In January 2003; high intensity bushfire impacted the location of subpopulation one.
Only 35 plants were recorded in subsequent surveys in February 2004 suggesting the species may be susceptible to fire related threats; but is able to withstand occasional high intensity bushfire (Frawley 2010).
Fire during the active Consequence moderate growth period could damage or destroy plants; Trend increasing and or reduce flowering and recruitment.
Due to the limited range (two sites); high frequency bushfires could potentially reduce populations of the species from fire related threats.
Additionally; fire can also impact on orchid pollinators by direct mortality or indirectly through changing plant communities and limiting food resources (Marquart 2017).
