0430 379 817 James.Cleverly@uts.edu.au Leaf area index (LAI) can be defined as the total one sided area of leaf tissue per unit area of ground and is a key derived parameter that is associated with water and light interception, radiation transfer, water and carbon exchange. Canopy cover can be defined as the fraction of ground shaded by the vertical projection of tree crowns. These measures may be used as proxies for actual canopy leaf area. Leaf area index is the preferred measure of cover for vegetation and is a key variable used in total biomass estimation and in carbon cycling prediction models. Indirect measures of LAI include digital photographic methods using flat or hemispherical images, referred to respectively as Digital Cover Photography (DCP) and (Digital Hemispheric Photography (DHP). LAI measurements are carried out at each SuperSite using the most appropriate method for the vegetation type present. Digital Cover Photography (DCP) was carried out at the Alice Mulga SuperSite core 1 ha. 0501 0602 0607 anzsrc-for Alice Mulga SuperSite Core 1 ha Leaf Area Index LAI Digital Canopy Photography Creative Commons Attribution 4.0 International License Alice Mulga SuperSite Core 1 ha 133.25 133.25 -22.28 -22.28 2015 1448485623212

LAI image collection was carried out generally as described in SuperSites Vegetation Monitoring Protocols, Tern Australian SuperSite Network, http://dx.doi.org/10.4227/05/56134C1310F16

LAI Calculation was carried out using two methods: 1) LAI was calculated using DCP software version UTS (modified: Rhys Whitley, Nicolas Boulain) written by Sigfredo Fuentes based on algorithms obtained from MacFarlane et al. 2007. Estimation of leaf area index in eucalypt forest using digital photography. Agricultural and Forest Meteorology 143, 176–188. 2) Images were analysed with DCP-313 software written by Craig Macfarlane (CSIRO) to compute canopy LAI (MacFarlane et al. 2007). A single (blue) channel image is processed to create a grey-scale. Where RAW images are available, contrast stretching of the blue channel is achieved using the RAW2JPG MATLAB script before saving in JPG format prior to analysis (Macfarlane et al., 2014 Digital canopy photography: Exposed and in the raw. Agricultural and Forest Meteorology 197, 244‐253). Both DCP-313 and RAW2JPG executables are available from http://www.tern‐supersites.net.au/index.php/publications‐and‐resources/resources-for-supersiteusers
