These data were collected as part of the River Red Gum Ecological Thinning Trial. Data were collected for four tree canopy cover and health parameters, as described below: Foliage Projective Cover (FPC): FPC is a measure of canopy density derived from Landsat images that describes the percentage of ground area occupied by the vertical projection of green foliage of woody vegetation greater than two metres in height. The Landsat satellite provides remotely sensed images at 30 m resolution at 16-day intervals. Mean and median FPC was calculated from multiple pixels (30 m x 30 m) within each 9 ha plot for each date between 2014 to 2022. Canopy Cover: Canopy cover was visually estimated as the foliage projective cover of canopy trees, expressed as a percentage of the area in each subplot. Canopy cover data was collected six times over seven years. These data were collected as part of the floristic structure surveys in three 20 m x 20 m subplots within each 9 ha plot. Tree Crown Size: The crown size of each of the 30 permanently marked trees was measured three times over seven years. Crown size was measured by estimating the distance between the canopy edges in 2 perpendicular planes in metres. Tree Crown Extent: The crown extent of each of the 30 permanently marked trees was measured six times over seven years. Crown extent is defined as the percentage of the potential crown that contains live foliage and was visually estimated to the nearest 5%. Further information is provided in the reference guide for each dataset.
