Seed and Associated Tree Data from Long Term Research Plots in Sequoia and Yosemite National Parks (ver. 2.0, December 2024)

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.

本数据集被应用于一项全大洲范围的树木繁殖力 (tree fecundity)及其与气候、树木体量关联关系的分析研究。
该数据集包含如下文件：plotinfo.csv，存储了数据采集所用野外样地 (field plots)的基础属性信息；seeddata.csv，存储了所采集种子的相关数据（含采集数量、种子类型等内容）；trapxycoord.csv，存储了用于种子采集的种子诱捕器 (seed traps)的位置与标识信息；treexycoord.csv，存储了种子采集样地内活立木 (standing trees)的位置与属性信息；treedata.csv，存储了该样地内活立木的体量与物种相关数据。
