Project Description

The reconstruction of saltmarsh at Penrhyn Estuary, Botany Bay, Sydney for migratory shorebirds is an insightful case study that details the process of accommodating habitat shifts in an industrially impacted intertidal zone. Project planner Geoff Sainty effused about the 15 year long project, ‘if there’s any chance to get involved in working with saltmarsh get into it, because it’s loaded with variables, you’ll never get smart, but you’ll have a lot of time…it’s a brilliant area to work in’.
