The tallest trees were located with the use of the 1m resolution vegetation height raster provided by Watershed Sciences.

Cover metrics were created with the Fusion COVER command. These cover maps were created using all returns. Canopy closure is defined as the number of returns over a specified height threshold divided by the total number of returns within each cell. Map groups below are for the indicated horizontal resolution and contain multiple maps at different vertical thresholds.

Height metrics were created with the Fusion GRIDMETRICS command. These height maps were created using only first returns (top of canopy). Descriptive statistics are computed by raster cell, and each page of the map group indicates the statistic that was generated. Mean height of elevations >2m means that all lidar returns under 2m are ignored. Statistics at 1m horizontal resolution were not computed because many cells did not have enough points to generate output.
