Effects of grazing intensity on plant richness and diversity: a meta‐analysis

open access: yes, 2018
Most of our knowledge of the effect of grazing on grassland structure is based on grazed–ungrazed contrasts. The effects of grazing in the most common scenario, where grazing intensity varies from low to high grazing intensity, are less known.

COMPARISONS OF CATTLE GRAZING AND SHEEP GRAZING

open access: yesProceedings of the New Zealand Grassland Association, 1976
Controversy has surrounded the possible differences in pasture production which result from grazing by cattle or sheep. Experiments conducted over the 1972-76 period show that pasture production under grazing by sheep is greater than under grazing by cattle under similar intensive managements.
