AbstractThe density, mean plant height and mean plant width of the perennial shrubs in a desert arroyo were compared with the soil water potential gradient along the arroya during one growing season. The data indicated that the density of shrubs was negatively correlated with the soil water potential gradient and shrub mean size positively correlated with the gradient. The variation in the vegetation parameters could not be accounted for by the soil water potential gradient alone.
