我们量化了魁北克省圣希莱尔山一片古老的阔叶林中木质生物量和材积的损失，这是一场大冰暴的结果。1998年1月的风暴每公顷带来19.9公吨(风干)或33.6米(3)的木质碎屑。这大约是风暴前这片森林地上总生物量的7%-10%，大约是北美东北部温带落叶林典型的木质凋落物年产量的10-20倍。木质生物量的损失是有记录以来最大的一次冰暴。这场冰暴的影响在任何地方的森林景观中都是最具破坏性的风暴和飓风之一。
We quantified the amount of woody biomass and volume lost in an old-growth hardwood forest at Mont St. Hilaire, Quebec, as a consequence of a major ice storm. The storm of January 1998 brought down 19.9 (air-dried) metric tons or 33.6 m(3) of woody debris per hectare. This is about 7-10% of the total aboveground biomass in this forest before the storm and is about 10-20 times greater than the annual production of woody litter typical for temperate deciduous forests in northeastern North America. The woody biomass lost is the greatest recorded for any ice storm. The impact of this ice storm ranks among that of the most damaging windstorms and hurricanes recorded in forested landscapes anywhere.
