Climate change with its predicted higher incidence of droughts and longer growing seasons is likely to change the nutrient supply and requirements of forests. Silicon (Si), one of the most abundant element in soils, is now considered a nutrient for some species. It has attracted lots of interests lately for its role in mitigating the effects of increasing CO2 concentrations. My recent research indicates that sugar maple and beech, two dominant hardwoods in northeastern America, may be active accumulators of Si. If confirmed, this would suggest that it is required to grow at optimum levels and that researchers have been underestimating its role in these species.

气候变化预计会增加干旱的发生率和延长生长季节，这可能会改变森林的养分供应和需求。硅（Si）是土壤中最丰富的元素之一，现在被认为是某些物种的营养物。最近，它在减轻二氧化碳浓度增加的影响方面的作用吸引了很多人的兴趣。我最近的研究表明，美国东北部的两种主要硬木糖枫和山毛榉可能是硅的活跃蓄积者。如果得到证实，这将表明它需要在最佳水平上生长，研究人员一直低估了它在这些物种中的作用。
