Conservation Status

[NE] [VU D2:3.1:2011]

Trichomycterus dali is endemic to Brazil, and is distributed in the Serra da Bodoquena, municipality of Bonito, MS. The extent of occurrence is estimated at 600km2. It is not located in a protected area, and the whole area is located around the Parna da Serra da Bodoquena. Two major threats affect the species: the expansion of the limestone mining activity in the southern portion and the expansion of livestock in the northern portion of the species distribution. These regions represent two locations. These activities are causing pollution and lowering of the water table, in addition to the complete destruction of cave systems around the Park. For this reason, the species is classified as Vulnerable (VU) under criterion D2. It is essential to establish protective measures of the karst systems of the Serra da Bodoquena. Studies that elucidate possible differences between northern and southern populations are also needed, such as phylogenetic and molecular biology studies." [Google Translate]
