During the ground surveys, aerial surveys were also conducted. Atotal of 3,382 photos were taken over the <strong>Rimba</strong> <strong>Raya</strong>concession. Photos with high cloud cover were excluded andremaining photos were ortho-­‐rectified and georeferenced asdescribed in the baseline report. One-­‐hectare plots wereinstalled in the center of each photo and tree crowns wereidentified and measured in order to estimate above ground treebiomass. Example aerial photos with plots and tree-­‐crowndelineations are shown below for lightly degraded peat swampforest (Figure 12a) and kerangas forest/open scrub (Figure 12b).Biomass by landcover class for <strong>Rimba</strong> <strong>Raya</strong> based on ground andaerial survey analysis is shown in Table 3.Land Cover DescriptionTable 3.
