The productivity and stability of grazed grassland rely on dynamic interactions between the sward and the animal. Combes et al. record 3-D canopy structures of swards of white clover (Trifolium repens) using an electromagnetic digitizer and adapted software, and synthesize virtual canopies in order to calculate bite mass of grazing animals and to determine effects on light interception efficiency (LIE) of the remaining sward. They find that bite mass and LIE values after grazing are more strongly affected by the initial structure of the sward than by bite form and placement.
