- Abstract
-
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 was carried out at the South East Queensland Peri-urban SuperSite, Samford, Core 1 ha plot on Jan 19, 31 May, 23 Aug, 15 Nov 2016. Leaf Area Index images are available for viewing and download from the TERN SuperSites BioImage Portal http://bioimages.supersites.net.au/data/photopoint/seqp_samford/default
