EDP Foz Tua Otter (Lutra lutra) [transects] - Ecological Monitoring Program (2011-17). Version 1.1. EDP - Energias de Portugal. Sampling event dataset https://doi.org/10.15468/fffnhb accessed via GBIF.org on 2022-07-03.

Description

The dataset contains records of otter (Lutra lutra, Mammalia) collected in the Rivers Tua and Douro sub-basins and included in the Ecological Monitoring Program (2011-17) of the Environmental Impact Assessment of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected between June 2011 and July 2017 during field visits to 12 sampling transects in the riverbeds of the selected water lines with favorable habitats in the river Tua sub-basin. The presence of individuals was recorded by direct observation of signs (scats and/or footprints).

Purpose

This dataset is part of a broader initiative whereby the company EDP - Energias de Portugal S.A. will made available biodiversity data collected during impact assessment and biological monitoring studies.

Sampling Description

Study Extent

The data were collected in the rivers Douro and Tua sub-basins, in the municipalities of Carrazeda de Ansiães, Vila Flor, Alijó, Murça and Mirandela, S. João da Pesqueira and Tabuaço.

Sampling

Sampling was designed to cover the course of the lower river Tua and its main tributaries from the mouth up to the northern limit of the Foz-Tua dam, and the downstream part of the three Douro tributaries, up to 5 km. Up to 24 sampling transects were setup in the Tua sub-basin and one more was located in each of the four Douro tributaries (systematically recorded only for 2011). Each transect up to 600 m was performed along the margins, looking for signs of presence (mostly scats) in suitable places (prominent stones and vegetation in the margins of the water line). The transect was interrupted when the presence of the otter was detected, but never before 200 m had been prospected. Each plot was visited once in dry or light rain periods (June-July), to minimize the chance of leaching of the fecal material. The scats potentially attributed to the species were stored and taken to the laboratory to molecular identification. Only presence/absence information was retained.

Quality Control

All identifications were performed by qualified technicians
