Canopy closure is a forest metric derived from Lidar point clouds. This metric measures the canopy closure of a given horizontal cell above a given vertical threshold (height break). Canopy closure can inform many landscape models and provide insight on how much light will reach the forest floor.
The canopy closure is derived from the raw Lidar point clouds using the FUSION software. The horizontal resolution is 5 meters and the height threshold is 2 meters. All Lidar returns were used so that sub canopy vegetation would have an effect on the result. Canopy closure is defined as the number of returns over a specified height threshold divided by the total number of returns within each cell.
Watershed Sciences, Inc. (WS) collected Light Detection and Ranging (LiDAR) data from HJ Andrews and the Willamette National Forest (NF) on August 10th and 11th 2008. Total area for this AOI is 17,705 acres. The total area of delivered LiDAR including 100 m buffer is 19,493 acres.
