EDP Foz-Tua: Dipper (Cinclus cinclus) (point counts) - Ecological Monitoring Program [2013-16]

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 49 records.

1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Project Data

The dataset contains records of the Dipper (Cinclus cinclus, Aves) and other riparian bird species collected in point countss along the Tinhela River valley and included in the Ecological Monitoring Program of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected between April 2013 and June 2016 during field visits to six sampling points with favourable habitats for the Dipper. These point counts aimed to replace the linear transects of the regular program for this species, whenever these could not be performed due to security or logistic reasons. Therefore, they were set in the initial point of the transect they replaced. The occurrence of the target and associated taxa (riparian birds) was documented through 40 observations of Cinclus cinclus (5), Motacilla cinerea (29), Motacilla alba (4), Cettia cetti (1) and Alcedo atthis (1).

Sampling Methods

Sampling was designed to cover the main habitats for the Dipper and other riparian birds along the Tinhela valley affected by the Foz-Tua dam (the mouth) and upstream. A total of six count points was established along the river Tinhela, in the starting point of a corresponding linear transect. All points were sampled once in winter and 1-2 times in the reproductive period (spring), in the early morning or late afternoon. Each sampling point was surveyed for 30 minutes. Species identification and assessment of age and sex (when possible) were made “in loco”, with the help of appropriate field guides.
