EDP Baixo Sabor: Construction Phase – Invasive Species (work fronts) [2010-2014]

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 2,221 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.

Geographic Coverage

The data were collected in a variable number of transects in the work fronts on the lower Sabor river valley, from the Feiticeiro Dam (downstrem the main work) and Vilariça stream to 42 km upstream, in the municipalities of Torre de Moncorvo, Alfândega da Fé, Mogadouro and Macedo de Cavaleiros.

Taxonomic Coverage

The taxonomic coverage of this dataset spans 1 phylum, 2 classes, 9 orders, 12 families, 18 genera and 21 species.

Temporal Coverage

Project Data

The dataset contains records of vascular plants collected in the lower valley of River Sabor (NE Portugal) in the scope of the long-term Ecological Monitoring Program (PME) of the Baixo Sabor Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A, to assess the spreading capacity of exotic invasive species in the work front (dam structures and complementary works – dam yards, quarries, heaps, work front and road accesses) during the dams construction period (2010-14). Plant inventories were taken in line transects performed on foot, in all work front sites along 42 km upstream, in the Sabor valley, and in the Vilariça stream. The occurrence of the target species was documented through 2152 observations of occurrence of 21 species. The most common species were Phytolacca americana (1006 records), Datura stramonium (348) and Ailanthus altissima (308).

Sampling Methods

The methodology used in the work fronts consisted of line transects, generally carried out on foot, to detect invasive exotic species. The area surveyed was 30 m to each side of the transect axis. Each individual species (or habitat) of interest was mapped with a Garmim Colorado 300 GPS. In each patch of invasive species detected, the number of individuals (or the area occupied by) the relevant species was counted (or estimated). In the case of construction works such as yards, heaps and quarry, among others, an S-shaped path was performed, trying to cover as much area as possible. A record was also kept on the level of damage caused to the patch by the work (“TD” = totally destroyed; “PD” = partially damaged, or “ND” = not damaged). The partially damaged (PD) category ​​means that part of the patch had been deforested or buried, eliminating part of the individuals or affecting part of the nucleus area. In general, each patch was visited once per season and year. However, terrain and logistical difficulties dictated that, sometimes, more than one trip per patch was necessary. Most species were identified “in loco” although, in some cases, samples were collected to further identification in the laboratory. The nomenclature is mostly in accordance with Flora Ibérica (Castroviejo et al., 1986-2009) for the volumes already published and for Nova Flora de Portugal (Franco, 1971, 1984; Franco & Rocha Afonso, 1994, 1998 and 2003) for the remaining groups.
