strategic research and trials.
- Investigate the possibility of additional legal protection for P. eurybioides habitat within the National Reserve System.
- Continue monitoring of all known sites.
- Manage the recovery program through the recovery team.
- Undertake ongoing educational programs.
- Enhance recruitment.
