Optimizing grazing intensity boosts desert grassland biodiversity and biomass.
A study looked at how different levels of grazing affect plant communities in a desert grassland. They found that when there was no grazing in spring, light grazing in summer, and moderate grazing in autumn, the plants had more biomass and diversity. Perennial grasses did better in these conditions compared to other grazing levels. Shrubs and semi-shrubs were more important in areas with severe grazing in spring, severe grazing in summer, and light grazing in autumn. The variation in plant biomass was lowest when grazing was managed in this way. Overall, it was suggested that this grazing pattern is the best for maintaining a healthy plant community in the desert grassland.
