A growing concern associated with fire in The Netherlands is estimating the spread of wildfire, however often the data needed to estimate canopy fires are lacking. The primary parameter required is canopy bulk density (CBD), which requires estimations of canopy gap fraction and leaf area index (LAI). The accuracy of three indirect methods of estimating CBD (a densiometer, hemispherical canopy photographs (HCP), and a LI-COR LAI 2200c plant canopy analyzer) was compared for three common tree species in the Netherlands [Scots pine (Pinus sylvestris L.), black pine (Pinus nigra Arnold) and Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco)]. No …
