Caladenia dienema

• Develop and implement a stock management plan for roadside verges and travelling stock routes.

Fire

• Implement the Arthur-Pieman Conservation Area: Fire Management Plan (Parks and Wildlife Service, 2003).
• Identify appropriate intensity and interval of fire to promote seed germination and/or vegetation regeneration.
• Where appropriate provide maps of known occurrences to local and state Rural Fire Services and seek inclusion of mitigative measures in bush fire risk management plan(s), risk register and/or operation maps.

Conservation Information

• Raise awareness of the Windswept Spider-orchid within the local community.
• Frequently engage with private landholders and land managers responsible for the land on which populations occur and encourage these key stakeholders to contribute to the implementation of conservation management actions.

Enable Recovery of Additional Sites and/or Populations

• Collect and store seed, germ plasm and mychorrizae, ensuring appropriate phytohygiene protocols are observed.
• Investigate options for linking, enhancing or establishing additional populations.
• Implement national translocation protocols (Vallee et al. 2004) if establishing additional populations is considered necessary and feasible.

• Control access routes to suitably constrain public access to known sites on public land.
• Suitably control and manage access on private land and other land tenure.
• Undertake survey work in suitable habitat and potential habitat to locate any additional populations/occurrences/remnants.
• Minimise adverse impacts from land use at known sites.
• Manage any disruptions to water flows.
• Protect populations of the listed species through the development of conservation agreements and/or covenants.

Trampling, Browsing or Grazing

• If livestock grazing occurs in the area, ensure land owners/managers use an appropriate management regime and density that does not detrimentally affect this species, outside the growing season.
• Where appropriate, manage total grazing pressure at important/significant sites through exclusion fencing or other barriers.

Fire

• Implement an appropriate fire management regime for local populations.

This list does not necessarily encompass all actions that may be of benefit to the Windswept Spider-orchid, but highlights those that are considered to be of highest priority at the time of preparing the Conservation Advice.

Research Priorities
Research priorities that would inform future regional and local priority actions include:

• Design and implement a monitoring program or, if appropriate, support and enhance existing programmes.
• More precisely assess population size, distribution, ecological requirements and the relative impacts of threatening processes.
• Undertake survey work in suitable habitat and potential habitat to locate any additional populations/occurrences/remnants.
• Undertake seed germination and/or vegetative propagation trials to determine the requirements for successful establishment, including mycorrhizal association trials.
• Undertake genetic analyses to:

1. assess current gene flow (using markers and analyses capable of distinguishing population divergence on an evolutionary timescale, from that which might be due to more recent impacts); and 
2. identify populations with low genetic diversity that might benefit from artificial introduction of genetic material from other populations from which they have relatively recently diverged.
