État de la populationTexte officiel évaluation IUCNExpert
There are likely to be approximately 100,000 known plants across the three subpopulations. Given the species can reproduce clonally (Phillips pers. comm. 3 June 2021), the number of distinct individuals (effective population size) is likely to be substantially less than 100,000, possibly around 20 per cent of the apparent number of plants (Chung et al. 2004).

Description complète des menacesTexte détaillé évaluation IUCNExpert
The main threats to the Duck’s-head Wasp-orchid currently are invasive pests, habitat degradation and climate change.

Conservation and management priorities
Habitat loss disturbance and modifications
Invasive species (including threats from grazing, trampling, predation)
Habitat loss disturbance and modifications
- Ensure locations of populations are kept updated on state databases used by fire, road and land management agencies. Where appropriate, implement measures to reduce the risk of disturbance from trail management and maintenance works.
- Implement measures to reduce trampling and impacts from recreational activities where appropriate, such as fencing and signage.
- Determine potential habitat for the species in the NSW forestry estate. Forestry: undertake pre-harvest surveys in areas of suitable habitat that are designated for harvesting and implement 100 m buffer exclusion zones from any forestry activity around all subpopulations.
- Develop a fire management plan to ensure that fire regimes occurring at the sites are consistent with population persistence of the species.
- Ensure fire management authorities are supplied with updated maps of species occurrence and that fire suppression and mop up operations avoid known populations.
- Avoid out of season planned fires from November to March.
- Avoid small fires that may concentrate post-fire herbivory on subpopulations.
- Identify and protect current and future habitat likely to remain or become suitable habitat due to climate change.
Invasive species (including threats from grazing, trampling, predation)
- Continue ongoing feral pig control near all subpopulations.
- If necessary, protect subpopulations from browsing by feral pigs (e.g. by fencing).
- Collect and maintain seed seed collections and fungal symbionts for ex situ seed banking, as per the Plant Germplasm Conservation Guidelines (Martyn Yenson et al. 2021).
- Undertake ex situ propagation and, where appropriate, translocation trials in accordance with the Guidelines for the Translocation of Threatened Plants in Australia (Commander et al. 2018). However, due to the large area of apparently suitable habitat, further surveys remain the priority for this species.
- Where translocation is undertaken, monitor all translocated individuals to maturity, seed set and recruitment to ensure they are viable and are contributing to a reduction in the extinction risk for the species.
- Engage and involve Traditional Owners in conservation actions, including surveying for new populations and management actions.
- Liaise with the local community and government agencies to ensure that up-to-date population data and scientific knowledge inform the implementation of conservation actions for this species.
- Engage community groups by encouraging participation in surveys or monitoring for the species.
- Inform managers of sites where there are known populations and consult with these groups regarding options for conservation management and protection of the species.
- Conduct targeted surveys throughout the range of the Duck’s-head Wasp-orchid to better determine its population size. Surveys should be undertaken when the species is flowering from December to March.
- Improve understanding of the pollinator, its life cycle and ecology (and that of its prey species), and its response to fire seasonality, frequency and severity.
- Improve understanding of the orchid's life history, including tuber dynamics, leaf dynamics and seedling recruitment including the microbial symbionts involved in germination.
- Improve understanding of the sensitivities of the Duck’s-head Wasp-orchid to fire seasonality, frequency and severity.
- Maintain a monitoring programme to: record response to future bushfires; determine trends in population size and distribution; determine threats and their impacts; and monitor the effectiveness of management actions and the need to adapt them if necessary.
- Increase survey effort to locate additional subpopulations.
- Investigate the population genetics of known subpopulations, particularly the number of genetically distinct individuals in subpopulations expected to contain a large proportion of clones.
- Identify the time of year plants are dormant, and the timing of leaf emergence.
- Investigate the biology and ecological requirements of the pollinator.
- Investigate recruitment, seedling survival and plant longevity/generation length.
- Identify fire regimes that are detrimental and those that allow population persistence.
