The rehabilitation and/or revegetation of degraded, remnant or post-mining bushland is an increasingly important activity. Data and general principles for the delineation of genetic provenance are urgently required for effective rehabilitation, as well as for the conservation of genetic diversity. We will apply a new and powerful genetic technique for the rapid delineation of provenance in over 30 native plant species in south west Australia. Our aim is to generate provenance guidelines and principles, as well as provenance data for the most important species for bushland rehabilitation, which will be produced for rehabilitation practitioners through a "provenance atlas" book.Read moreRead less
Genetic variation of the vulnerable Eucalyptus argophloia, and its development for sustainable hardwood forestry in low rainfall areas. We will examine the biodiversity in a vulnerable species of eucalypt, Eucalyptus argophloia. This species is under threat due to land clearing, and only 1000 trees remain in the wild. E. argophloia has great promise for plantation timber in low rainfall areas of Northern Australia. We will breed superior varieties for plantation forestry designed to cope with cl ....Genetic variation of the vulnerable Eucalyptus argophloia, and its development for sustainable hardwood forestry in low rainfall areas. We will examine the biodiversity in a vulnerable species of eucalypt, Eucalyptus argophloia. This species is under threat due to land clearing, and only 1000 trees remain in the wild. E. argophloia has great promise for plantation timber in low rainfall areas of Northern Australia. We will breed superior varieties for plantation forestry designed to cope with climate change, low rainfall and salinity. This project will help to manage and preserve the species in the wild and create profitable and sustainable timber plantations on marginal lands.Read moreRead less
Restoration of temperate eucalypt woodland: getting it right. Eucalypt woodlands of southern Australia have been heavily cleared for agriculture: much effort and expense is going towards revegetation of these woodlands to conserve biodiversity, and restore ecosystem services they provide. Current restoration methods are purely empirical, with little understanding of why they work. This project will experimentally investigate revegetation practices to uncover ecological processes they utilise, an ....Restoration of temperate eucalypt woodland: getting it right. Eucalypt woodlands of southern Australia have been heavily cleared for agriculture: much effort and expense is going towards revegetation of these woodlands to conserve biodiversity, and restore ecosystem services they provide. Current restoration methods are purely empirical, with little understanding of why they work. This project will experimentally investigate revegetation practices to uncover ecological processes they utilise, and other ecological processes that potentially can be utilised but are currently not. The cost-effectiveness of different practices will be compared. The outcome of the project will be revegetation practices for eucalypt woodlands that are evidence-based and cost-effective, rather than rule of thumb.Read moreRead less
Forest ecosystem water use: Does species diversity matter? Forest water use and susceptibility to drought are major concerns for forest plantation establishment in Australia. This research will provide fundamental information about how plantation water use and drought tolerance are modified by species diversity. This work has the potential to transform tree plantation establishment practices toward inclusion of greater species diversity or toward species with particular complementary traits. It ....Forest ecosystem water use: Does species diversity matter? Forest water use and susceptibility to drought are major concerns for forest plantation establishment in Australia. This research will provide fundamental information about how plantation water use and drought tolerance are modified by species diversity. This work has the potential to transform tree plantation establishment practices toward inclusion of greater species diversity or toward species with particular complementary traits. It has significant potential to enhance benefits from reforestation projects, including better drought survival, reduced water use, soil bioremediation and enhanced biodiversity. Read moreRead less
Complex system dynamics: restoring riparian and riverine ecosystems. Attempts to restore damaged ecosystems reveal inadequacies in theories describing ecosystem structure and function. For rivers, it is unclear whether theories relating to fluvial geomorphology and ecosystem dynamics are adequate to predict system trajectories following restoration. We will use empirical data on a degraded river to develop cross-scale models of system function, and predict ecosystem structure and dynamics follow ....Complex system dynamics: restoring riparian and riverine ecosystems. Attempts to restore damaged ecosystems reveal inadequacies in theories describing ecosystem structure and function. For rivers, it is unclear whether theories relating to fluvial geomorphology and ecosystem dynamics are adequate to predict system trajectories following restoration. We will use empirical data on a degraded river to develop cross-scale models of system function, and predict ecosystem structure and dynamics following restoration. Following revegetation of riparian habitats and replacement of large woody debris in in-stream habitats of the river, we will test theoretical predictions about changes to physical processes, biotic community assemblage rules and food webs to develop improved ecosystem-based restoration guidelines.Read moreRead less
Rapid genetic delineation of local provenance for effective restoration of urban bushland remnants. Urban bushland remnants are a significant national resource. The rehabilitation of these remnants is a major enterprise drawing on national, state and local resources and substantial community involvement. Best practise recognises that material sourced from the local provenance is critical. Despite this, accurate guidelines on provenance are lacking. We will utilise powerful molecular markers to r ....Rapid genetic delineation of local provenance for effective restoration of urban bushland remnants. Urban bushland remnants are a significant national resource. The rehabilitation of these remnants is a major enterprise drawing on national, state and local resources and substantial community involvement. Best practise recognises that material sourced from the local provenance is critical. Despite this, accurate guidelines on provenance are lacking. We will utilise powerful molecular markers to rapidly generate provenance guidelines for priority species of the Swan coastal plain. We will work closely with restoration practitioners to ensure practical outcomes through adaptive management. Our objective is to generate a provenance atlas for the native plant restoration industry, with benefits flowing nationally.Read moreRead less
Soil physical limitations to growth in sub-tropical hardwood plantations. Large areas of eucalypt plantations are being established to replace native forest wood production in many areas of Australia. A major impediment facing the industry in subtropical eastern Australia is inappropriate site species matching. This is largely due to lack of understanding of the major soil types in the region and the effect on growth of different species. This project will compare site productivity and soil ch ....Soil physical limitations to growth in sub-tropical hardwood plantations. Large areas of eucalypt plantations are being established to replace native forest wood production in many areas of Australia. A major impediment facing the industry in subtropical eastern Australia is inappropriate site species matching. This is largely due to lack of understanding of the major soil types in the region and the effect on growth of different species. This project will compare site productivity and soil characteristics in two major hardwood species and investigate fundamental relationships between soil characteristics and tree root growth. The outcome will be a mechanistic understanding of soil physical limitations to tree growth.Read moreRead less
How much habitat and what configuration maintains natural levels of connectivity in southeast Australian native birds? Maintenance of biodiversity is fundamental to ecologically sustainable development. This project will deepen our understanding of the consequences of landscape change for native birds and enhance our national capacity to integrate nature conservation and agricultural production.

Maintenance of biodiversity is fundamental to ecologically sustainable development. This project will deepen our understanding of the consequences of landscape change for native birds and enhance our national capacity to integrate nature conservation and agricultural production. We will contribute to sustainable use of rural landscapes by providing land managers with greater understanding of (1) how and why landscape change affects bird species diversity and persistence, (2) which components of the landscape can most effectively be manipulated to enhance population survival, and (3) estimating the long-term effects of habitat fragmentation on the population structure and function of species.Read moreRead less
A molecular ecophysiological assessment of the importance of using local provenance seed in plant biodiversity restoration. The rehabilitation of Australia's unique plant diversity, following disturbance, is an increasingly important activity nationally, involving industry, government and community.

The rehabilitation of Australia's unique plant diversity, following disturbance, is an increasingly important activity nationally, involving industry, government and community. The use of local seeds is recognised as best practise, but how local is local? We will use molecular tools to identify the extent of local seed transfer zones, conduct trials to assess the relative performance of local and non-local seeds (is there a home-site advantage?), and assess the consequences of mixing provenances for future generations. We will work closely with industry and community restoration practitioners to improve the effectiveness of restoration, with benefits flowing nationally through general provenance guidelines.Read moreRead less
