Summary

This study demonstrates that grazing livestock follow Lévy walk movement patterns that can be modelled and used to predict soil structural changes. The authors developed the 'Moovement model' integrating GPS-derived movement data with soil dynamics simulations, finding that rotational grazing produces comparable soil disturbance to conventional grazing despite supporting higher stock densities. The work suggests that spatially-explicit modelling of livestock movement offers a quantitative framework for optimising grazing strategies to minimise adverse soil health impacts.

UK applicability

The findings are directly applicable to UK grassland management, where both conventional and rotational grazing systems are widely practised. The model could support UK farmers and advisers in evaluating grazing strategy trade-offs between productivity, stocking density and soil structure preservation.

Key measures

Livestock movement patterns (GPS-tracked), soil bulk density, grazing intensity and spatial distribution under conventional versus rotational grazing systems

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 soil properties using a newly developed 'Moovement model' that couples animal movement with soil structure dynamics.
