Living Fences in Costa Rica a Growing Idea
Farmers across Central America plant living fences because these
green barriers are a more economically feasible and readily accessible
method for containing livestock and protecting crops.
....
By providing some shade and serving as windbreaks,
living fences can significantly decrease the amount of energy farm
animals need to regulate their body temperatures. As livestock allot
this extra energy to growth and, in dairy cows, producing milk, farmers
experience higher yields, whether in meat or milk, for planting living
fences.
This is simply cool. (Ha! Literally, too!)
