To restore and conserve the unique and diverse ecosystems of Eyre and Yorke Peninsulas both regions have adopted a collaborative, landscape-scale planning approach to biodiversity conservation.  This process has identified important biodiversity assets and developed strategies for their future care and maintenance.  Several open woodland and mallee vegetation communities have been identified as important assets for regional conservation goals.

Targeted revegetation is part of WildEyre’s and Southern Yorke Peninsula’s integrated strategies to restore the extent and functionality of these plant communities.  While these revegetation activities may be designed for ecological benefits, they also have the potential to provide co-benefits to the community and individual landholders through the sequestration of atmospheric carbon dioxide and access to carbon markets.  Estimates of carbon sequestration rates from targeted revegetation activities in the region can assist planners and landholders to evaluate the potential economic value of these new assets through carbon markets.

To guide future landuse planning and investment decisions spatial-temporal models of carbon sequestration from revegetation have been recalibrated for priority vegetation communities in both regions.  Maps of estimated carbon sequestration rates from potential targeted revegetation activities at 25 and 45 years of age have been generated under historic climatic conditions.  Models have also been used to explore the likely impact of several climate change scenarios on carbon sequestration, plant mortality and vegetation structure across both regions.
