Economic Importance for Humans: Positive
Llamas are domesticated animals, and so are inherently important to human economies. The thick, coarse wool of llamas is valuable. These animals are sheared every two years, yielding about 3 kg of fleece. Farmers have used L. glama to curb predation of sheep by canids. By incorporating a few llamas into their sheep or goat flocks, studies indicate that predation drops sharply. Llamas have also been used as golf caddies and as farmyard pets. Historically llamas were used to haul loads over the Andean mountains because of their ability to carry burdens in excess of 60 kg for up to 30 km per day.
