White Spruce NPP: Tree density and basal area by diameter sizeclass in upland and floodplain mid- and late-successional stands: 1989-2008

This data set is derived from BNZ LTER inventory plots. Stand density and basal area are listed by diameter size class of live white spruce trees for each replicate stand within mid-successional and mature white spruce stands within both floodplain and upland landscapes by year from 1989-2008.

本数据集源自BNZ长期生态研究（BNZ LTER）的调查样地。数据集涵盖1989年至2008年各年份的观测数据，针对河漫滩与高地两类景观下的中演替阶段白云杉林分及成熟白云杉林分，分别统计了各重复样地内活立白云杉按径级划分的林分密度与胸高断面积。
