Since 1972, twelve scientists representing several research disciplines have collaborated in integrated studies to determine the chronic effects of photochemical oxidant air pollutants on a western mixed conifer forest ecosystem. An enormous amount of data has been collected, describing present and past natural conditions of twelve subsystems comprising the conifer forest ecosystems of the San Bernardino Mountains of Southern California. A computer data bank is being developed to allow efficient storage and retrieval of these numerous data sets. The systems simulation modeling process has begun early in 1975. The basic unit for modeling purposes was defined as the forest stand, which may be comprised of from 10 to 200 trees with equivalent land areas of from 100 to 25,000 sq m. Time resolution varies according to the subsystem in question and may be hourly, daily, biweekly, monthly, seasonal, annual, or multi-annual. The subsystems receiving attention at the stand level are defined as: tree population dynamics, oxidant flux canopy response, stand-tree growth, stand moisture dynamics and microclimate, stand mortality responses related to bark beetles and root disease, tree seedling establishment, cone and seed production, litter production, litter decomposition, and small mammal population dynamics.
