Fertility Element Storage in Chaparral Vegetation, Leaf Litter, and Soil1

2 Assoc. Prof. of Forestry, University of California, Berkeley. Abstract: This study was conducted on various chaparral sites sampled throughout California in the range of the following species: chamise, Adenostoma fasiculatum; scruboak, Quercus dumosa; and Ceanothus cuneatus, & C. crassifolius. Data for elemental composition, total vegetation and leaf litter weights, and elemental storage weights for each of these species were determined. These data are aggregated and presented as tables of cumulative probability values for composition and storage weight of nitrogen, phosphorus, calcium, magnesium, potassium, sodium, iron, manganese, and zinc in chaparral. These tables can be used by the land manager to give a percentile rank to any values for vegetation analyses or to assess probable values to expect for fertility storage in the soil or vegetation of chaparral stands.
