Description

The dataset contains records of otter (Lutra lutra, Mammalia) collected in plots along lower river Tua sub-basin and included in theEcological monitoring Program of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected in November 2010 and March 2011, during field visits to 12 sampling plots with favourable habitats for otter located in the lower river Tua and some tributaries. The occurrence of the target taxa was documented through 22 observations of scats identified as belonging to the target species.

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 river Tua sub-basin in the municipalities of Carrazeda de Ansiães, Alijó, Murça and Mirandela.

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. Twelve sampling plots were setup in this area. In each sampling point, a 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. Each plot was visited once in November 2010 and once in March 2011, in dry or light rain periods, to minimize the chance of lexiviation of the feacal material. The scats were identified "in loco" by expert researchers. Only presence/absence information was retained.

Quality Control

All identifications were performed by qualified technicians
