Abstract: This research will examine the carbon dynamics associated with major natural and anthropogenic disturbances. Carbon flux measurements and carbon dioxide concentrations were taken along an urban to rural gradient from Baltimore, MD, to the NJ Pine Barrens. The gradient incorporates the effects of land use, natural disturbances, and forest management in forested lands and heavily vegetated non-forest lands. The Cubhill tower in Baltimore, MD, is in a mixed deciduous forest, and monitors carbon dioxide concentrations and carbon flux in the urban/suburban environment. The three towers in the Pine Barrens of NJ, monitors carbon flux under fire management and disturbance, going from a mixed overstory oak forest in the west, to a mature oak and pitch pine association, and reaches a mature pitch pine –scrub oak vegetation in the east. Results are presented showing the effects of anthropogenic cycles associated with the work week, land use change, prescribed burning, gypsy moth outbreak, and climate variability.
