Abstract

The ability to rapidly acquire biometric data in forests allows for timely decisions to be made regarding harvest, fertilization, prescribed fire, or other silvicultural treatments. High resolution tree-level data can be used to assess tree conditions and in calculating tree- or stand-level volume estimates. Using mobile, terrestrial light detection and ranging (LiDAR) units, such data collection is possible and provides an archive of present stand conditions. This study seeks to apply a mobile backpack LiDAR unit to a 3-year-old planted stand in northern Louisiana. The objective of the present study is to compare LiDAR-derived measurements with in situ measurements for height and groundline diameter.
