Marrawah Skipper) This Conservation Advice was approved by the Minister on 2 February 2011 Approved Conservation Advice for Oreisplanus munionga larana (Marrawah skipper) (s266B of the Environment Protection and Biodiversity Conservation Act 1999) 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 Oreisplanus munionga larana, Family Hesperiidae, also known as the Marrawah skipper, is a brightly coloured skipper. Skippers are usually considered to be butterflies, but are intermediate between butterflies and moths. This subspecies is rich caramel above with pale yellow wing markings and pale yellow below. The females tend to be larger, slightly paler and more yellowish on the underside (Couchman, 1962; Braby, 2000). The species is found as two subspecies, Oreisplanus munionga munionga found in the mountains of New South Wales and Victoria and Oreisplanus munionga larana found on the north-west coast of Tasmania (Braby, 2000). Conservation Status The Marrawah skipper is listed as vulnerable. This species is eligible for listing as vulnerable under the Environment Protection and Biodiversity Conservation Act 1999 (Cwlth) (EPBC Act) as it has a limited geographic distribution which is precarious for its survival due to severe fragmentation and ongoing threats (TSSC, 2010). The species is listed as endangered under the Tasmanian Threatened Species Protection Act 1995. Distribution and Habitat The Marrawah skipper is endemic to Tasmania, occurring only in far north-western to western Tasmania with disjunct locations on the north coast at Stanley (probably extinct) and south of Penguin (about 77 km east of Stanley). The species is known from 14 populations with an estimated extent of occurrence of 3710 km2, although this could be smaller if large areas of unsuitable habitat are excluded. It has an estimated area of occupancy of 0.2 km2, and estimated total population size of less than 10 000 (Neyland, 1994). This species occurs within the King IBRA Bioregion and the North West Natural Resource Management Region. The other subspecies, Oreisplanus munionga munionga, is found in the mountains of New South Wales and Victoria. The distribution of this species is not known to overlap with any EPBC Act-listed threatened ecological community. Threats The main identified threats to the Marrawah skipper are cattle grazing and clearance of habitat to create intensively managed grazing ground (Bell, 2002; Harris and Kitchener, 2005). Other threats include inappropriate disturbance regimes from slashing, weed invasion, fire and recreation. The main potential threat to some parts of the species’ range is loss of habitat due to land clearing for forestry operations (Bell, 2002). Oreisplanus munionga larana (Marrawah skipper) Conservation Advice Page 1 of 4 This Conservation Advice was approved by the Minister on 2 February 2011 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 programs. 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. Regional Priority Actions The following regional priority recovery and threat abatement actions can be done to support the recovery of the Marrawah skipper. Habitat Loss, Disturbance and Modification Monitor known populations to identify key threats. Monitor the progress of recovery, including the effectiveness of management actions and the need to adapt them if necessary. Identify populations of high conservation priority. Ensure there is no disturbance in areas where the Marrawah skipper occurs, excluding necessary actions to manage the conservation of the species. Investigate formal conservation arrangements, management agreements and covenants on private land, and for crown and private land investigate inclusion in reserve tenure if possible. Invasive Weeds Develop and implement a management plan for the control of Cirsium arvense and other identified weeds in the region. Ensure chemicals or other mechanisms used to eradicate weeds do not have a significant adverse impact on the Marrawah skipper. Fire Develop and implement a suitable fire management strategy for the habitat of the Marrawah skipper. Identify appropriate intensity and interval of fire to promote seed germination and/or vegetation regeneration of Carex appressa. 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 Marrawah skipper within the local community. Maintain liaison with private landholders and land managers of land on which populations occur. Enable Recovery of Additional Sites and/or Populations Investigate options for linking, enhancing or establishing additional populations. Local Priority Actions The following local priority recovery and threat abatement actions can be done to support the recovery of the Marrawah skipper. Habitat Loss, Disturbance and Modification Control access routes to suitably constrain public access to known sites on public land. Suitably control and manage access on private land. Minimise adverse impacts from land use at known sites. Protect populations of the listed species through the development of conservation agreements and/or covenants. Oreisplanus munionga larana (Marrawah skipper) Conservation Advice Page 2 of 4 This Conservation Advice was approved by the Minister on 2 February 2011 Invasive Weeds Identify and remove weeds in the local area, which could become a threat to the Marrawah skipper, using appropriate methods. Manage sites to prevent introduction of invasive weeds, which could become a threat to the Marrawah skipper, using appropriate methods. 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’ habitat. Where appropriate, manage total grazing pressure at important/significant sites through exclusion fencing or other barriers on private land, state and public reserves, conservation areas, and state forests. 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 Marrawah skipper, but highlights those that are considered to be of highest priority at the time of preparing the Conservation Advice.

Neolucia hobartensis albolineata ssp. nov. is illustrated, diagnosed, described and compared with the nominate subspecies N. hobartensis hobartensis (Miskin, 1890) from Tasmania and N. hobartensis monticola Waterhouse & Lyell, 1914 from northern New South Wales, Australia. The new subspecies is restricted to montane areas (mainly >1000 m) in subalpine and alpine habitats on the mainland in southeastern Australia (southern NSW, ACT, VIC) where its larvae specialize on Epacris spp. (Ericaceae). It thus belongs to a distinct set of 22 butterfly taxa that are endemic and narrowly restricted to montane areas (>600 m, but mainly >900 m) on the tablelands and plateaus of mainland southeastern Australia. Monitoring of these taxa, including N. hobartensis ssp., is urgently required to assess the extent to which global climate change, particularly temperature rise and large-scale fire regimes, are key threatening processes.

Scientific name (common name) Oreisplanus munionga larana (Marrawah skipper) The species is found as two subspecies, Oreisplanus munionga munionga found in the mountains of New South Wales and Victoria and Oreisplanus munionga larana found on the north-west coast of Tasmania. 2. Description The Marrawah skipper is a brightly coloured skipper. Skippers are usually considered to be butterflies, but are intermediate between butterflies and moths. This skipper is rich caramel above with pale yellow wing markings and pale yellow below. The females tend to be larger, slightly paler and more yellowish on the underside. The Marrawah skipper occurs in any vegetation types dominated by the native sedge Carex appressa or with an understorey dominated by C. appressa. Habitat includes remnant patches of C. appressa in disturbed areas such as those grazed by cattle or along drains. Eggs are laid on the leaves of C. appressa, which provides food and shelter for the larvae. All sites are at low altitudes and most are in very near coastal areas. 3. National Context The Marrawah skipper is endemic to Tasmania, occurring only in far north-western to western Tasmania with disjunct locations on the north coast at Stanley (probably extinct) and south of Penguin (about 77 km east from Stanley).

  • 16B. from Moonlight Jewels to Common Browns: Butterfly
    From Moonlight Jewels to Common Browns: Butterfly accounts for the ACT Suzi Bond1 and Michael Vardon2 1 Australian Bureau of Statistics, [email protected] 2 Australian National University, [email protected] Abstract We present a set of novel SEEA butterfly accounts for the Australian Capital Territory (ACT), Australia. These accounts identify the theoretical and practical issues in producing biodiversity accounts and assess the implications of such biodiversity accounts for public policy and the management of species and public areas in the ACT and beyond. The accounts are to be used in ACT State of Environment reporting and considered for broader national biodiversity application. The butterfly accounts span from 1978 to 2018, and the data sources and methods underpinning the accounts are detailed in the paper. The accounts aim to eventually include butterfly species presence and abundance by habitat type and season for each survey year and between two points in time, butterfly species area of distribution by habitat and a land cover account. These types of biodiversity accounts will support the development of the SEEA-EEA framework and the UN ambition to elevate the system to an international standard. They demonstrate the flexibility of SEEA for presenting a range of ecosystem and environmental information. 1 1. Introduction The best method for including biodiversity in the System of Environmental Economic Accounting (SEEA) has been a vexing question for more than a decade. The specific call for including biodiversity values in national accounts in Target 2 of the Biodiversity Strategy Plan (2011-2020) for the Convention on Biological Diversity provided an impetus for this work and also coincided with the processes for elevating the SEEA Experimental Ecosystem Accounting (EEA) to an international statistical standard.

    Threatened Species Link www.tas.gov.au SPECIES MANAGEMENT PROFILE Oreisplanus munionga subsp. larana Marrawah Skipper Group: Arthropoda, Insecta (insects), Lepidoptera (butterflies, moths), Hesperiidae (Skippers) Status: Threatened Species Protection Act 1995: endangered Environment Protection and Biodiversity Conservation Act 1999: Vulnerable Endemic Found only in Tasmania Status: The Marrawah Skipper (Oreisplanus munionga subsp. larana) is a brightly coloured butterfly, rich caramel brown above with pale yellow wing marking and pale yellow below. The Marrawah Skipper is a subspecies which is endemic to Tasmania; another subspecies is found in alpine areas of mainland Australia. Known only from the coastal and near-coastal areas of the northwest coast of Tasmania, it is exclusively associated with the tussock-sedge Carex appressa, which is its larval host and food plant. Its habitat ranges from dense Carex appressa sedgeland (e.g. along drains and forest margins) and swamp forest to plantations and pasture. The main threats to the Marrawah Skipper are clearing of coastal and near-coastal habitat, further fragmentation of subpopulations, and inappropriate disturbance including cattle grazing, weed invasion and forestry. The objectives for managing this subspecies include protection of known subpopulations, location of other subpopulations, and increasing understanding of the species' ecology. A complete species management profile is not currently available for this species. Check for further information on this page and any relevant Activity Advice. Key Points Important: Is this species in your area? Do you need a permit? Ensure you’ve covered all the issues by checking the Planning Ahead page. Important: Different threatened species may have different requirements. For any activity you are considering, read the Activity Advice pages for background information and important advice about managing around the needs of multiple threatened species.
