ENBIOCAL is an application based on sampling theory to estimate the biomass content for bioenergy production in short-rotation plantations of hybrid poplars and willows or abandoned forest lands. For hybrid poplars or willows, users can choose two sampling methods: simple random sampling or stratified random sampling. Allometric equations were developed for 11 hybrid poplar clones and 7 willow species to compute biomass at the plant level. Then, the application computes the number of plant measurements required (sample size) for a given precision level. Once the sample size is determined, ENBIOCAL guides the users for field measurements and provides estimates of biomass content. The application and user-guide can be downloaded from ftp.cfl.forestry.ca/publique/ENBIOCAL.
