Phenology of California Grasslands,By comparison with many other plant com-munities, the annual grasslands of California are considered phenologically simple and relatively uniform. Both within and among different grasslands, the relationship between climate and plant growth and development follows a repeated pattern:

Accordingly, I have adopted a chronological format in reviewing the available information.
