2019 Bellamy River Reservoir Vegetation Plot Raw Datasheets & Cover Calculations

The pdf file contains scans of vegetation plot raw datasheets for eight vegetation plots placed throughout the Bellamy River Reservoir in Dover, NH, USA. Field botanists (Dr. Brett Still and trained graduate students) from University of Rhode Island visited the site on August 20, 2019 to collect vegetation data following the Stream Barrier Removal Monitoring Guide (Collins et al. 2007), which organizes vegetation structure into three cover classes partly defined by vegetation height. Herbaceous cover was defined as vegetation less than 0.9 m (3 ft) in height, shrub cover was 0.9 m (3 ft) to 6.1 m (20 ft), and tree cover was >6.1 m (20 ft). Herbaceous plants were evaluated within a 5 ft radius from a vegetation plot center, shrub plants within a 15 ft radius, and tree cover within a 30 ft radius. Vegetation species data as well as vegetation structure data were collected at the vegetation plots. An illustrative percent cover guide (e.g. Terry & Chilingar 1955) was used in the field to help reduce the subjectivity in estimating percent cover for each plant species in the field. The included spreadsheet contains the calculations used for determining vegetation cover in each plot. These data were collected using resources from an NSF EPSCoR funded project “RII Track-2 FEC: Strengthening the scientific basis for decision-making about dams: Multi-scale, coupled-systems research on ecological, social, and economic trade-offs” (a.k.a. "Future of Dams"). Support for this project is provided by the National Science Foundation’s Research Infrastructure Improvement NSF #IIA-1539071.

本PDF文件包含美国新罕布什尔州多佛市贝拉米河水库全域布设的8个植被样地（vegetation plot）的原始记录表扫描件。罗德岛大学的野外植物学家（布雷特·斯蒂尔博士与经过培训的研究生）于2019年8月20日到访该样地，依据《溪流屏障移除监测指南》（Collins等人，2007年）开展植被数据采集工作；该指南将植被结构按植被高度划分为3个盖度等级（cover classes）。其中，草本层盖度（herbaceous cover）指高度低于0.9米（3英尺）的植被，灌木层盖度（shrub cover）指高度介于0.9米（3英尺）至6.1米（20英尺）的植被，乔木层盖度（tree cover）指高度高于6.1米（20英尺）的植被。植被调查时，草本植物的调查范围为样地中心半径5英尺区域内，灌木植物为半径15英尺区域内，乔木盖度则在半径30英尺区域内进行评估。本次植被样地调查采集了植物物种数据与植被结构数据。野外调查期间，参考了盖度百分比（percent cover）示例指南（如Terry与Chilingar，1955年）以降低现场估算各植物物种盖度时的主观性。随附的电子表格（spreadsheet）包含用于计算各植被样地盖度的相关公式与步骤。本数据集依托美国国家科学基金会（National Science Foundation, NSF）EPSCoR资助项目“RII Track-2 FEC：强化大坝决策的科学基础——生态、社会与经济权衡的多尺度耦合系统研究”（亦称“大坝的未来”）的相关资源完成采集。该项目由美国国家科学基金会研究基础设施改进项目（资助编号：NSF #IIA-1539071）提供支持。本材料中表达的任何观点、发现、结论或建议仅代表作者本人，并不一定反映美国国家科学基金会的官方立场。
