Report Type: Preliminary report to CRL Rehabilitation of sites disturbed by mining activities in Australia depends on the effective and efficient use of native seeds. However most native species have evolved dormancy mechanisms so that they only germinate under natural conditions that favour subsequent seedling survival. These conditions may not correspond to those present following broadcasting of seeds during rehabilitation operations. Failure to recruit native species from respread topsoil, broadcast or nursery sown seed on minesite rehabilitation areas is often due to dormancy residing in the seeds. The ACMER and AMIRA are coordinating a collaborating research project between Kings Park Botanic Gardens and the University of Queensland, 'Dormancy Mechanisms in Australian Native Plant Species' to investigate the dormancy mechanisms in Australian native pants with potential for use in minesite rehabilitation. As part of the project, CRL supplied seeds of Boronia safrolifera, Calytrix tetragona, Leucopogon lanceolatus, Monotoca elliptica and M. scoparia as germination of these species was poor. The objective of this study was to assess the viability of the seed lots supplied and to carry out preliminary germination testing.

Soil erodibility is a complex property and is thought of as the resistance of a soil to detachment and transport by the erosive force of a raindrop splash or overland flow. Several attempts have been made to determine criteria for scientific classification of soils according to erodibility but such classifications used for erosion prediction produced only relative rankings. Differences in the natural susceptibilities of soils to erosion are difficult to quantify from field observations. Even a soil with a relatively low erodibility may show signs of serious erosion when it occurs on long or steep slopes or in localities with numerous high-intensity rainstorms (high rainfall erosivity). A soil with a high natural erodibility on the other hand may show little evidence of actual erosion under gentle rainfall when it occurs on short and gentle slopes, or when it is under dense vegetation cover. Currently the best quantitative method for determining the erodibility of a soil in terms of the soil erodibility factor (K) in the Universal Soil Loss Equation (USLE).
