Conservation Status of Telmatobius intermedius and Other Amphibians in the Pampa Galeras National Reserve – Barbara D’Achille, Ayacucho, Peru


The species of the family Telmatobiidae are endemic from South American Andes, they are distributed from central Chile to northern Ecuador, through Bolivia and Peru, above 2600 m.a.s.l. these frogs inhabit wetlands ecosystem of páramos and Andean subparamos and also dry and wet puna. 61 species are recognized In South America and 25 of these are distributed in Peru.

The species Telmatobius intermedius (Figure 1) is a semi-aquatic frog, it’s found under stones, in streams, and puquiales, in the pools formed in these environments. It was described by Dr. J. Vellard in 1951, since that date there is no trace about the species. The only known record is from the type locality in Allipaca town at 3300 m.a.s.l., near to Puquio, in the department of Ayacucho, in the Andes of southern Peru (Vellard 1951),.

In December 2014, researchers from “Asociación Pro Fauna Silvestre” visited the town of Puquio and found individuals of Telmatobius sold in the local market for human consumption as “frog extract” (Figure 2). With an examination of their morphological characteristics we deduce that it was Telmatobius intermedius. After consulting the source of these frogs, we decided to go to this town to look for more individuals of these frogs and confirm the species identity. In an evaluation of a transect of 100 meter installed in a creek near to Puquio we found a small population of Telmatobius and counted three adult frogs, including two mal, one female and many tadpoles in different stages of development. This creek is severely contaminated and presents a very low flow; nevertheless, this frog can survive in this dirty environment polluted by plastic and grazing livestock excrements (Figure 3).

Currently, T. intermedius is considered like a Data Deficient species (DD) by Peruvian legislation (Supreme Decree Nº 004-2014-MINAGRI) and also by the IUCN. The knowledge of their real distribution, status of their populations and information about their ecology is uncertain. T. intermedius is endemic to the Andes of Peru; one of the greatest threats that could suffer the species is the presence of chytrid fungus. However, it is not known if the fungus could affect them.

Puquio is located at 28 km NE from the National Reserve of Pampa Galeras – Barbara D’Achille, this protected area was created on May 18, 1967 and safeguards an area of 6500.00 hectares, with prevailing high Andean grasslands ecosystems that home a population of T.intermedius and other species of amphibians Telmatobius jelskii (NT), Gastrotheca marsupiata (LC), Pleurodema marmoratum (LC) and Rhinella spinulosa (LC)

The aim of this study is to evaluate the current condition of Telmatobius intermedius and other amphibians in Pampa Galeras National Reserve; and also in the type locality Allipaca – Ayacucho, where we want to assess the population status, identify the main threats to the species and determine the prevalence and intensity of the fungus Batrachochytrium dendrobatidis.
