Susquehanna Shale Hills Critical Zone Observatory Tree Survey (2012 updates)

Trees in the Shale Hills watershed were originally surveyed in 2008, with the addition of a sample of tree height data and updated diameter measurements in 2010. Tree survey data includes an assigned tree number with associated data including species, diameter, height (when available), and GPS coordinates. Summary data for the overall watershed is also included in this file. The project was funded by NSF 12-39285.

页岩山流域（Shale Hills Watershed）内的树木首次普查于2008年完成，2010年补充了树木高度数据样本，并更新了树木直径测量数据。本次树木调查数据包含分配的树木编号，以及与之关联的物种信息、直径数据、（可获取时的）高度数据与GPS坐标。本数据集文件同时收录了该全流域的汇总统计数据。本项目由美国国家科学基金会（National Science Foundation，NSF）资助，资助编号为12-39285。
