Mapped plant community time series, Dubois, ID, 1923-1973

This historical dataset consists of a series of permanent 1-m^2 quadrats located on the sagebrush steppe in eastern Idaho, USA. The key aspect of the data is that during each growing season, all individual plants in each quadrat were identified and mapped. The combination of a long time-series with full spatial detail allows analyses of demographic processes and intra- and interspecific interactions among individual plants. This distribution contains the following data and data formats: 1) image files (*.tif) of the original, scanned maps; 2) the digitized maps in shapefile format; 3) a tabular version of the entire dataset (a table with no spatial information except an x,y coordinate for each individual plant record); 4) a species list, containing information on plant growth forms and shapefile geometry type; 5) quadrat information, such as grazing information and original quadrat names (the names as they appear in the original, scanned maps); 6) an inventory of the years each quadrat was sampled; 7) monthly precipitation, temperature, and snowfall records; and 8) counts of annuals in the quadrats.本历史数据集包含一系列永久性1平方米样方（quadrat），布设在美国爱达荷州东部的蒿类干草原上。该数据集的核心特征在于，每个生长季期间，研究人员都会对每个样方内的所有单株植物进行物种鉴定与空间定位绘图。长时序数据与完整空间细节的结合，支持针对单株植物的种群动态过程、种内及种间相互作用开展分析。本数据集分发包包含以下数据及对应格式：1）原始扫描绘图的影像文件（格式为*.tif）；2）采用形状文件（shapefile）格式存储的数字化绘图文件；3）全数据集的表格版本（该表格仅包含单株植物记录的x、y坐标，无其他空间信息）；4）物种名录，包含植物生长型及形状文件几何类型相关信息；5）样方信息，涵盖放牧记录及原始样方名称（即原始扫描绘图中所使用的名称）；6）各样方的采样年份清单；7）月降水量、气温及降雪量记录；8）各样方内一年生植物的数量统计。
