The Vicuña

A wild ancestor to llamas and alpacas, the vicuña (Vicugna vicugna) is one of two South American camelids that has never been widely domesticated, with the other being the guanaco. Vicuñas are native to the central Andes of Peru, Bolivia, northern Chile, and northwestern Argentina.

Vicuñas are considerably smaller than most camelids. On average they stand about three feet high at the shoulders and weigh 100-150lbs. Unlike alpacas, vicuñas do not vary much in coat color, and are usually light brown on their backs with longer white fur covering their necks and undersides.

Vicuñas typically live in family groups consisting of 5-20 animals. This includes a single adult male, several adult females and their young. Most family groups live in two territories, a daytime grazing area, usually in lowlands with nutrient-rich grasses, and a nighttime sleeping area higher up in the mountains. The dominant male in these groups never allows family members to venture farther than 200 feet from one another at any time.

Though vicuñas do face natural threats from pumas and foxes, their largest threat comes from humans. Unrestricted hunting from the time of the Spanish conquests through the 1960’s had reduced the vicuña population to only about 6,000 individuals. They were declared endangered in 1974; since then, conservation efforts have allowed the vicuña population to soar to a current level of 350,000.

The Columbian Exchange

Christopher Columbus first arrived in the Americas on October 12th, 1492. Columbus Day is celebrated in the United States today in memory of that event and how it undoubtedly changed the world forever. One of the biggest impacts his arrival had was due to the number of animals and crops introduced to the New World; this is known as the Columbian Exchange.

From a biological perspective, both North and South America were very different places before European settlers arrived. With the exception of alpacas and llamas there were virtually no large animals in the Americas suitable for domestication. The Europeans introduced cattle, sheep, goats and of course, horses; all animals considered vital to both the history and modern economies of the Americas.

The new presence of these animals, all either nonnative or extinct in the Americas for thousands of years, changed life for native peoples significantly; large livestock animals allowed farming cultures to become ranching cultures, and the horse allowed native tribes the nomadic freedom to hunt large animals such as bison.

With trade between Europe and the Americas open for the first time, some New World animals were introduced to Europe as well. Turkeys, llamas, alpacas and guinea pigs were all introduced to Europe and Asia, where they are now common.

Though there is some debate over who actually “discovered” the New World, there is little doubt that the animals introduced during the Columbian Exchange affected it in a very profound way.
