Lobo Rio Tambopata – Wildlife Amazon

Lobo Rio Tambopata – Wildlife Amazon: Pteronura brasiliensis is one of the largest carnivores of South America and is located at the top of the food chain with other predators such as the jaguar and alligator. His body reaches up to 2 meters in length and weigh 32 kilograms (Davis, 1978; Duplaix, 1980; Staib & Schenck, 1994).

Wolf River your hair color is dark brown, except in the limbs and chest, which has a color ranging from very pale hue to a yellow-orange (Gmelin, 1788, in Duplaix 1980). Their skin is thick and waterproof, with two different types of hair: the longer create a layer of insulating air that does not let the water into the dermis (Foster-Turley et al, 1990; Schenck & Staib., 1994). His body is elongated and fusiform, with long, flexible neck, highly adapted to aquatic locomotion. The mouth is surrounded by touch hairs, called vibrissae, that indicate the current and pressure changes (Duplaix, 1980; Schenck & Staib, 1994). The toes are webbed together by black and the tail is flattened dorsoventral, hence its name, since Pteronura is a Greek word meaning “tail-shaped sword” (Schweizer, 1992).

Pteronura brasiliensis is monogamous, reaches sexual maturity at two years and it is estrus every 21 days, for five of which the female is receptive (poliestrous) (Laidler, 1983). The gestation period lasts between 65 and 70 days and the litters are one to four young. (Trebau, 1978; Wunnemann, 1991, 1992 cited by Schenck, 1999), The pups spend the first month of life most of the time in burrows; then they open eyes and prepare to swim (Autuori & Deutsch, 1977 cited by Schenck, 1999).

Wolves river from 2 months receive solid foods and continue the group. Older siblings help the parental care of the young, bringing them food, playing with them, teaching them important survival behaviors and loading them into their parents (Staib, 1995). The cubs remain a time of 2 years with their parents, regardless of other pups born (Laidler, 1984).

The otter, also known as Giant Otter is a very friendly and sociable species that lives in the tropical forests of South America, mainly in rivers, lakes, lakes, streams and wetlands, where is the food needed for sustenance.

The fish with the otter feeds are hunted quite easily thanks to their whiskers which serve to detect prey, the interdactilares membranes that provide quick swim and aerodynamic shape of its long and flattened body, and his tail that serves as rowing and steering.

The otter has a brown fur with white spots on the neck, weighs between 25 and 32 kilos and measures 1.5 to 2 meters long, including thick tail measuring about 55 cm, and its round head, big eyes, small ears and a nose similar to ours.

It is a diurnal species that prefer to rest overnight, along with the rest of the group, in burrows usually built on lakes, under the branches and trunks of fallen trees. The young accompany the group until they reach sexual maturity at 2 or 3 years old then, both males and females, they go in search of space and individuals of the opposite sex.

Once a couple and after more than two months of gestation, the female WOLF RIVER usually have between 1 and 4 pups, only once a year, usually in the dry season. After 2 months of age children can accompany the new group to fish, however continue breastfeeding until the fifth month.

It should be noted that for several decades the giant otter populations were decimated by the desire to get their thin skin. Today is also threatened by habitat destruction, overfishing, pollution of waters and local tourism.

Following an investigation conducted between 1991 and 1995 in the Manu Biosphere Reserve, it confirmed the existence of only 60-65 otters, although that area is one of the most biodiverse country. Today, the state protects this species in different conservation units like Manu, Bahuaja Sonene, Yanachaga Chemillén, Pacaya Samiria and Tambopata.


The otter is included in Appendix 1 of the CITES agreement, which prohibits trade in protected species. In Peru, it is considered an endangered species, according to DS No. 013-99-AG of May 13, 1999.

The evaluation of otter (Pteronura brasiliensis) is part of a job monitoring the species in the long term by the Frankfurt Zoological Society has shown a gradual but steady increase in population, methodology raised during these twenty years Work has answered several questions about the ecology, behavior, distribution of the species and it has generated other questions about their conservation needs over time, especially in the protected areas Peruvian state.

Natural Protected Areas and the Tambopata National Reserve, Manu National Park and Bahuaja Sonene National Park, home to the largest population of giant otter. But the restricted distribution of the otter, south east of the country, makes the development of global strategies for the conservation of the giant otter in and out of the current state conservation areas indispensable, it is necessary to develop new mechanisms, methodologies and generate better and more working groups to benefit the conservation of the species and its habitat.

The Tambopata National Reserve is home to a sizeable population of giant otter, the lakes present along the Tambopata River are an important habitat for the giant otter in our country (Hajek and Groenendjink, 2006, Schenck and Staib, 2001). The hierarchy of protection that has protected area and presenting large bodies of lentic waters of this area, which encourages groups of Rio Lobo stably use it as the Sandoval family, which can develop and reproduce successfully, these meta-populations allow the survival of the species in this area (Schenck, 1999).

The Bahuaja Sonene National Park is an important area for the otter, the main lodge family groups, the river Heath acts the same as the natural border between Peru and Bolivia, however residents of the lakes groups of Heath, easily cross these limits, since they know no borders. Evaluation and monitoring 2010 achievement recorded in the Tambopata National Reserve, a total of 50 individuals (38 adults and 12 pups), sightings were recorded in three rivers (Azul, La Torre and Patuyaco) in Jack Creek and 5 You lakes. In the Bahuaja Sonene National Park totaling 10 individuals in the lakes of Peruvian territory, and a total of 30 individuals in 15 lakes of which the species was sighted in 07 lakes registering. While nearly all the lakes is any indication of their presence was recorded.

The restricted distribution Wolf River, south east of our country and the fact that none of the ANP of Mother of God protect a genetically viable population, makes the development of global strategies for the conservation of the giant otter in essential and outside current state conservation areas, it is necessary to develop new mechanisms, methodologies and generate better and more working groups to benefit the conservation of the species and its habitat.

The evaluation and monitoring of wolf work in coordination with the head of the Tambopata National Reserve (RNTAMB), head of the Bahuaja Sonene National Park (PNBS) Partial Agreement and Operations Management Components Biological Monitoring and Research in the National Reserve Tambopata and in the field of Bahuaja Sonene National Park in the department of Madre de Dios (AIDER), obtaining the support and collaboration of both institutions.


lobo rio amazonThe Rio Lobo (Pteronura brasiliensis), also known as giant otter, is one of the largest and sociable of the 13 otter species in the world, is uniquely adapted to life in rivers, lakes and swamps of the tropical plains. He is currently listed by the Specialist Group Otters IUCN as a particularly endangered species, according to the International Agreement on Trade in Endangered Species (CITES), the otter is located in Appendix 1 in the category of more stringent protection and Peru is classified as “Endangered” by Supreme Decree No. 034-2004-AG, as in the past this species was very persecuted for their fur, which would have caused a significant decline in their populations.

In the decade of 1940 and 1970 the population of otters was drastically reduced by hunting for skins, so that according to official figures from Peru about 24,000 skins were exported, (Brack-Egg 1978), which probably represent a fraction of the real number. Currently, the main threat to the survival of the species is habitat destruction (Chehebar 1990, Bisbal 1993), primarily through population growth and disorderly in the basins of the Amazon, Orinoco and La Plata rivers economic activities, including logging, mining, fossil fuels, hydropower construction, (Carter, 1997), and more recently irresponsible practices of nature tourism. (Calvimontes, 2006). Even the state of Rio Lobo is uncertain, considering that for subsistence species require large territories, having being pro the lakes of the Amazon, rare habitat and frequently used by humans.

The Frankfurt Zoological Society began studying Wolf River over 20 years. Working in studies of ecology, population dynamics and conservation programs by cochas use planning and environmental education. Thus the program cochas use planning has been particularly successful facilitating the recovery of wolf populations in the lakes and increasing the attractiveness and success of wolf sightings by tourists in them.

The otters, are animals that live in social groups, conduct all activities together, are very charismatic and easy to see what makes him this kind in a special attraction. (Staib, 2005. Ferreyra, 2004. Schenck, 1999). RN in Tambopata and its buffer zone can be found lakes with tourism. Including the importance of Lake Sandoval, Cocococha within the territory of the reserve, and the oxbow oxbow within its buffer zone states, together representing a vital population of the species of Tambopata core.

Similarly the lakes of the watershed of the river Heath of Bahuaja Sonene, are areas with relatively high potential to host large groups of giant otters. The activities developed by the Wolf River Project and presented SZF results in 2010. Results obtained Annual population monitoring of otters in the Tambopata National Reserve and Bahuaja Sonene National Park.

Research area of ​​Rio Lobo:

The evaluation and monitoring of Rio Lobo focused on two ANP:

  • Tambopata National Reserve
  • Bahuaja Sonene National Park


The Tambopata National Reserve is located south of the Rio Madre de Dios, in the districts of Inambari and Tambopata Tambopata province, over an area of ​​278,288 Ha (Master Plan 2003).

The policy location:

  • Madre de Dios – Tambopata – Tambopata
  • Madre de Dios – Tambopata – Inambari

The Bahuaja Sonene National Park, is located between the departments of Madre de Dios and Puno, its buffer zone covers the area of ​​Colorado in Puno province of Sandia to the native community of Kotsimba in Madre de Dios and has an area of 262,941 ha. The area occupied by the park and its buffer zone is 70% in the region of Puno and 30% in the region of Madre de Dios. (PNBS Master Plan).

The policy location:

  • Madre de Dios – Tambopata – Tambopata
  • Madre de Dios – Tambopata – Inambari
  • Puno – Sandia – San Juan del Oro
  • Puno – Sandia – Limbani
  • Puno – Carabaya – Coasa

Using otter habitat:

The habitat, considered the conglomerate abiotic and biotic factors that together characterize the type of place where an animal (Partridge in 1981 Krebs and Davies quoted in Schenck, 1999) lives. It is important to know the lakes (otter habitat) to understand the relationship between population densities, distribution of food and places of residence, place of rest or other resource, achieving determined by analyzing habitat understanding of the relationship system between species and their environment. Signs of the presence of the otters are taken into account in determining habitat use for which it must take into consideration the following:

  • Campgrounds: They are irregular areas of land, several square meters, generally located on the banks of a body of water, above the water level, which have been cleared of vegetation by wolves and the group uses them to defecate, mark your territory, drying, resting and preening. All camps have one or more areas or group dial is classic latrines and find hard parts as fish bones and scales that have been excreted.
  • Burrows: Located on high banks of the water body, consisting of one or more tunnels which are directed towards one or more oval chambers have been excavated on the bank of a body of water, the entrance to the burrows are usually free vegetation and wet with visible scratches left by the wolves in and out of it. They are used for sleeping and care of offspring. There are usually nearby camps. These areas are more sensitive to human presence.
  • Footprints: The most important features of the footprints of the otters are its size and the length of their fingers, like the marks left by the tips of human fingers. Only they recorded when they are not associated with any of the above evidence.

The camps and lodges, were recorded as recently used (UR) and not recently (NUR) used in accordance with the methodologies, defining as “recently” about two weeks since the last time they were used by a family of wolves. (Groenendjink, et al, 2005).
