Tree Seed Data at the Hubbard Brook Experimental Forest, 1993 - present

Seeds Abstract Tree seeds sorted and counted from long-term reference area litter traps are presented for 1993 until the present. These data are part of the LTER funded quantification of tree annual productivity. Our focal species for seed counts have been sugar maple, American beech and white ash. This data set allows comparison between seed production in reference sites (BB and TF) and the calcium addition watershed (W1) for these species.

本数据集呈现了1993年至今，从长期参考区域枯落物收集器（litter traps）中分拣并计数的林木种子数据。本数据隶属于长期生态研究（Long Term Ecological Research, LTER）资助的林木年生产力量化项目。本次种子计数的目标物种为糖枫（sugar maple）、美洲山毛榉（American beech）与白蜡树（white ash）。本数据集可用于对比上述物种在参考样地（BB与TF）以及加钙集水区（W1）的种子产量差异。
