The restoration of degraded habitats and seascapes has become a central focus in coastal ecology, and there is an abundance of examples that illustrate diverse benefits for ecosystems, animals and people. Markets are emerging to describe, value, and support investment in, restoration but most are still developing and will benefit from greater consensus on approaches to measure, verify, and account for, seascape recovery. This presentation focusses on restoration projects in the Blue Heart Sunshine Coast, a large (5,000 ha) restoring seascape in eastern Australia. Restoration has commenced at multiple locations in the region, and is expanding rapidly, as local and state governments work in partnership with utility companies and the community to restore former farmlands to tidal wetlands and deliver diverse environmental, social, and economic benefits. Restoration sites are monitored biannually to describe changes in ecosystem extent and condition, biodiversity and habitat services, carbon sequestration and storage, and greenhouse gas emissions and denitrification. Environmental Economic Accounts are also being compiled for some restoring wetlands. We will describe the approaches we have adopted for monitoring, remote sensing and economic accounting, and we will discuss findings, challenges and lessons learned, which may help inform planning, monitoring and developing markets for restoration initiatives.
