Live tree fences reduce the variability of soil CO2 emissions.

Tropical deforestation for grass plantations for livestock production is responsible for about 30% of CO₂ emissions. Life fencing, which is the use of trees for fences, may help to decrease and balance CO₂ emissions. Villanueva-López et al. studied the impact of live fences of Gliricidia Sepium trees in livestock systems on soil CO₂ emissions. They found that CO₂ emissions did not differ with or without tree fences, but they also evidenced that tree fences reduced the diurnal and seasonal variability of soil CO₂ emissions.
