Risk and restoration potential for remnant vegetation in salinising landscapes
Hobbs, R. (2003) Risk and restoration potential for remnant vegetation in salinising landscapes. In: National Dryland Salinity Program : inspiration, celebration, aspiration : an R&D workshop recognising the achievements of NSDP Phase 2, Adelaide, SA, Australia, 25 - 26 March pp. 72-75.
While the physiological processes that confer salinity and/or waterlogging tolerance on native species are well understood, few studies in Australia had focused on how native plant communities respond to the development of secondary salinity. Given that remnant vegetation on Australian agricultural land is often small in extent, highly fragmented and likely to be degraded by grazing, weeds and other factors, rising water tables may deliver the final blow to maintaining their ecological activity.
This project aimed to identify effective management priorities and strategies for native vegetation in the lower portions of landscapes, in relation to the risk to vegetation health from rising groundwater and salinisation. We used a mixture of hydrological modelling, field assessment and existing data. Because of the availability of pre-existing data, the project was conducted in the upper and middle Blackwood Basin in Western Australia. One reason for choosing this location is that the south-west of W A has been designated one of 25 world 'hot spots' for biodiversity and the only one in Australia.
