Initial Assessment of Canopy Fuel Factors in Forested Areas of the Netherlands
… to estimate fire behavior. Data to estimate canopy bulk density for modelling canopy fire behavior were collected in the Netherlands for Douglas-fir (<em>Pseudotsuga menziesii </em>(Mirb.) Franco), Scots pine<em> </em>(<em>Pinus sylvestris </em>L.), and black pine<em> </em>(<em>Pinus nigra …

Spatio-temporal optimization of tree removal to efficiently minimize crown fire potential
… use indicators of crown fire potential (e.g., canopy base height and canopy bulk density) that ignore variability of fuels within stands, location of individual cut- and leave-trees after treatments, and the temporal effects of these prescriptions for reducing crown fire potential over time. To …

Using Airborne Laser Altimetry to Characterize Surface Fuels in Western Montana
… canopies. Metrics derived from LiDAR include canopy base height, canopy bulk density, biomass, crown height, basal area, and tree stem location. This study focuses on the surface fuel bed, defined as the two meter stratum above ground. The relationships between LiDAR-derived surface roughness …

Overstory structure and detrital dynamics of ponderosa pine forests: insights into fire behavior and its carbon consequences
… showed potential for estimating tree density, canopy base height and canopy bulk density, though more extensive datasets are needed to describe these relationships. These spatially explicit estimates are useful for quantifying carbon stocks and as inputs for fire behavior models. I …

Estimating pre-fire forest structure with stereo imagery and post-fire lidar
… a 2013 post-fire lidar collection. A suite of canopy height and density metrics were created from both the pre-fire photogrammetry and the post-fire lidar point clouds. These metrics were compared to each other and to forest structure attributes measured in the field. For unburned areas, we …
