Upscaling individual-based loading allometries


Shrubs are a major component ofsurface fuels in many fire-prone ecosystems. Shrub fuel loading is often estimated by “double sampling”, where data from a destructive vegetation survey is used to model vegetation-fuel relationships (development phase), and these relationships are then applied to vegetation data from a second survey (application phase). Vegetation-fuel relationships can be modeled at different levels ofvegetation detail, from individual plants to stands, but the increased effort of detailed measurements may compromise large-scale applications.To facilitate fuel loading assessments in Mediterranean shrublands, we present and test a novel method to estimate stand- level shrub loading that consists in applying individual-level allometric equations to vegetation plot data collected by measuring the percent cover and mean height of each shrub species.
