Threatened Species Management Plan for Kinglake National Park, – V 1.0, September 2001 Corybas sp. aff. diemenicus 4 Mountain Helmet-orchid (?Threatened in KNP) Notes: observed by one of the authors (CB) as an epiphyte on tree ferns in the headwaters of the Plenty River, above Road 14. Likely occurs elsewhere in wetter forest. Corunastylis archeri Variable Midge-orchid (Threatened in Region & KNP) Notes: very rare and localised to Broad Gully (single plant in 1993). Also observed adjacent to the Park at Brennan Avenue (20-30 plants in the early 1980’s). Variable Midge-orchid is very rare throughout the region and has declined substantially (extinct at Heathmont and the Dandenong’s). Usually found in valley heathy forest, often occurring with C. morrisii and C. despectans. Corunastylis morrisii Bearded Midge-orchid (Threatened in Region & KNP) Notes: scattered and rare at Road 54, Road 15, Watsons Creek Track, lower Bundy Track and at Broad Gully. Observed flowering at Broad Gully in April 2009 two months after the bushfire. Cryptostylis leptochila Small Tongue-orchid (Threatened in Region & KNP) Notes: restricted to Broad Gully where reasonably common (prior to 2009) and several plants on the spur of Mt Sugarloaf (growing with Elbow Orchid). Also observed along Road 54 in herb-rich foothill forest. No plants were observed at either location in spring of 2009. Small Tongue-orchid is possibly impacted by high intensity fires. One plant was located on Mt Slide during field work in early 2010 in an area that had burnt at moderate intensity. The flowering bud was grazed off prior to flowering. Cryptostylis subulata Large Tongue-orchid (Threatened in Region & KNP) Notes: widespread and rare including small populations in lowland forest and valley heathy forest at Reedy Creek where observed in 2008 and 2010 and Black Calf Creek where observed in the early 1990’s (both around 10 plants). Several thousand were observed by one of the authors (CB) at Broad Gully between 1988-1993. This population declined drastically during the drought and no plants were observed following the 2009 bushfire. Cyrtostylis reniformis Small Gnat-orchid (Threatened in Region & ?KNP) Notes: recorded by Cliff Beauglehole (1983). This species is usually confined to lowland sites and the reliability of this record is uncertain. The common names ‘gnat orchid’ and ‘mosquito orchid’ have been used interchangeably in the past and the record possibly refers to Acianthus pusillus. Diuris orientis Wallflower Orchid (Threatened in KNP) Notes: scattered and rare in the southern section of the Everard Block, where observed off Watsons Creek Track and Everard Track in 2009 and 2010. Wallflower Orchid is a key fire-response species that has been observed to flower profusely following ecological burns. Lyperanthus suaveolens Brown-beaks (Threatened in Region & KNP) Notes: very rare and localised (one colony of 10 plants observed at Broad Gully between 1988 and 1993 in heathy dry forest). Also recorded by Cliff Beauglehole (1983), location unknown. Microtis arenaria Notched Onion-orchid Notes: localised and rare in lowland forest south of Reedy Creek. Likely to occur elsewhere. Pheladenia deformis Blue Fairies (Threatened in Region & KNP) Notes: very rare and localised in grassy dry forest adjacent to Dinsdale Road (3-4 plants observed by the authors in September 2007). The plants were grazed-off following a fuel reduction burn in April 2010. 48
Threatened Species Management Plan for Kinglake National Park, – V 1.0, September 2001 Management: the plants were protected with tree guards after discovery, but these were removed prior to the fuel reduction burn. These plants must be caged or fenced to prevent grazing impacts. 2011 observation: No leaves of Blue Faries could be located during mid-August. The plants have either gone dormant of have been eliminated by grazing. Prasophyllum flavum Yellow Leek-orchid (Threatened in Region & KNP) Notes: very rare and localised where observed by one of the author’s (CB) in Messmate forest at Jehosaphat Gully in the 1980’s and in wet forest along Road 14 in Mt Disappointment Reference Area. Yellow Leek-orchid is very rare in the region. The next nearest records are in the Dandenong Ranges. Prasophyllum brevilabre Short-lip Leek-orchid Notes: scattered and uncommon throughout heathy formations (Broad Gully, Road 10, Everard Track, Reedy Creek). Most populations are between 5-10 plants. Short-lip Leek-orchid is a key fireresponse species that flowered profusely throughout burnt areas of the Park in spring 2009. The Park supports the largest population of this species in the region. Prasophyllum lindleyanum Green Leek-orchid (VROT: Vulnerable; Threatened in Region & KNP) Notes: discovered by park ranger Phil O’Connor in the spring of 1981 in the eastern section of Broad Gully. The site had been subject to an ecological burn in autumn of that year. A specimen was vouchered to the Melbourne herbarium. The site was searched by one of the author’s (CB) every spring between 1987 -1993 and five times between 1993 and 2008 but no plants were observed. Limited targeted surveys were undertaken in early summer of 2009 and no plants were located. Green Leek-orchid is very rare throughout Victoria where it is found in damp heathy formations. It flowers profusely in the first and second year after fire but becomes dormant by the third year. Green Leek-orchid has possibly declined to extinction at Broad Gully due to the effects of long-term drought and grazing pressure. Prasophyllum odoratum Scented Leek-orchid (Threatened in Region & KNP) Notes: localised and rare in heathy forests at Broad Gully, Steels Creek Road - south of Full and Plenty Creek and along overview ridge on Road 15. Pterostylis atrans Dark-tip Greenhood (Threatened in Region & KNP) Notes: localised and rare along Bundy Track and Watsons Creek Track 150 metres from the Marshalls Road gate. Possibly more widespread and over-looked. Pterostylis decurva Summer Greenhood (Threatened in Region & KNP) Notes: single plant seen in late 1980’s along Road 14, 500 metres south of Road 3 in Mt Disappointment Reference Area. Also recorded immediately adjacent to the Park by one of the authors (CB) on the summit of Mt Disappointment. The plants were growing amongst granite boulders. Summer Greenhood is a wet forest species that prefers open sites. Pterostylis foliata Slender Greenhood (Threatened in Region & KNP) Notes: recorded by Cliff Beauglehole (1983) from Jehosaphat Gully. The next known population occurs at Rifle Range Reserve. Could potentially occur on the northern side of Mt Disappointment amongst granite. Pterostylis falcata Large Sickle Greenhood (Threatened in Region & KNP) Notes: localised and very rare in two western tributaries of Reedy Creek including 11 plants at one site where growing with the rare hybrid Pterostylis x ingens and another site of over one hundred 49
