While not considered an endangered specie in Southern Argentina and Chile dead Guanacos are a common site throughout this region where they are entangled on fences. Studies have found that annual yearling mortality on fences (5.53%) was higher than adult mortality (0.84%) and was more frequent in ovine (93 cm high) than bovine (113 cm) fences.
Although the guanaco is listed as a species of least concern by the International Union for Conservation of Nature and Natural Resources, populations in the northern part of the animal’s range have declined substantially as a result of habitat loss and competition with other grazing animals, and the governments of Peru, Paraguay, and Bolivia ...

Feb 26, 2020 · Guanacos (Lama guanicoe) are considered critically endangered in Bolivia and Paraguay. Fewer than 200 exist in Bolivia and as few as 20 in Paraguay. Guanacos in Bolivia and Paraguay are threatened by habitat loss and poaching. They live in the Chaco, a dry-forest ecoregion that’s one of the most heavily deforested areas on the planet.
Although they seem delicate, guanacos can weigh up to 265 pounds (120 kilograms). Male guanacos are larger than the females. All guanacos have a thick, wooly coat that can be light brown, brownish yellow, or a rusty red. Their belly, rump, and the backs of the legs are usually white; the head, ears, and nape of the neck are gray.
In general, guanaco habitats are characterized by high winds, low precipitation, and low primary productivity (de Lamo et al., 1998; González et al., 2006). Guanacos are distributed over an elevation range from sea level to 4,500 m (Franklin, 2011).
Aug 22, 2019 · Guanaco and chulengo. Mint Images/ Art Wolfe / Getty Images Conservation Status . The IUCN classifies the guanaco conservation status as "least concern." The population is estimated to range between 1.5 to 2.2 million animals and is increasing. However, this is still only 3-7% of the guanaco population before Europeans arrived in South America.
In the northern part of the Guanaco’s range, numbers have fallen dangerously low. However, although many populations have been reduced drastically or isolated by habitat loss and fencing, total numbers are still estimated as high as two million, and the species is listed as Least Concern by IUCN.
