Managing variable retention harvesting to maintain forest biodiversity—effects of forest influence and successional stage on recolonisation. The project will provide the ecological evidence that will allow forest harvesting practices to be designed to sustain the full range of biodiversity in managed forest systems. It therefore will provide the basis for sustainable forest management, with extensive economic implications.

The project will provide the ecological evidence that will allow forest harvesting practices to be designed to sustain the full range of biodiversity in managed forest systems. It therefore will provide the basis for sustainable forest management, with extensive economic implications. It will specifically test the biodiversity implications of the new and increasingly important variable retention methods of forest harvesting, and provide the basis for optimising these methods. In addition, the large database of DNA barcodes for forest beetles developed as a by-product by this project will provide a basis for less expensive and more accurate biodiversity assessments in sustainable management of forest systems in general.Read moreRead less
Site factors and genotype-site interaction affecting growth of eucalypt hybrids bred for commercial agro-forestry as a salinity management tool. Preliminary results indicate that with appropriate site-genotype matching, commercial plantation forestry can be pushed well below the current limit (650-700mm/yr). Outcomes from this project will potentially facilitate doubling of Australia's forest plantations, eliminate the annual trade deficit of $2 billion in forest products; ensure the long term e ....Site factors and genotype-site interaction affecting growth of eucalypt hybrids bred for commercial agro-forestry as a salinity management tool. Preliminary results indicate that with appropriate site-genotype matching, commercial plantation forestry can be pushed well below the current limit (650-700mm/yr). Outcomes from this project will potentially facilitate doubling of Australia's forest plantations, eliminate the annual trade deficit of $2 billion in forest products; ensure the long term environmental and productive sustainability of our agricultural production systems; diversify and drought proof farm income through the introduction of perennial tree crops whose yield and harvest is independent of short term seasonal fluctuations; and re-invigorate the economy of rural Australia brought about by investment in new, inland forest and wood processing industries.Read moreRead less
The Sustainable Effluent Irrigation Project - Effects of effluent irrigation on soil sodicity and groundwater quality. The land application of recycled municipal effluent is now regularly practised by a number of local authorities and agencies responsible for centralised collection of wastewater, its treatment and disposal. Treated municipal effluent is often land applied and used to grow hardwood plantations. Hardwood plantations are very effective in producing large amounts of biomass and also ....The Sustainable Effluent Irrigation Project - Effects of effluent irrigation on soil sodicity and groundwater quality. The land application of recycled municipal effluent is now regularly practised by a number of local authorities and agencies responsible for centralised collection of wastewater, its treatment and disposal. Treated municipal effluent is often land applied and used to grow hardwood plantations. Hardwood plantations are very effective in producing large amounts of biomass and also assist agencies in off-setting wastewater treatment and disposal costs associated with advanced wastewater treatment to remove nutrients. This project will examine the effects of effluent irrigation on soil chemistry and groundwater quality at two hardwood plantations in the Hunter Valley, NSW. It is increasingly clear that large-scale reuse schemes, particularly those involving hardwood plantations, must be designed to be sustainable and have no significant impact on soil chemistry (increasing sodicity) and groundwater. This project will develop irrigation regimes for hardwood plantations which will promote soil productivity and optimize effluent application rates for pollutant removal and biomass production.

Understanding the health effects of landscape burning and biomass smoke in Australian towns and cities. Bushfires are increasingly affecting Australian towns and cities directly and indirectly from episodes of severe air pollution. An approach to manage bushfires is to reduce fuel loads by setting planned fires under stable weather conditions, yet this strategy is controversial because of community concerns about ecological sustainability and negative health impacts from smoke. The relative im ....Understanding the health effects of landscape burning and biomass smoke in Australian towns and cities. Bushfires are increasingly affecting Australian towns and cities directly and indirectly from episodes of severe air pollution. An approach to manage bushfires is to reduce fuel loads by setting planned fires under stable weather conditions, yet this strategy is controversial because of community concerns about ecological sustainability and negative health impacts from smoke. The relative importance of air pollution from planned and unplanned bushfires vs. wood heaters, agricultural burning and other sources of air pollution will be determined. Our study will enable evidence-based bushfire smoke management, help formulate national air quality standards and shape policies regarding biomass smoke and bushfire management.Read moreRead less
Forestry effects on headwater ecosystem health: a multi-catchment experiment. Most catchments in southern Australia have been logged historically. Increasingly, native forest harvesting occurs in regrowth or drier areas. Although foresters have empirical data on ecological effects of harvesting in pristine or wetter catchments, little exists for drier regrowth areas, hampering effective management to minimize impacts on stream ecosystem health. This project will supply ecological data on stre ....Forestry effects on headwater ecosystem health: a multi-catchment experiment. Most catchments in southern Australia have been logged historically. Increasingly, native forest harvesting occurs in regrowth or drier areas. Although foresters have empirical data on ecological effects of harvesting in pristine or wetter catchments, little exists for drier regrowth areas, hampering effective management to minimize impacts on stream ecosystem health. This project will supply ecological data on stream ecosystems to supplement 4 years of hydrological data collected by Forests NSW from 5 experimental catchments. Results will provide a firmer scientific basis for ecologically sustainable harvesting in this forest type, with flow-on benefits to our national economy, biodiversity, and environment.Read moreRead less
The impact of water logging on mitochondrial metabolism in leaves and roots of Grey poplar. Water logging and flooding are seasonal occurrences in a variety of environments. These events cause various damage to environments, including damage to plants. The damage to plants has traditionally been associated with annuals, such as various crop species. However larger plants, i.e. trees, are also very susceptible to water-logging and flooding.

Water logging and flooding are seasonal occurrences in a variety of environments. These events cause various damage to environments, including damage to plants. The damage to plants has traditionally been associated with annuals, such as various crop species. However larger plants, i.e. trees, are also very susceptible to water-logging and flooding. As it can take from several years to decades for tress to be established it is important to understand how trees can withstand water-logging and flooding. As tree plantation are uses for commercial and environmental purposes this knowledge will be useful to a broad spectrum of users in the community.Read moreRead less
Bushfire smoke and the relationship between human and landscape health. A team of landscape ecologists, environmental chemists and public health specialists will determine the ecological causes and adverse health effects of different levels of bushfire smoke in Darwin.
