Tree Seedlings in CRUI Land Use Project at Harvard Forest 1996

Forests recovering from agricultural legacies differ in many ways that influence tree seed dispersal and seedling establishment patterns. We recorded the number of seedlings (less than 0.5 m tall) of all tree species on a 1 x 1 m resolution across six land use legacy sites (2 plowed, 2 pastured, 2 permanent woodlot) in summer 1996 to test several predictions about seedling abundance, diversity, and dispersion patterns, and their relationships to forest structure, microclimates, and soil resources.

受农业活动遗留效应影响而恢复的森林，其诸多特征会对树木种子传播及幼苗定植模式产生影响。本研究于1996年夏季，在6处土地利用遗留样地（其中2处为翻耕样地、2处为放牧样地、2处为永久小片林地）中，以1米×1米的空间分辨率统计了所有乔木物种的幼苗（株高小于0.5米）数量，旨在检验关于幼苗丰度、多样性及分布格局，及其与森林结构、微气候和土壤资源之间关联的多项预测。
