Seed and Associated Tree Data from Long Term Research Plots in Sequoia and Yosemite national parks

This dataset was used as part of a continent-wide analysis of tree fecundity and its association with climate and tree size. This dataset consists of: plotinfo.csv, which contains basic attribute information for the field plots where the data were collected; seeddata.csv, which contains the data for seeds collected (how many, what type, etc.); trapxycoord.csv, which contains location and identification information for the seed traps used to collect the seeds; treexycoord.csv, which contains location and attribute information for the standing trees in the plot where the seeds were collected; and treedata.csv, which contains data on the size and species of standing trees in the plot where the seeds were collected.本数据集被用于一项全大陆尺度的树木结实量及其与气候、树木尺寸关联性的分析研究。本数据集包含如下文件：plotinfo.csv，内含数据采集野外样地的基础属性信息；seeddata.csv，内含采集所得种子的相关数据（如种子数量、种子类型等）；trapxycoord.csv，内含种子采集所用诱捕器的位置与标识信息；treexycoord.csv，内含种子采集样地内活立木的位置与属性信息；treedata.csv，内含种子采集样地内活立木的尺寸与物种相关数据。
