Evaluation of snag density and snag metrics in Old Growth Deferral Priority Areas in the Cariboo region using airborne LiDAR data Ong, Robin Zuo Feng
Description
Standing dead trees (snags) are crucial habitats for fauna in mature and diverse forests along the Interior Douglas-fir Zone of British Columbia. The objective of this study is to evaluate whether snag density and snag metrics differ between three categories of at-risk and irreplaceable Old Growth Priority Deferral Areas (ancient, big-treed and remnant) and their neighbouring areas with no deferral status. Using airborne LiDAR data, we detect snags using 1) area-based forest metrics paired with random forest modelling, and 2) an individual snag detection algorithm.
