Rhododendron maximum cover across an elevation gradient from the Coweeta Hydrologic Laboratory from 1997 to 1999

Rhododendron maximum leaf area was measured at 167 locations to determine the spatial extent of this understory shrub, and compare Rhododendron maximum cover with seedling germination rates and seedling diversity (measured in another study). Rhododendron maximum leaf area index was determined at 167 points within each permanent vegetation plot. The initial 86 points were sampled in 1997, and the remainder sampled in the summer of 1999.

本研究在167个样点处测定了北美大叶杜鹃（Rhododendron maximum）的叶面积，以期明确该林下灌木的空间分布范围，并将其盖度与另一项研究中测得的幼苗萌发率及幼苗多样性进行对比。研究人员同时在每个永久性植被样地内的167个测点处测定了北美大叶杜鹃的叶面积指数。首批86个测点于1997年完成采样，剩余测点则于1999年夏季完成采样。
