The lack of statistically significant differences in leaf carbon isotope ratios, average leaf mass per leaf area, flower counts per unit of canopy volume, mature seed counts, and tree population densities could be interpreted in two ways: either this desert phreatophyte is consistently able to obtain sufficient water from deep below the soil surface; or water availability might be temporarily similar upstream and downstream from berms during periods when most photosynthesis, leaf, and flower production occurs.
