Stem counts and seeds measurements in California grassland communities

These data were collected in the field and include initial abundance in grams and seed number, stem counts, and seed counts for each species. Data are arranged such that each row represents a plot and block combination with each species within the plot arranged in columns. The columns are arranged by species with the genus as the first part of the column header followed by the data describer (Avena=Avena fatua, Bromus=Bromus hordeaceus, Brassica=Brassica nigra, Erodium=Erodium cicutarium, Eschscholzia=Eschscholzia californica, Lasthenia=Lasthenia californica, Lotus=Lotus purshianus, Lupinus=Lupinus succulentus, Melilotus=Melilotus indicus, Vicia=Vicia villosa). For each species, the columns are arranged in the same order: "genus name initial (g)" is the initial abundance of the species in grams that were added to the plots; "genus name seeds initial" is the initial number of seeds for each species that were added to the plots; "genus name stems final" is the number of individuals of that species at the end of the growing season in the plot; "genus name seeds final" is the number of seeds of that species at the end of the growing season in the plot
