[From Objectives and Methods] This project introduces a conceptual scheme, tentatively called 'Canadian Conifer Pyrometrics' (CCP), that combines four separate modelling components into a coherent system for predicting wildfire behaviour in conifer forest fuel types. A simple estimate of surface fire spread was fitted using aggregated observations from the Canadian Forest Fire Behavior (FBP) System database. The Wotton and Beverly (2007) equations for estimating fine fuel moisture content were then used in a reanalysis of the Cruz et al. (2004, 2005) crown fire models. This allowed for stand-sensitive estimates of fuel moisture content and stand-specific crown base height and crown bulk density measures to be linked with the process of crown fire initiation and spread for conifer forests. The result is a fire behaviour modelling system built on empirical data that potentially offers much greater flexibility with respect to conifer fuels than the existing FBP System.
