DescriptionThe physical properties and dimensions of foliage are necessary inputs for some fire spread models. Currently, almost no data exist on these plant characteristics to fill this need. In this report, we measured the physical properties and dimensions of the foliage from 10 live shrub and conifer fuels throughout a 1-year period. We developed models to predict relative moisture content, apparent density, length, width, needle length, thickness, stem diameter, and surface area. Seasonal variability of the response variables was found to be adequately explained with a single model, so season-specific models or models with a seasonal parameter were unnecessary.
