Biomass components of mesquite (Prosopis juliflora (Swartz) DC) and palo verde (Cercidium floridum (Benth)) soil-plant systems were collected during spring, winter, and fall for 3 years to study the temporal distribution of the mass of understory vegetation and litter and the dynamics of nitrogen and carbon in all biomass components. Mass of palo verde litter changed seasonally while that of mesquite did not change. With exception of mesquite litter, mass of understory vegetation and litter did not change annually for either shrub. Seasonal and annual changes were observed in both N and C of selected shrub, understory, and litter components, but these changes were more prevalent in mesquite than palo verde. Seasonal changes appeared primarily related to N and C demand in regions of rapid growth. Annual changes appear related to weather phenomena which regulate decomposition, uptake, and growth.
