Stream Stabilisation or Rehabilitation is a guide to good practice in stream stabilisation and rehabilitation of north-east Queensland coastal streams. The majority of existing stream management guidelines are not entirely suitable for that purpose. Many focus on approaches to streambank stabilisation that give scant regard to ecological or aesthetic objectives. Others provide little on the principles, procedures and methods essential to good practice. Many of the existing guides were developed for other environments, principally temperate North America and Europe. Until now, virtually nothing has been available for the quite different tropical stream systems, particularly those of north-east Queensland.

This bulletin describes the results of a modelling study of evaporation from farm dams and a 'ready reckoner' in the form of a spreadsheet that: Calculates the cost of installing an evaporation reduction system Calculates how much water is saved from evaporating.

The Wetting Front Detector (WFD) is a new tool to help measure how deeply water has penetrated into the soil after an irrigation event. The WFD also captures and stores a soil water sample, which can be analysed for its salt or nutrient content. The first commercial version of the Wetting Front Detector (WFD), called the FullStop, was released in 2004. The Full Stop WFD is comprised of a funnel, a filter and a float mechanism. The funnel 'captures' some water from the wetting front as it goes past, and pops up an indicator flag at the soil surface. If the soil is dry before irrigation, the wetting front will not penetrate deeply, because the dry soil absorbs much of the infiltrating water. A long irrigation would be needed to activate a detector. However, if the soil is relatively wet before irrigation, the wetting front moves more deeply into the soil. Experiments with sprinkler irrigation have confirmed this.

Many of the research projects commissioned by the National Program for Sustainable Irrigation (NPSI) have adopted innovative approaches to achieve strong connections between the researchers and the rest of the community. Finding ways to include the practical knowledge that comes from the community into research is crucial to achieving a sustainable future. This research bulletin outlines approaches to engaging with communities that have been successfully developed and applied by NPSI projects. The complementary nature of the processes is emphasised.

This hand book has been produced from the results of wetland research projects funded by the Land and Water Resources Research and Development Corporation (LWRRDC) and Environment Australia, in association with the New South Wales Department of Land and Water Conservation (DLWC) and Botany, University of New England (UNE). The information contained in this publication has been published by LWRRDC to assist public knowledge and discussion and to help improve the sustainable management of land, water and vegetation. Where technical information has been prepared or contributed by authors external to the Corporation, readers should contact the authors, and conduct their own enquiries before making use of that information.

There has never been greater public investment in natural resource management (NRM) in Australia, or in research that provides the information and knowledge to improve it. A challenge exists to ensure that this ever increasing knowledge base is used to make on-ground decisions.

The biodiversity research in Grain & Graze focuses on the relationships between biodiversity (plants, animals, insects and microorganisms) and on-farm production. Over many years, monitoring four paddocks with different land uses on 47 mixed farms, the project will contribute to answering the following questions: * Does enterprise diversity on-farm lead to increased biodiversityΓ * Is there a relationship between site conditions, land use, landscape, terrain and biodiversityΓ Results of the long term research should inform farmers about what can be done to maintain and enhance

Watershed Torbay was established in 2001 as a national demonstration project to undertake whole of catchment waterways restoration. Funded by Land & Water Australia through the former National Rivers Consortium, the aim was to further develop and test approaches to waterways management at a whole catchment, rather than river reach scale, and to share the learnings and successes throughout Australia.
