Full description


A Savanna Super Site (SSS) has been established within Litchfield National Park as part of the Australian Supersite Network (www.tern-supersites.net.au) that is supported by the Terrestrial Ecosystem Research Network (TERN, www.tern.net.au). The SSS is a research and monitoring site representative of high rainfall, frequently burnt tropical savanna. Tropical savanna in Australia occupies 1.9 million km2 across the north and given the extent of this biome, understanding biogeochemical cycles, impacts of fire on sequestration, vegetation and fauna is a national priority.

In the NT, savanna ecosystems are largely intact in terms of tree cover, with only modest levels of land use change. Despite this, there is evidence of a loss of biodiversity, most likely due to shifts in fire regimes and a loss of patchiness in the landscape. Approximately 40% of the savanna burn every year and understanding fire impacts on fauna and flora is essential for effective land management. Vast areas, limited infrastructure and human resources makes the role of remote sensing all the more important for land management in north Australia and this super site aims to address these needs by establishing infrastructure at a significant savanna site of uniform topography within a managed national park (Lichfield NP) that makes it ideal for remote sensing as well as flux studies.

The site will provide nationally consistent observations of vegetation dynamics, faunal biodiversity, micrometeorology (climate, radiation, fluxes of carbon and water), hydrology and biogeochemistry to examine the impacts of fire regime, climate on carbon stocks and GHG emissions, and impacts on habitat quality via ongoing monitoring of vegetation structure and fauna. A wide range of ground based observations of vegetation structure and floristics is planned and all will link to remote sensing of fire and vegetation change over time. Measurements of carbon sequestration and remote sensing properties of vegetation through time will be achieved via the installation of a 40 m guyed tower equipped with instrumentation capable of directly measuring CO2, water use and surface energy properties (energy balance, reflectance). Co-location of Flux observations and remote sensing systems will be co-located to provide TERN with a ground-/air-/space based remote sensing observation stream.

Fire management, both protective and experimental burning regimes will be implemented across the SSS to assess impacts of fire on flora, fauna and biogeochemical cycles in savanna.
