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.

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 their basal or canopy cover was 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) GIS files of the digitized maps in shapefile format; 4) A tabular version of the entire dataset (see "Density and cover of all individual plants" below; this is a table with no spatial information except an x,y coordinate for each individual plant record); 5) A species list, containing information on plant growth forms; 6) Quadrat information, such as grazing information and location in the study site; 7) An inventory of the years each quadrat was sampled; 8) Monthly precipitation; 9) Monthly temperatures.
