Fauna

The Meullín-Puye Nature Sanctuary is home to 40% of the total numbers of individual species found in the Aysén Region: 11 species of amphibians, 77 birds, and 21 mammals.

Some of the most representative species in the area are the Magellanic woodpecker (Campephilus magellanicus), South American snipe (Gallinago paraguaiae magellanica), peregrine falcon (Falco peregrinus), pudú (Pudu puda), southern river otter (Lontra provocax), puye gigante (Galaxias platei), and Darwin’s frog (Rhinoderma darwinii).

There are 28 species of birds and mammals classified in some conservation category.

It should be noted that this area is characterized by being highly isolated due to low levels of anthropic intervention, especially in the basin of the Yulton and Meullín lakes. These conditions have made it possible to observe structures and processes in their natural states. In this respect, there are no traces of domestic animals in the Cuervo and Marta river basins, or introduced wild species, with the exception of mink.

Amphibians

Eleven species of amphibians have been found in the area. These include the Patagonian toad (Bufo variegatus), which belongs to the Bufonidae family; nine species of amphibians from the Leptodactilydae family; and the endangered Darwin’s frog (Rhinoderma darwini), which is a member of the Rhinodermatidae family.

Birds

A total of 77 bird species have been seen in the area, accounting for 41% of the avian diversity in the region. The Passeriformes order is represented by 28 species, where the Tyrannidae and Furnariidae families account for the largest diversity of species, with seven of each. Other important orders include Falconiformes, Anseriformes, and Ciconiformes, with 11, seven, and five species, respectively. Eight of the species recorded fall into a conservation category.

Vulnerable species include the Magellanic woodpecker (Campephilus magellanicus), the South American snipe (Gallinago paraguaiae magellanica), and the peregrine falcon (Falco peregrinus).

The various bird species can be grouped into two environments: one of high-altitude grasslands and all the different types of wetlands, and the other, formed by low- and high-altitude forests and heathlands, as well as low-altitude grasslands.

Mammals

A total of 21 mammal species have been recorded in the area, seven of which are carnivores, along with three herbivorous even-toed ungulates, one herbivorous odd-toed ungulate, nine species of rodents, and one lagomorph.

These species represent 12% of the mammalian diversity in the country and 42% of the mammals that live in the Aysén Region. The most diverse family is the Cricetidae, which are small rodents. Seven of the species found are classified in some category of conservation.

Endangered species include the pudú (Pudu pudu) and the southern river otter (Lontra provocax). The latter can be found around the Meullín and Yulton lakes. All of the riverbanks where traces of the southern river otter have been found are characterized by developed forest extending to the edge of the river and the presence of abundant vegetation, trunks, and shelters.

The most abundant species of micromammals include the olive grass mouse (Arbothrix olivaceus) and the long-haired akodont (Abrothrix longipilis). There are also recorded sightings of the Chilean climbing mouse (Irenomys tarsalis).
