This species has been assigned to the Landscape species management stream under the Saving our Species (SoS) program.
Justification for allocation to this management stream
Rhodomyrtus psidioides has a widespread distribution and the key threat to this species is the landscape scale, wind dispersed pathogen, Myrtle Rust (Austropuccinia psidii).
Status in NSW:
The SoS strategy aims to secure the species in the wild for 100 years and maintain its conservation status under the BC Act
The SoS strategy aims to secure the species in the wild in NSW for 100 years, engage local communities in its conservation, and encourage the NSW community to identify with it as a flagship for threatened species conservation.

This action statement aims to ensure the security of this species in the long-term.
This action statement aims to ensure that the species is secure in the wild in NSW and that its NSW geographic range is extended or maintained.

This action statement aims to maximise the extent of occurrence and condition of the ecological community across NSW.
Species sightings and management sites across NSW
The map below displays the species’ distribution in NSW, based upon the species’ geographic range, habitat distribution or area of occupancy (to as high a resolution as available data allow, using a range of data sources).
Information about the species’ habitat and ecology is available here.
The map may also display one or more management sites where management of important populations is underway. More information is available in the tables below.
The species occurs in the following IBRA (Interim Biogeographic Regionalisation for Australia) regions in NSW:
|NSW North Coast
|South Eastern Queensland
Proportion of the species' distribution on reserve
4% of the species' distribution occurs on reserve (within NSW National Parks and Wildlife Service estate).
Critical actions for this species
The key threats to the viability of landscape-managed species are loss, fragmentation and degradation of habitat, and widespread pervasive factors such as impacts of climate change and disease. Many of these threats are addressed by NSW planning, native vegetation, and biodiversity legislation, policy and programs including the offsets program (BioBanking, NSW Biodiversity Offsets Policy for Major Projects), Biodiversity Certification, management of environmental water and reservation under the National Parks and Wildlife Act 1974.
Threats to this species are outlined here.
The actions listed in the action toolbox are supplementary to NSW legislation, policy and programs and can be used by stakeholders, where applicable to guide management at a site, regional or state scale.
|Undertake a desktop review of species records and historical survey data and engage with consultants, NGO's and volunteer ‘spotters’ to identify rapid survey sites.|| State
|Establish record keeping systems to document provenance for each plant.|| State
|Propagate cuttings collected during field surveys in a controlled, disease free environment.|| State
|Develop partnerships with botanic gardens/nursery (target low humidity/ myrtle rust free areas) to create an ‘orcharding’ and seed production program to grow and manage plants obtained from cuttings.|| Site
|If possible, undertake seed collection for seed banking purposes. Deposit collections with the Australian Botanic Gardens - Mt Annan.|| Site
|Select a series of stratified monitoring sites to monitor on-going myrtle rust incidence, severity and symptomology over time. If possible choose sites with pre-myrtle rust baseline data and sites with co-occurring myrtaceous species (see Carnegie et al. 2016 for potential site locations).|| State
|Develop a long-term management plan for the eventual management/re-establishment of wild populations for the species.|| State
|Identify weed management sites during rapid field surveys and monitor the impact of canopy gaps created by the loss of mature trees due to myrtle rust infection on weed densities.|| Site
|Control transformer weeds (particularly vine weeds and lantana) where impacting on the species. Where appropriate use a staged approach and use methods that reduce off-target damage. Schedule regular follow up work|| Site
|Develop an education and engagement strategy about the distribution and management requirements of the species. Include impact of various activities such as clearing, grazing, weeds and other threats as well as how to identify the species and myrtle rust infected plants (e.g. field days, plant identification workshops, information packages and other community engagement activities). Engage with sympathetic landholders and utilise peer-to peer learning with other landholders.|| Area, State
|Encourage landholders to minimise and manage grazing impacts on the species, including the exclusion of stock through the erection of fences and provision of off-stream water points, or through reducing stocking density.|| Site
|Support Landcare groups and other conservation networks to continue revegetation and restoration programs to support the conservation of the species.|| Area
|Encourage landholders to consider voluntary private land conservation agreements.|| Site
|Clearing of native vegetation reduces for the area of occupancy of Myrtaceae host species, this may have consequences for genetic diversity and their resilience to infection. Liaise with Forestry Corporation of NSW to ensure habitat is protected and forestry operation impacts are minimised.|| State
|Plants can be more susceptible to Myrtle Rust infection after fire as the disease infects seedlings, fast growing shoots, leaves, buds, and fruits of the plants. Liaise with NSW Rural Fire Service to ensure habitat is protected and fire impacts are minimised.|| State
|Complete rapid field surveys across the entire species range to determine rust impact, identify rust resistant populations, sites or individuals. Use standardised protocols for recording myrtle rust incidence, severity and demographic impacts.|| State
|Undertake genetically representative germplasm collections. Collect genetic material (min. 6 individuals) from every germplasm collection site for genetic analysis of population structure and genetic representativeness of collections.|| Site, State
