- Description: Collembola and other invertebrates were collected using a number of methods from three main locations in the Pungalina–Seven Emu survey area between 09 July and 21 July 2012. Specimens were identified to Order except for Collembola which were identified to species or morphospecies. Most invertebrates collected belong to highly dispersive taxa such as Diptera, Hemiptera and Coleoptera. Invertebrates were collected from two caves in the survey area; in the caves invertebrates were fairly abundant and species rich and included new species. Thirty-three collembolan species were collected, a third of which were found only on sites protected from fire such as rocky outcrops and creek banks. Symphypleona genera such as Corynephoria, Prorastriopes and Temeritas, normally abundant on native grasses and in leaf litter of forests and woodlands of the dry/wet savannah tropics were totally absent. It is suggested that the increased frequency of planned burns in the region are the cause.

- Description: Summary 1. The distributions of Collembola on the Warra-Mount Weld Altitudinal Transect were investigated based on samples taken from February–April 2001, November–December 2001 and January– February 2002. 2. The Collembola of the Warra-Mount Weld Altitudinal Transect was species rich with more than 40 species collected; the majority of species recorded have not been described. 3. Most of the species collected are considered endemic to Tasmania and some endemic genera were present. 4. The Malaise traps performed well indicating that a suite of species are arboreal and highly vagile. 5. No exotic (introduced, alien) species were detected in this study indicating that the area sampled has been little disturbed and is of high conservation value. 6. Altitudinal trends were evident with a small number of species only occurring at the high altitudes and others only at low altitudes. Only a few species appeared to occur at all altitudes sampled. 7. Ordination plots showed that Collembola assemblages at lower altitude sites on the Warra transect were more similar to each other than those at the higher altitude sites on Mount Weld which formed three clusters: 1100; 1200 and 1300 m; and 800, 900 and 1000 m. 8. Mount Weld sites 600 and 700 m faunas were most similar to Warra sites so forming a continuum in altitudinal zonation between Warra and Mount Weld. 9. PERMANOVA analysis of monthly pitfall catches in 2001 and 2002 showed differences between months and altitudes on both transects and that the differences between months were more distinct at the lower altitude Warra sites than on the higher altitude Mount Weld sites. This difference was particularly marked for the month of February, which was the only month surveyed in both years. 10.Much of the change in faunal assemblages along the Warra and Mount Weld altitudinal transect seemed to be the result of changes in vegetation cover. The most abrupt faunal transitions took place across the tree line between 1000 and 1100 m and a smaller change from lowland forest to subalpine woodland on the Mount Weld transect. 11.Much material in the pitfalls was in very poor condition because of the long trapping time with unsuitable preservative so could not be identified to species but rough estimates were made of numbers of individuals in each family or genus.
