Birch NPP: Tree density and basal area by diameter sizeclass in upland and flooplain 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 Alaskan paper birch trees for each replicate stand within mid- and late- successional upland upland and landscapes by year from 1989-2008.

本数据集源自BNZ长期生态研究（Long-Term Ecological Research, LTER）调查样地，按径级统计了1989至2008年间，中、晚演替阶段高地景观内各重复林分中活立阿拉斯加纸桦的林分密度与胸高断面积。
