Overview

NCALM logo

This lidar dataset was collected as part of an NCALM Seed grant for Jean Allen at the University of California, Santa Barbara. This lidar collection was used to quantify Leaf Area Index, and combined with hyperspectral data, quantify the ongoing changes in canopy architecture and oak mortality that has occurred at the Dangermond and Sedgwick Reserves since 2018.
