This essay introduces eight reports by Dr Hermann Beckler of the nineteenth-century Victorian Exploring Expedition (better known as the Burke & Wills Expedition) from the State Library of Victoria, the Argus newspaper and a German publication. Together, their detail reflects the complexity of the Expedition. Many are also hand-written manuscripts in nineteenth-century script that are difficult to decipher. In Beckler's own words, the reports range from descriptions of the landscape and his journeys, to the plants he observed and collected, and a meteorological report. The detailed medical reports about his return journey to Bulloo provide extensive insight into the grievous suffering of the men (four deaths) in the drought stricken summer of the semi-arid desert north of the Darling River. After he returned home to Bavaria, Beckler published a second medical report on the same subject, translated here by Thomas Darragh.

A study was made over a period of 12 years of the natural regeneration of vegetation along a corridor cleared for the construction of a natural gas pipeline in a semi-arid woodland in central-western New South Wales. Total cover, proportion of grasses, and species composition were assessed on the infilled trench and areas from which topsoil had been bladed, as well as on adjacent undisturbed areas or areas burned by a wildfire. All areas were grazed continuously by sheep under normal station management. The effects of mechanical disturbance and of burning on individual species were measured in terms of species dominance and occurrence. Some insight was also gained in to the successional process on bared sites and in to the effects of the timing of seasonal rainfall on species composition. Of the 75 major species recorded, 15 were found to have greater occurrence on trenched sites, 46 decreased in occurrence and 14 showed no clear trend. Perennial grasses and small annual plants were the main decreasers, whilst Medicago spp., Erodium crinitum, Hordeum leporinum and certain 'weedy' annuals were the main increasers. Some of the early colonisers lasted only a few years or even less in any quantity, thereafter to be replaced by other increasers. Burning had little effect on the long-term occurrence of Stipa variabilis, Wahlenbergia spp., Helipterum spp., Calotis cuneifolia and some minor species. Eragrostis lacunaria appeared to decrease, while several annual plants were more common on burned areas.
