Kakadu National Park is renowned world-wide for its iconic landscape, composed of a diversity of wetland types ranging from intertidal mangrove forests and mudflats, to permanent billabongs and vast expanses of seasonal freshwater marshes.
The Stage I Kakadu Ramsar site was listed as one of the first Australian wetlands of international importance under the Ramsar Convention. Later, the Stage II Kakadu Ramsar site was nominated, resulting in a total of 683 000 ha.
BMT was commissioned to conduct an Ecological Character Description (ECD) of the Kakadu Ramsar sites.
Outcomes and Benefits
The study primarily involved an assessment to identify critical processes, components and services of the wetland ecosystems. This assessment relied on input from individuals with extensive experience with the Ramsar sites. A consultation component of the study was conducted in Jabiru. As part of this process, significant threats to the wetland services were identified, information gaps highlighted and conceptual models of ecosystem functions developed.
Quantitative and semi-quantitative limits of acceptable change to critical wetland habitats and species will also develop as part of the study. These limits of acceptable change will need to be assessed in the context of future activities that may affect the ecological character of the wetland as a matter of national environmental significance.
Services and Expertise Provided:
BMT, in association with Buckley Vann town planners and the Department of Civil Engineering at the University of Queensland (UQ), undertook a climate change vulnerability and adaptation planning study for the remote centre of Choiseul Bay, at the northern tip of the Solomon Islands.
The Gold Coast waterways network consists of a range of maritime assets including boat ramps, channels, and anchorages that need to be maintained so that they remain clean, safe and accessible now and into the future.
BMT was engaged by the Department of Industry on behalf of the Marine Estate Management Authority (MEMA) to provide strategic risk assessment advice for the TARA process for a pilot project for the Hawkesbury Marine Shelf Bioregion and then for the State-wide marine estate.
