Eucalyptus sargentii: a prospective candidate tree species for climate and salinity mitigation in Western Australia

Mass conversion of native vegetation to agricultural land-use triggered secondary salinity, a hydrological imbalance, which has damaged more than 1.75 million ha of farmland in south-western Australia. Various types of reforestation have been proposed and tested to restore the hydrological balance,...

Description
Summary:Mass conversion of native vegetation to agricultural land-use triggered secondary salinity, a hydrological imbalance, which has damaged more than 1.75 million ha of farmland in south-western Australia. Various types of reforestation have been proposed and tested to restore the hydrological balance, however the economic returns from these cannot compete with existing farm practice and land-holders thus have a reluctance to adopt. An alternative approach has been to reforest abandoned saline areas with salinity and/or water-logging tolerant trees to avoid displacement of farming activities. This reforestation approach is explicitly effective for carbon mitigation and thus finding appropriate tree species is essential. To select suitable tree species, three eucalypt species were planted adjacent to a salt scald in Wickepin, Western Australia, and their survival and growth on a site with saline soil and a shallow (
