Summary

This study characterises how grazing livestock move according to Lévy walk patterns and develops a novel 'Moovement model' that links animal movement behaviour to soil structure dynamics. By coupling GPS data from two grazing strategies with soil property predictions, the authors demonstrate that rotational grazing produces similar soil disturbance to conventional grazing despite higher stocking densities. The modelling framework offers potential for testing and optimising grazing practices to improve soil health outcomes.

UK applicability

The findings are directly applicable to UK pasture management, where both conventional and rotational grazing are practised. The model could inform UK agricultural policy and farm management decisions regarding grazing intensity and soil health, particularly as evidence-based approaches to sustainable grassland management gain prominence.

Key measures

GPS-tracked livestock movement patterns; soil bulk density; soil structure dynamics; grazing strategy comparison (conventional vs. rotational)

Outcomes reported

The study characterised daily and seasonal grazing patterns using GPS data from conventionally- and rotationally-grazed pastures and predicted spatially-explicit changes in key soil properties using the newly developed 'Moovement model'. Post-grazing bulk densities predicted by the model were consistent with field measurements, demonstrating that rotational grazing produced similar soil disturbance as conventional grazing despite hosting higher stock densities.
