Strategically managing livestock grazing in arid regions optimizes land
use and curtails the damage caused by overcultivation. Controlled
grazing preserves soil quality and fosters sustainability despite
resource limitations. Uneven resource distribution can lead to diverse
grazing patterns and land degradation, particularly in undulating
terrains. In this study of a complex desert landscape encompassing dunes
and interdunes, we developed a herbivore foraging algorithm based on a
Resource Selection Function model. Our findings reveal that cattle
prefer areas with abundant vegetation and proximity to water sources
while avoiding higher elevations. However, abundant resource
availability mitigated these impacts and enhanced the role of water
points, particularly during late grazing periods. In summary,
resource-driven decisions influence livestock grazing patterns,
indicating that effective management should prioritize resource-based
strategies such as enhancing food resources near water points as
vegetation declines. Further, thoughtful water source placement and the
subdivision of pastures into areas with varied terrain are crucial
considerations.
