Digital Hemispherical Photography (DHP) upward-looking images to capture vegetation and crown cover are collected two times per year in a 20 m grid within the core hectare plot at the Alice Mulga SuperSite. These images are used to estimate Leaf Area Index (LAI).

The Alice Springs Mulga flux station is located on Pine Hill cattle station, approx. 170km north of Alice Springs in the Northern Territory. The woodland is characterised by a mixed Acacia aneura and Acacia aptanura canopy, with a total standing biomass of 32.5 t/ha and median canopy height of 4.3 m (tallest trees reach 8.9 m height). Elevation of the site is 602 m above sea level, and the terrain is flat. Mean annual precipitation at the nearby (45 km distant) Bureau of Meteorology station is 311 mm - 140 mm (1986-2025), but has ranged between 33 mm in the hydrological years of 2018/2019 to 712 mm in 2016/2017 since the tower is operational. Predominant wind directions are from the southeast and east. The extent of the woodland is 11 km to the east of the flux station and 16 km to the south. The soil is characterised as a red kandosol (74:11:15 sand:silt:clay) overlying an approx. 50 m deep water table. Pine Hill Station is a functioning cattle station that has been in operation for longer than 50 years. For additional site information, see Alice Mulga Supersite.

Other images collected at the site include photopoints, phenocam time-lapse images taken from fixed under and overstorey cameras and ancillary images of fauna and flora.
