Site name: Fowlers Gap Arid Zone Research Station
Site number: 24
Point numbers: 93 (FOWLERS GAP Dry A), 94 (FOWLERS GAP Wet A), 95 (FOWLERS GAP Dry B), 96 (FOWLERS GAP Wet B)
Ecoregion: Deserts and xeric shrublands
Participant and site owner: University of New South Wales, Fowlers Gap Arid Zone Research Station
Site location: Western New South Wales
Latitude: -31.09
Longitude: 141.71
Site description: Fowlers Gap Arid Zone Research Station is located in western New South Wales, about 110 km to the north of Broken Hill. The research station of around 39,000 hectares straddles the Barrier Range and has an arid climate with <250 mm rainfall annually. The Research Station has been established for over 50 years (since 1966) and been the site of long-term research projects focused on kangaroos, arid zone vegetation and birds (particularly the Zebra Finch and Chestnut-crowned Babbler). The barrier ranges are composed largely of sandstone, while the flat country on the eastern side of the research station is scalded flats of loamy sands and clays (site A is in the former and site B in the latter country). Chenopod shrubs dominate in both areas, including Saltbush (Atriplex sp.), Blue Bush (Maireana sp.), and Copperburrs (Sclerolaena sp.). In the flat country major river channels are dominated by River Red Gum (Eucalyptus camaldulensis), with minor drainage lines holding stands of Prickly Wattle (Acacia victoriae) and Dead Finish (Acacia tetragonophylla).

The classic pattern of arid zone ecology, with primary productivity determined by unpredictable rains (both spatially and temporally) make Fowlers Gap an ideal location for long-term ecoacoustic monitoring, with dramatic changes in both the abundance and community structure of animals and plants across years.

Calperum Mallee TERN SuperSite (56)

Access Site 56 data on A2O data portal.

Site name: Calperum Mallee TERN SuperSite
Site number: 56
Point numbers: 221 (Calperum Dry A), 222 (Calperum Wet A), 223 (Calperum Dry B), 224 (Calperum Wet B)
Ecoregion: Deserts and xeric shrublands
Participant and site owner: The University of Adelaide, Terrestrial Ecosystem Research Network
Site location: River Murray floodplains on Calperum Station, near Renmark South Australia
Latitude: -29.383
Longitude: 140.728
Site description: The Calperum Mallee TERN SuperSite is in the mallee semi-arid ecosystem, fringing the River Murray floodplains on Calperum Station, near Renmark South Australia. The area comprises undulating mallee woodlands and riverine vegetation that fringes the River. All areas are in the process of recovering from extensive grazing.

The Calperum Mallee TERN SuperSite has established and reinforced research infrastructure that can measure and monitor the condition of a nationally iconic region. This SuperSite is part of the Australian Flux Network Project and will build on and strengthen existing ecosystem monitoring, grazing and floodplain restoration experiments and link with in-stream water quantity and quality measurements and is an OzFlux energy, carbon and water monitoring site.

The SuperSite is investigating fluxes of water vapour and carbon dioxide between the atmosphere, upper soil layers and groundwater as well as monitoring the changes in vegetation and dependent biota associated with the different ecosystems of the site.

Site name: Alice Mulga TERN SuperSite
Site number: 54
Point numbers: 213 (Alice Dry A), 214 ( Alice Wet A), 215 ( Alice Dry B), 216 ( Alice Wet B)
Ecoregion: Deserts and xeric shrublands
Participant and site owner: University of Technology Sydney, CSIRO, Terrestrial Ecosystem Research Network
Site location: Pine Hill Cattle Station, Northern Territory
Latitude: -22.300
Longitude: 133.200
Site description: The Alice Mulga SuperSite is located on Pine Hill Cattle Station approximately 200 km north of Alice Springs, Northern Territory. It lies in the expansive arid and semi-arid portion of mainland Australia that receives less than 500 mm of annual rainfall. The site includes Mulga woodland, hummock grassland, and River Red Gum forest. The SuperSite Core 1 ha is located in a dense Mulga woodland (cover 70–80%).
