High quality digital images are captured using a digital SLR camera at the plots (core 1 hectare vegetation plot) at the TERN Gingin Banksia Woodland SuperSite using the panoramic photopoint method. The panoramic photopoint method may be the most informative in open forests/woodlands and rangelands. Three photopoints are established configured in an equilateral triangle (2.5m sides) with the centre marked with a star dropper and the location recorded with DGPS. At each photopoint take photographic sequences in a 360° panorama, with up to 40 photographs with a minimum 50% overlap between consecutive photographs. For more information about the method, see
White, el al. (2012) AusPlots Rangelands Survey Protocols Manual Version 1.2.9. TERN’s Gingin Banksia Woodland SuperSite is on the Swan Coastal Plain, approximately 10 km southwest of Gingin and 80km north of Perth, Western Australia. The site sits in a natural woodland of high species diversity (overstorey dominated by Banksia spp) that overlays the Gnangara groundwater mound, Perth’s most important groundwater resource. The site is 2 km from the University of Western Australia International Gravity Wave Observatory. The traditional owners at Gingin are the Yued group of the Noongar People. For additional site information, see

Other images collected at the site include digital cover photography, phenocam time-lapse images taken from fixed under and overstorey cameras, five-photopoint images and ancillary images of fauna and flora.
Credit
We at TERN acknowledge the Traditional Owners and Custodians throughout Australia, New Zealand and all nations. We honour their profound connections to land, water, biodiversity and culture and pay our respects to their Elders past, present and emerging.
The Gingin Banksia Woodland Site is funded by TERN. It was established by CSIRO and is currently managed by the Edith Cowan University (Centre for Ecosystem Management). The site is co-located with the Land Ecosystem Atmosphere Program (LEAP) – Gingin.
Purpose
The images are to be used where possible to supply images for analysis that produces 3D reconstructions to monitor change over time and provide an estimate of basal area and biomass.
