The ecology and conservation management of the ptunarra brown butterfly Oreixenica ptunarra (Lepidoptera; Nymphalidae; Satyrinae) in Tasmania, Australia

  title={The ecology and conservation management of the ptunarra brown butterfly Oreixenica ptunarra (Lepidoptera; Nymphalidae; Satyrinae) in Tasmania, Australia},
  author={Mark G. Neyland},
The ecology and conservation status of the rare Tasmanian endemic butterfly Oreixenica ptunarra Couchman was investigated over a three-year period. One hundred and fifty colonies of the butterfly have been located in areas of Poa-dominated native grassland across central Tasmania. Most colonies are small and all are under pressure from continuing stock grazing. Without active intervention the species will continue to decline. A recovery plan for the butterfly has been written, implementation of… 
The effects of introduced vespid wasps (Vespula germanica and V. vulgaris) on threatened native butterfly (Oreixenica ptunarra) populations in Tasmania
An increase in the intensity of wasp control, in combination with other conservation management methods, is required for the protection and recovery of O. ptunarra without ongoing conservation measures, it is likely that butterfly numbers will stay low, potentially leading to genetic bottlenecks and more local extinctions.

The values of documenting and defining changes in lepidopteran assemblages (for example, through analysis of light-trap catches of moths) as correlates of environmental change are outlined and examples of such umbrella Lepidoptera from the Australian region are given.
Threatened stag beetles in Tasmania's production forests : single-species studies contributing to biodiversity conservation
The distribution, habitat and conservation requirements of three species of stag beetles listed under the schedules of the Tasmanian Threatened Species Protection Act 1995, Hoplogonus simsoni, Lissotes latidens, and L. menalcas, were investigated in order to inform the development of management strategies for the conservation of their habitat throughout production forests.
Butterflies in a Disappearing Ecosystem: Alpine Satyrinae
Australia’s alpine and subalpine zones are small, confined to the southeast of the continent and, by European or other standards, not particularly high: the highest peak (Mt Kosciuszko) reaches only

Strategic national approach for improving the conservation management of insects and allied invertebrates in Australia
A novel educational, regional approach based on selecting, for each of the 89 IBRA regions, a relatively small set of ‘flagship taxa’ (threatened species and/or ‘iconic’ species of high scientific/social value), which are then promoted and/ or nominated for listing by the scientific community is proposed.
Development and evaluation of predictive habitat models to assist the conservation planning of a threatened lucanid beetle, Hoplogonus simsoni , in north-east Tasmania
The use of predictive habitat distribution models by land managers in the conservation management of threatened species is increasing. Few models, however, are subsequently field-checked and
Livestock grazing management and biodiversity conservation in Australian temperate grassy landscapes
Although there is an increasing desire to find management strategies that protect and enhance biodiversity without hindering long-term agricultural production, in many cases this may not be possible and current knowledge suggests that compatibility is most likely to be achieved using low-input systems in low productivity landscapes, whereas in highly productive landscapes there is less opportunity for integration of productive land-use and biodiversity conservation.
Modeling the distribution of odonates: a review
An overview of species distribution models is provided and potential future areas where use of SDMs can advance knowledge of odonate–environment interactions are highlighted, including effects of limited taxonomic coverage and limited spatial resolution at fine scales.


The Pre-European vegetation of the Midlands, Tasmania: a floristic and historical analysis of vegetation patterns
Some 83% of the area of native vegetation of the Tasmanian Midlands has been replaced after 170 yr of agricultural exploitation, but scattered remnants of the native vegetation still exist. The
The relationships among eucalypt forest, grassland and rainforest in a highland area in north‐eastern Tasmania
Changes in the vegetation of a highland area of north-eastern Tasmania are described and related to a change 150 years ago from Aboriginal to settled land use. Expansion of rainforest dominated by
A method for assessing changes in the abundance of butterflies
A method based on transect count has been developed to assess changes in abundance of butterflies from year to year, and provides considerable information on the phenology and ecology of butterflies.
A natural regions map for Tasmania
Tasmania has been divided into 13 regions for the purpose of mapping plant distribution. Eleven of these regions are large ecogeographic zones, the other two being defined to accommodalc historic
Land use on the Central Plateau with special reference to the grazing industry
Regional land-use planning is a relatively new concept in Tasmania. At present no land-use plans are in operation, though it is the intention of the new Labor Government to legislate for a State
