Future of Oak Forests experiment - DBH of trees in Black Rock Forest, New York, USA, 2007.

This data set contains the measurement of diameter at breast height (1.4 meters above ground) (dbh) for individual non-oak and oak trees at the Future of Oak Forests (FOF) experiment in Black Rock Forest (Cornwall, NY) during July and August of 2007. The North Slope site contains 12 square-shaped plots, each of 75 meters by 75 meters. Each plot was subdivided into nine equal-sized subplots, each of 25 meters by 25 meters. Within each plot, all individual oak trees with dbh of at least 2.4 centimeters were measured using metric DBH tapes (e.g. Lufkin executive thinline). Within each center subplot of a plot, all individual non-oak trees with dbh of at least 2.4 centimeters were measured using metric DBH tapes (e.g. Lufkin executive thinline). This data can be used to study the individual variation and metabolic scaling of oak and non-oak species in the Forest.

本数据集收录了2007年7月至8月期间，位于纽约州康沃尔市的黑石森林（Black Rock Forest）内的橡树未来实验（Future of Oak Forests, FOF）样地中，非栎类与栎类单株树木的胸径（diameter at breast height, DBH，距地面1.4米处的树干直径）测量数据。该实验的北坡样地共设置12个方形样方，单个样方尺寸为75米×75米。每个样方被均分为9个等大的副样方，每个副样方尺寸为25米×25米。在每个完整样方内，所有胸径不小于2.4厘米的栎类单株树木，均使用公制胸径尺（例如Lufkin executive thinline）完成测量。在每个样方的中心副样方内，所有胸径不小于2.4厘米的非栎类单株树木，同样采用公制胸径尺（例如Lufkin executive thinline）进行测量。本数据集可用于研究该森林内栎类与非栎类物种的个体变异及代谢缩放规律。
