Canopy bulk density (CBD) is an important component of wildland fire behavior. CBD remains very difficult to quantify at even the plot level. Estimation at the stand, landscape, and beyond is even more problematic, but CBD remains a necessary input in most fire behavior models. This webinar will present the results of several recent and ongoing studies that examine the use of several forms of Light Detection and Ranging (LiDAR) for improving our ability to estimate this parameter. These studies indicate that, with field-based training data, we can use LiDAR datasets to develop three-dimensional estimates of canopy fuel profiles at relevant horizontal and vertical resolutions. This webinar will also present the results of several case studies where land management and wildland fire histories were used to stratify LiDAR data products to illustrate the effect that these events had on canopy fuel structure.
