Trees can benefit fauna. The most common examples are silvopasture where cattle, goats, or sheep browse on grasses grown under trees. In hot climates, the animals are less stressed and put on weight faster when grazing in a cooler, shaded environment. The leaves of trees or shrubs can also serve as fodder.
Wyatt and Earl both own cattle ranches in Texas. Wyatt's ranch is open and sunny with very few trees for shade. Earl's ranch has a mix of open, sunny areas as well as areas with a lot of trees and shade.
Will the cattle on Wyatt's farm be more or less stressed than the cattle on Earl's farm?
