Forest Inventory of a Whole Tree Harvest: Hubbard Brook Experimental Forest Watershed 5, 1982, pre-harvest

A whole-tree harvest was conducted during the dormant season of 1983-1984 in order to assess ecosystem response to whole-tree logging operations. Pre-harvest forest inventory surveys were conducted in 1982 on the whole of the watershed and are presented in this dataset. Full post-harvest surveys were conducted in 1990, 1994 and every 5 years thereafter. Survey methods differed between years due to the variability encountered in the aggrading forest. 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.1983-1984年的休眠季，研究团队开展了全树收获实验，旨在评估全树采伐作业对生态系统的响应。1982年，研究人员对整个集水区完成了采伐前森林清查，相关清查数据已收录于本数据集。后续分别于1990年、1994年开展全面的采伐后清查，此后每5年进行一次清查。由于正向演替森林中存在的环境异质性，不同年份所采用的清查方法存在差异。本数据集的采集工作隶属于哈伯布鲁克生态系统研究（Hubbard Brook Ecosystem Study, HBES）项目。该项目依托由美国农业部林务局（USDA Forest Service）北方研究站运营维护的哈伯布鲁克实验林开展，为跨机构合作研究项目。
