This Conservation Advice was approved by the Minister / Delegate of the Minister on: 1/10/2008 Approved conservation advice (s266B of the Environment Protection and Biodiversity Conservation Act 1999) Approved Conservation Advice for carnea var. subulata (Striped Pink Fingers)

This Conservation Advice has been developed based on the best available information at the time this Conservation Advice was approved; this includes existing plans, records or management prescriptions for this species.

Description Caladenia carnea var. subulata, Family , also known as Striped Pink Fingers, is a small terrestrial orchid with a hairy, dark green, erect leaf. It grows to 25 cm tall and carries 1–4 flowers. The white to bright-pink flowers are 2–3 cm across, have an erect rear and four other spreading forwards. The labellum (lip) has dark red bars and two rows of yellow calli (non-secreting glands found on the labellum) (Jones & Jones, 2000). Striped Pink Fingers entirely lacks central calli on the flower lip and has a long, narrow acute midlobe that is not recurved (Bishop, 2000). Flowering occurs from October to November (Nicholls, 1945), while flowering in P. carneus can occur from August (Jones, 2006). Caladenia carnea and its varieties have recently been taxonomically assigned to Stegostyla gracilis and a number of species of Petalochilus. Caladenia carnea var. subulata has been included in Petalochilus carneus (Clements, 2008), although its lack of calli suggests it is an aberrant form (Bishop, 2000) and it is doubtfully worthy of taxonomic recognition (Jones, 2000). Petalochilus carneus is considered a synonym of Caladenia carnea var. subulata in the Australian Census (see CPBR, 2008).

Conservation Status Striped Pink Fingers is listed as endangered. This subspecies is eligible for listing as endangered under the Environment Protection and Biodiversity Conservation Act 1999 (Cwlth) (EPBC Act) as, prior to the commencement of the EPBC Act, it was listed as endangered under Schedule 1 of the Endangered Species Protection Act 1992 (Cwlth). The subspecies is also listed as threatened under the Flora and Fauna Guarantee Act 1988 (Victoria) and the Victorian Department of Sustainability and Environment lists Striped Pink Fingers as presumed extinct (DSE, 2005).

Distribution and Habitat Striped Pink Fingers is known from the Portland area of western Victoria. The only collection held at the National Herbarium of Victoria was collected near Portland in 1943 (Nicholls, 1945). Another collection is held at the Royal Botanic Gardens in Sydney (AVH, 2008). This variety occurs within the Glenelg–Hopkins (Victoria) Natural Resource Management Region. Striped Pink Fingers was reported as occurring plentifully in good seasons (Nicholls, 1945) but there have been no known collections or sightings of this species since the late 1940s (MEL collection records, undated). Petalochilus carneus has a much wider distribution than Striped Pink Fingers, occurring from Hervey Bay in Queensland, to NSW, ACT, Victoria and (Jones, 2006). It is considered widespread and common within its range (Jones, 2006) and often survives or recolonises areas cleared by human activity (Bernhardt, 2007). It occurs in coastal lowlands and montane areas to 800 m and inland some distance (Jones, 2006), and has been found in habitats from heath and mallee to woodland and forest (Jones, 2006). The distribution of this taxon is not known to overlap with any EPBC Act-listed threatened ecological communities.

Caladenia carnea var. subulata Conservation Advice - Page 1 of 3 This Conservation Advice was approved by the Minister / Delegate of the Minister on: 1/10/2008 Threats There are no identified threats to Striped Pink Fingers, as the Victorian Department of Sustainability lists Striped Pink Fingers as presumed extinct (DSE, 2005).

Research Priorities Research priorities that would inform future regional and local priority actions include: • Undertake survey work in suitable habitat and potential habitat to locate any additional populations/occurrences/remnants. • Clarify the taxonomic status of C. carnea var. subulata, and, if appropriate, review its threat status.

Regional and Local Priority Actions If new populations of C. carnea var. subulata are discovered, the following priority recovery and threat abatement actions can be done to support the recovery of Striped Pink Fingers. Habitat Loss, Disturbance and Modification • Identify populations of high conservation priority. • Manage threats to areas of vegetation that may contain populations of Striped Pink Fingers. • Investigate formal conservation arrangements such as the use of covenants, conservation agreements or inclusion in reserve tenure if populations are located. Conservation Information • Raise awareness of Striped Pink Fingers within the local community. Enable Recovery of Additional Sites and/or Populations • Undertake appropriate seed collection and storage if any individuals of Striped Pink Fingers are found. • Investigate options for establishing additional populations. • Implement national translocation protocols (Vallee et al., 2004) if establishing additional populations is considered necessary and feasible. This list does not necessarily encompass all actions that may be of benefit to Striped Pink Fingers, but highlights those that are considered to be of highest priority at the time of preparing the conservation advice.
