Practical methods of riparian rehabilitation on salinized lands: an evaluation of four year old riparian revegetation trials
An evaluation of revegetation sites on two properties on the Kalgan River WA which were implemented in 1995 to rehabilitate salinized land compared the relative success of direct seeding and seedling planting. Both sites indicate that careful ground preparation is critical to long term viability. Areas revegetated using direct seeding methods have achieved dense stands of canopy and understorey plants and exhibit structural and species diversity. Areas of planted seedlings have suffered significant loss from stock intrusion and increasing salinity in low lying areas, and in some cases, poor soil preparation (A).
Guidelines for the rehabilitation of riparian vegetation in southeastern Australia
Guidelines for the restoration of riparian vegetation in southeastern Australia, based on extensive research into the characteristics of riparian vegetation in undisturbed catchments, are presented, including an outline of the multiple factors which need to be considered when embarking on a revegetation program. The need for maintaining genetic integrity and biodiversity by planting indigenous species is emphasized, and four methods for selecting appropriate species for different situations are discussed. Standard planting methods are also considered, including several experimental approaches which are cost-effective, reduce disturbance of the riparian corridor and reduce the need for follow-up maintenance (A).
