... and abundance have been linked to the direct and indirect impacts of pastoralism. Grazing by livestock is the main “direct” impact of pastoral activity and has resulted in widespread changes in habitat structure and a decrease in primary productivity. The loss in primary productivity may have reduced...

... in population densities where grazing has occurred. There has also been some fragmentation of populations in the south eastern parts of the study area in response to clearing for cropping. It is envisioned that the modelling will be used to predict the impacts of various landuse proposals for the region being...

... The black rat is among the world's worst vertebrate pests. Yet very little is known of its impacts or potential impacts on biodiversity in Australian ecosystems. In this paper we examine the impacts of black rats on biodiversity values at North Head, Sydney where a wildlife sanctuary is planned...

... The impacts on rainforest fauna of internal fragmentation caused by clearings for linear infrastructure such as roads, highways and powerlines have been examined in the tropical rainforests of the Wet Tropics in far north Queensland. The impacts include habitat loss through clearing and edge...

... The direct impacts of logging on the arboreal, solitary brush-tailed phascogale were investigated in jarrah forest in south-western Australia. Individuals were monitored before, during and after logging in the Kingston Forest in 1995. The study was complicated by the effects of a drought...

... Cattle have been grazed in the forested areas of northern NSW for over 150 years. While this practice is considered to have significant benefits for forest management and the local economy, the combined effects of grazing and fire has raised concerns about the impact of this composite management...
