    Abstract

    Results led to the development of a conceptual model, which describes that the presence of deep larger diameter roots in shrub areas form large open channels at deeper soil depths, facilitating deep-water percolation, while presence of thin shallow roots in grass areas form small open channels at shallow depths, causing water to remain within shallow depths. Over time these roots systems will alter their environment and facilitate storage and uptake of water and nutrient availability. The difference in rooting depth will decrease the competition for water between the shrub areas and grass areas and cause differences in water distribution and availability.
