Résumé:
The Caatinga Biome has historically been considered an area poor in fauna and flora diversity,
with few endemic species and, therefore, low priority for conservation. Due to this fact, the
Caatinga areas were neglected for decades, resulting in the unbridled use of its natural
resources, leading to a great loss of habitat, making the Caatinga a highly fragmented biome
with only 7.4% of its territory occurring in areas protected. The little understanding about this
Biome is the result of less effort compared to other Brazilian Biomes over many years, in the
production of lists and inventories of species. In view of this, the present work aimed to carry
out a survey of the herpetofauna of the Caatinga in the Ecological Reserve Olho D'água das
Onças, municipality of Picuí, state of Paraíba. The work was carried out by recording the local
herpetofauna for 3 days a month, with 3 daily departures, during the months of February to June
(2021). For the capture and observation of the animals, an interception and fall trap (Pitfall)
was used and through active search. The registered animals were classified according to their
conservation through the Red List of the International Union for the Conservation of Nature
and Natural Resources (IUCN) and through the Ministry of the Environment (MMA).
Parameters such as: dominance and diversity, frequency of occurrence, relative abundance and
sample richness were used in order to know the proportion of the studied community. We found
31 species, distributed in 2 orders and 17 families. According to the data obtained for diversity
richness, it was possible to conclude that the area's herpetofauna is quite diverse and all species
are in a status of Least Concern (LC) in relation to their conservation. Therefore, the ecological
reserve, when it becomes a natural heritage, will contribute to the protection and conservation
of local biodiversity, also contributing to the expansion of protected areas in the Caatinga
environments, guaranteeing the sustainable use of natural resources, contributing to the
preservation, safe handling fauna and flora of the region, in addition to being used as a center
for scientific studies.
