Executive Summary

The Kakadu National Park Ramsar site is listed as a Wetland of International Importance under the “Convention on Wetlands of International Importance especially as Waterfowl Habitat” or, as it is more commonly referred to, the Ramsar Convention (the Convention).

This report provides the Ecological Character Description (ECD) for the Kakadu National Park Ramsar site, and has been prepared in accordance with the National Framework and Guidance for Describing the Ecological Character of Australia’s Ramsar Wetlands (DEWHA 2008). This is the first ECD prepared for the site. In parallel with the preparation of the ECD, the Ramsar Information Sheet (RIS) for the site has been updated for submission to the Australian Government and Ramsar Secretariat.

The Kakadu National Park Ramsar site is located approximately 200 kilometres east of Darwin in the Northern Territory. The Kakadu National Park Ramsar site was historically two separate Ramsar sites within Kakadu National Park. These were Kakadu National Park (Stage I including wetland components of Stage III) and Kakadu National Park (Stage II). Kakadu National Park Stage I was originally listed as a Ramsar site in 1980 and expanded in 1995 to include wetland components of Stage III, while Stage II was listed in 1989 as a separate Ramsar site. The separate listing under the Stages reflected the historical listing of the area as a World Heritage site and a national park.

The Kakadu National Park (Stage I including wetland components of Stage III) Ramsar site comprised of all lands and waters in the eastern portion of the Kakadu National Park, following the eastern boundary of the Park along the East Alligator River and including the Nourlangie, Jim Jim and Barramundi Creeks. In 1995, the boundaries of site number two were extended to include only the wetland habitats within the eastern and southern areas of Kakadu National Park (Stage III).

Kakadu National Park (Stage II) Ramsar site encompassed all lands and waters situated in the northern and western part of the National Park, including the Wildman, West Alligator and South Alligator River systems and their floodplains, following the western Kakadu National Park boundary. The Stage II area also included both Field Island and Barron Island within Van Diemen Gulf to the low water mark.

In April 2010, the two Ramsar sites were merged together to form a single Ramsar site, called Kakadu National Park. In addition, the site was extended by approximately 600 000 hectares to include all remaining areas of Stage III. The merger and extension bought the Ramsar boundary in line with the existing boundary of the national park.

Ecological Character Descriptions describe the ecological character of a wetland at the time of its listing as a Wetland of International Importance. Although Kakadu National Park is now a single Ramsar site, it is important to report baseline data that reflects the different listing dates of the three Stages.

The Ramsar site is bounded by the following geographic features:

  • Van Diemen Gulf and the Timor Sea in the north

  • the East Alligator River and Arnhem Land in the east

  • Wildman and Mary River catchments in the west, and

  • Arnhem Land plateau to the south.

Approximately 50 percent of Kakadu National Park is Aboriginal land under the Aboriginal Land Rights (Northern Territory) Act 1976. Most of the remaining area of land is under claim by Aboriginal people. Title to Aboriginal land in the Park is held by Aboriginal Land Trusts that have leased their land to the Director of National Parks (under the Environment Protection and Biodiversity Conservation Act 1999) for the purpose of being managed as a Commonwealth Reserve. Land in the Park that is not Aboriginal land is vested in the Director.

The Kakadu National Park Ramsar site is composed of a diversity of coastal and inland wetland types. Wetland types present range from intertidal forested wetlands and mudflats, to seasonal freshwater marshes and permanent freshwater pools. Using the Ramsar typology, there are five coastal types and eight inland types within the Stage I and Stage III area. Within the Stage II area, there are nine coastal types and seven inland types.

The ECD has reviewed the Ramsar Nomination Criteria under which the two original Ramsar sites were listed as Wetlands of International Importance, and examined the applicability of the revised and new Criteria under the Convention that have been added since the sites were originally listed in 1980 and 1989. In this context, Kakadu National Park is now seen as meeting all nine Nomination Criteria of the Convention, recognising the representative wetland habitats of the site at a bioregional level, support of populations of vulnerable wetland species, its characteristics as a centre of endemism and high biodiversity including its diversity of habitats, support for key life-cycle functions such as waterbird breeding and refugia values, its importance for supporting substantial populations of waterbirds and fish diversity and fish nursery and spawning habitats and its support of at least one percent of the national population of several non-avian wetland species.

Critical components of the Ramsar site include key wetland habitats and populations of waterbirds, freshwater fish, aquatic invertebrates, turtle and crocodiles. The critical ecosystem processes that underpin the habitats of the Kakadu National Park Ramsar site include hydrology, fire regimes and notable biological processes, with supporting processes including climate, tidal hydraulics, groundwater, water quality, geology and geomorphology.

The wetland components and processes of the site support a broad range of ecosystem services/benefits including support of threatened fauna, support of endemic species, fisheries resource values and contemporary living culture. Additionally, cultural and socio-economic services are equally diverse, noting the particular importance of the wetlands of the site to the traditional owners and caretakers of Kakadu National Park (the ‘Bininj’), as well as tourism and recreational values.

A summary of the critical services/benefits provided by the Kakadu National Park Ramsar site and the underlying critical ecosystem components and processes nominated by this ECD is given in Table E-1. The critical wetland services/benefits nominated were based on the attributes of the site described in the Ramsar Nomination Criteria as well as identifying critical ‘cultural’ services/benefits provided by the site in terms of human use. The critical wetland components and processes have been selected based on the particular characteristics of Kakadu National Park and on the basis that they underpin the critical services/benefits, but may also be critical in their own right.

As required by the National Framework document, the study has:

  • sought to define the natural variability and limits of acceptable change (LACs) for the critical components, processes and services/benefits identified

  • examined ecological character changes that have been observed or documented since listing of the sites in 1980 and 1989 (including assessment against relevant LACs), and

  • investigated current and future threats to ecological character.

While the level of quantitative information and data needed to provide a more definitive assessment of ecological character change (and to set more definitive LACs as sought by the National Framework) are not available, it would appear unlikely that any of the LACs presented in the ECD have been meaningfully exceeded. It is noted however that saltwater intrusion processes have possibly degraded freshwater billabongs and other palustrine wetlands and Melaleuca communities.

The effect of saltwater intrusion in the floodplain areas of the Park has had the effect of changing the spatial characteristics and distribution of tidal creeks and associated mangrove environments over a long time period, often at the expense of predominantly freshwater systems. This includes the loss of several freshwater billabong environments located proximal to the tidal channels and at the fresh-salt interface areas of the major river systems, noting that these features have both ecological and cultural significance in terms of traditional food sources and traditional customary usage. However, the extent to which saltwater intrusion represents an ecological character change is difficult to assess noting that saltwater intrusion into Kakadu National Park’s freshwater wetlands is a continuous natural process. A key factor to be considered is whether the environmental change or the rate of change can be perceived as having an anthropogenic source.

Recent or continuing threats that are notable in the context of the site that may affect future ecological character include:

  • introduction and/or proliferation of exotic flora and fauna

  • climate change

  • tourism and recreational activities (including boating)

  • mining activities

  • damage to archaeological resources and rock art, and

  • living resource extraction.

Of these threats, future impacts from climate change in terms of increased saltwater intrusion and impacts from the continuing persistence and spread of cane toads are seen as the most likely and potentially severe.

Information gaps, monitoring needs and recommendations in relation to communication, education, participation and awareness messages are also identified in the ECD. Key information gaps in the context of this ECD require:

  • additional research and monitoring to establish an ecological character baseline for the key habitats

  • better information and data sets about the presence and natural history of critical wetland species and their habitats including for example, surveys of threatened plant species, aquatic fauna species such as the river shark species and more systematic surveys of important avifauna and fish species and populations

  • better information and understanding about the natural variability of wetland fauna populations and key attributes and controls on those populations

  • additional investigation of the ecological character thresholds of particular habitats and communities to changes in key attributes/controls such as hydrology. The LACs stated in the ECD should be reviewed and revised as improved information becomes available, and

  • more specific assessment of the vulnerability of the site to the impacts of climate change, and adaptation options that could be explored to reduce the future impacts.

In accordance with the above, monitoring needs and recommendations presented in this ECD relate broadly to obtaining data to assess future changes to ecological character as defined by the critical components, processes and services/benefits associated LACs for the site. Since the monitoring needs are quite extensive, a broad scale ecosystem health-based monitoring program may be most appropriate for the Ramsar site using lessons learned from similar approaches elsewhere. Emphasis should be placed on the collection of data and information about critical and supporting process indicators, such as water quality and biotic indicators of ecosystem health.

A combined set of communication, education, participation and awareness messages relevant to the ECD have been presented and can be used to communicate the importance of the site, why it was listed, possible changes to ecological character, the threats to the site and future actions required. These messages also serve as a summary of the key findings and conclusions of the ECD study.
