Herpetofauna Monitoring Biodiversity Surveys in Aguada Pichana Este, Añelo, Neuquén, Argentina – 2022/2023/2024 – TotalEnergies E&P Austral B.V.

Study Extent

The survey was developed in 4 environmental units already detailed in the geographic coverage section.

Sampling

In the four environmental units described, 22 transects were determined, 8 in the BA area, 6 in the PA area, 4 in the QYC and 4 in the AT area. Each transect has a 500 m length and a 50 m width. There were also added to the survey 6 observation points that can complement the information collected with the observation in the transects. These information is summarised for every sampling event in the column Location ID, e.g: APE-PA-13, where APE is the abbreviation for the site, PA is the abbreviation of the environmental unit and then there is the number of the transect.

Method steps

1. The proposed transects were traversed on foot by two observers, georeferencing the findings and specifying, as far as possible, the life stage of the individuals (juveniles, adults, and sex).
