Richmond Park is a ~65ha saltmarsh-dominated seascape area, located near Hobart (Tasmania, Australia), and part of the Pitt Water-Orielton Lagoon Ramsar Wetland of International Importance. The marsh is subject to both river and diurnal micro-tidal flows, with the main passageway of these flows altered with the installation of a levee. This has created a ponded marsh behind the levee that has been subject to degradation relative to the natural remnant saltmarsh in front of the levee. This presentation outlines results from the fish surveys (using fyke and seine nets) and hydrological monitoring (using HOBO water level data loggers) undertaken over a period of three years, representing three stages of restoration: 1) before restoration; 2) with partial levee breaching; 3) will full levee removal. The design of this study is intended to shed light on the benefits of partial and full hydrological restoration to the access and use of the saltmarsh habitat by fish. Findings from this study will help underpin part of the Environmental Economic Accounting (EEA) for fish ‘habitat services’, demonstrating the outcomes of Blue Carbon Ecosystem Restoration of Temperate Saltmarsh, and is funded by the Australian Governments’ Blue Carbon Ecosystem Restoration Grants program.
