Global meta-analysis: Sparse tree cover increases grass biomass in dry pastures

Agricultural and ecological droughts, extreme heat aridity have high impacts on livestock pasture systems worldwide. Finding ways to adapt production increase biomass under these new conditions is urgently needed. The availability of tree shade in pastures could potentially ameliorate the warm weather. Yet, effects cover productivity rangelands are hotly debated. We performed a global meta-analysis evaluate grass during contrasting seasons within same system along environmental gradients tropical temperate productive systems. also assessed levels canopy density at which observable. observed that trees facilitate dry seasons, especially tropics regions. These positive more likely occur intermediate evapotranspiration irradiance. Our findings suggest integrating might resilience current drier warmer conditions.
