摘要: Critical to the understanding of impact mountain pine beetle infestation in British Columbia is ability determine volume lodgepole killed across large areas. A methodology using digital aerial imagery and lidar data estimate affected presented. After employing image interpretation species composition, DBH (diameter at breast height), severity attack, measure stand height, species-specific equations were used volumes killed. Results indicate that total estimates generally agree with available forest inventory data. Volumes lost attack ranged from 0 400 m/ha, an overall mean standard deviation 159 109 respectively. This working paper presents initial results work published Bater et al (in press).
