Fine Litterfall Data at the Hubbard Brook Experimental Forest, 1992 - ongoing

Fine litterfall (leaves, twigs, fruits, seeds, etc.) is collected in Watershed 1, Watershed 5, the Throughfall plots and the Bear Brook Watershed reference forest, located to the west of Watershed 6, to quantify carbon and nutrient flux associated with this important pathway. These measurements have facilitated quantification of ice storm effects and species declines (paper birch, sugar maple). These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.

细枯落物（叶片、细枝、果实、种子等）的采样工作于第1集水区、第5集水区、穿透雨监测样地以及位于第6集水区西侧的布鲁克溪流域对照林内开展，旨在量化该重要物质循环路径对应的碳与养分通量。本测量工作为冰暴影响及纸桦、糖枫的物种衰退的量化研究提供了支撑。本数据集作为哈伯布鲁克生态系统研究（Hubbard Brook Ecosystem Study, HBES）的组成部分收集所得。哈伯布鲁克生态系统研究是依托哈伯布鲁克实验林开展的协作项目，该实验林由美国农业部林务局（USDA Forest Service）北方研究站运营维护。
