Native Vegetation

Enhancing and utilising landscape heterogeneity to meet multiple land use objectives

The broad aim of the project was to provide land managers with information that will encourage them to further value, protect and enhance vegetation diversity by demonstrating the practical benefits that can be derived from this natural asset in Australian rangelands. Vegetation diversity and local climate influences combine to produce differences between regions in the patterns of plant growth from year to year, such that the timing of droughts and favourable years can vary between regions. We set out (more)...

Plants and Animals of Kija and Jaru Country

Aboriginal knowledge conservation and ethnobiological research in the upper Ord catchment, Western Australia

Landscape changes and concerns about country as expressed by traditional owners on country are presented in chapter three. The bulk of the ethnobiological research and knowledge conservation is presented in chapter four, Kija plants and animals, and in chapter five, Jaru plants and animals. Recommendations for the completion of the plant and animal knowledge project for each language is presented in chapter six. Acknowledgments, an outline of data sets collected (more)...

The fourth dimension: incorporating time into landscape-level biodiversity assessments

A fundamental issue in ecological research is measuring spatial and temporal variation in natural systems in order to assess the effect and magnitude of anthropogenic disturbances. While spatial variation is measured routinely, most ecological studies do not measure temporal variation: sampling is usually limited to relatively short periods and rarely has temporal replication. This not only devalues the spatial comparisons because historical levels of variability are not considered but also precludes (more)...

Maximising woodland bird diversity in Brigalow Bird forests

Final technical report

Large continuous areas of woodland, such as the eucalypt woodlands of the Brigalow Belt, are potentially significant refugia for fragmentation-sensitive birds, and the area of these woodlands under private and public conservation management is increasing substantially. Yet the avifauna of the apparently relatively intact woodlands shows many of the symptoms typically associated with fragmented agricultural regions, such as domination by a single species, the aggressive noisy miner.

Molecular ecological analysis of vegetation function in fragmented Australian biomes

The aims of this project were to quantify the strength and scale of reproductive interactions among native plant populations occupying remnant vegetation patches in fragmented cropping landscapes in NSW and WA, assess their demographic significance in terms of progeny fitness and population viability and from this develop models of inter-patch interactions in relation to landscape configuration.

Maximising woodlands bird diversity in Brigalow Belt forests

Final report

The Brigalow Belt is a national biodiversity hotspot, and its extensive forests and woodlands are potentially significant refugia for fragmentation-sensitive birds, but our understanding of optimal management for biodiversity conservation and the specific threats facing woodland birds in the area is limited. In particular, management of the aggressive noisy miner is a major challenge throughout the region, despite the species typically being associated with fragmented landscapes. This project aimed to (more)...

Mastering vegetation management for both conservation and profit

The widespread adoption of agroforestry and native vegetation management is seen as a means of supporting agricultural productivity; increasing the resilience of farming businesses in the face of increasingly uncertain climate and market conditions; reducing the environmental impacts of agricultural management; and enhancing regional biodiversity, aesthetic and cultural values.

Achieving Coordinated Landscape-scale Outcomes with Auction Mechanisms

The broad aim of the project was to provide land managers with information that will encourage them to further value, protect and enhance vegetation diversity by demonstrating the practical benefits that can be derived from this natural asset in Australian rangelands.

Thinking Bush - Issue 9

Knowledge for managing native vegetation in Australian landscapes

Thinking Bush, edition 9 is the final edition of this quarterly magazine produced out of the Native Vegetation & Biodiversity program.

Carbon Uptake and Water Use of Vegetation Under Climate Change

Accumulation and storage of carbon in trees is one method of sequestration which may help offset increasing atmospheric CO2 concentrations. However, for every molecule of CO2 absorbed by a leaf, up to a thousand molecules of water are released as transpiration, water that has moved out of the soil into the atmosphere. Therefore, simply planting more trees to absorb more CO2 is not as risk-free as may originally be thought, (more)...
