The potent germination stimulant, known as butenolide, is expected to provide substantial benefits for improving seed germination and seedling vigour of many plant species used in agriculture, land restoration and rehabilitation. Currently, little is known about the stability, persistence and distribution of the butenolide in natural environments and the mechanism of seed dormancy breaking. This study now provides a unique opportunity for Australian research to establish a world-leading position in understanding the processes that regulate seed dormancy, particularly in relation to post-mining land rehabilitation. The research findings will also have wider application in plant conservation, weed control and crop production.Read moreRead less

The knowledge and practical outcomes generated from this project will facilitate more effective restoration of degraded native ecosystems through the return of a wider range of key understorey plant taxa and more efficient use of seed supplies. Availability of a broader suite of species will increase biodiversity, improve ecosystem resilience to change, and help in the conservation and recovery of nationally threatened taxa. By increasing the range of species with horticultural potential available for commercial propagation, it will also reduce the harvest of wild flowers. More efficient production and use of seed stocks will reduce the pressure on limited seed resources from seed harvesting.Read moreRead less
Polymetallic phytoextraction applied to mine waste. Phytoextraction involves the use of hyperaccumulator plants to grow and concentrate a metal. Subsequently, the crop is harvested and the metal extracted. The aim of this research is to investigate the uptake and chemically induced uptake of heavy metals (Ni, Co, Au, Ag, Cu, Pb, Zn, Pt, Pd, Cr) by plants grown on mine tailings and mine waste materials. Outcomes will include practical methods of metal extraction that are cheap to employ where met ....Polymetallic phytoextraction applied to mine waste.

Nickel is an essential metal for many technologies, and a key component of Australia's resource industry. Nickel exports contribute in excess of Aus$2 billion per annum to the economy. To date, most of Australia's Ni production has come from sulphide ores but the current development of large lateritic Ni operations in Western Australia will result in most production coming from lateritic Ni ore. Hence increasing the research effort on ecological restoration of these large opencast mines is essential to ensure an environmentally sustainable Australia. This project will set up strategies to maintain biodiversity using geochemical and biological technologies to minimise environmental risk.Read moreRead less
Devising ecologically sustainable restoration programs for degraded rural landscapes by integrating landscape ecology, genetics and ecophysiology.

Concern about tree decline in rural landscape is widespread, and disturbingly climate change is predicted to exacerbate this problem. Past ill-considered tree plantings have proven to be economically wasteful, achieved limited ecological resilience and negligible improvement of biodiversity values. Using Tasmania as a 'model system', we will advance this problem by undertaking research to determine how seedling establishment, tree growth, carbon storage and water use are influenced by landscape setting, management history, climate change, species type and local varieties. This research will provide a much needed evidence to devise ecologically sustainable tree-plantings in southern Australia.Read moreRead less
