Many semi-arid regions are composed of mosaics of woody vegetation patches and interpatch spaces. Source-sink relations occur between these two phases, enabling primary production. Recent studies from the rangelands of the semi-arid Negev in Israel reveal that bimodal distribution of stocking density creates an additional phase-livestock trampling routes. The objectives of this commentary were to highlight the impact of this modification on primary productivity, and to provide a new insight regarding the functioning of these rangelands.
