Movhera Baixo Sabor: Construction and Reservoir Filling Phases – Vascular Flora and Habitats: species from prioritary conservation habitats - [2021-2023]

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 500 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

Data were collected along the lower Sabor river valley and its main tributaries, in a variable number of sampling locations representative of the selected communities of conservation relevance, from the river mouth up 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, 4 classes, 42 orders, 97 families, 424 genus and 754 species or infra-specific categories.

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, subsequently (2021) transferred to Movhera Hidroelétricas do Norte, S.A., to assess the temporal dynamics of species of selected habitats/communities of conservation relevance, before and after the dams implantation. This dataset includes results of surveys made in and around the area affected by the dams, from April 2021 to June 2023. Plant inventories were made along the lower Sabor river valley and in some tributaries, from the river mouth up to 42 km upstream. The occurrence of the target species was documented through 28046 individual observations of 754 species or infra-specific taxa. The most abundant species (percent cover > 20 m2) were: Quercus rotundifolia (89.8 m2), Q. suber (76.8), Junyperus oxycedrus (43.7), Fraxinus angustifolia (39.2), Alnus glutinosa (29.8), Rubus ulmifolius (27.6), Buxux sempervirens (24.8) and Oenanthe crocata (20.6).

Sampling Methods

Sampling was designed to cover the whole valley of the lower Sabor river and some of its tributaries, according to the specific target (natural communities or areas of intervention). Plant inventories were performed at each site, once per season, depending on the respective flowering period, from April to June, encompassing beetween 14 and 20 work-days. They were carried out on samples of variable size, depending on its stratification (ie, the number of strata) and its linearity (riparian galleries are linear structures). In this way, samples from natural areas (holm-oak and cork-oak communities) and in disturbed/intervened areas (exotic-dominated communities, work fronts, landscape recovery areas and reservoir margins) were of 400 m2 (20x20 m), whereas those of boxwood (Buxus sempervirens) and riparian galeries, of 100 m2 (50x2m) irrespectively of the type of area. The entire floristic list was listed up to the taxonomic category of species or subspecies, and through visual estimates a degree of coverage was assigned to each cast member, in percentage. These data were used in the calculation of several structure and composition parameters (not recorded in this dataset, which deals only with the plant inventories. Coverage estimates are presented up to the minimum area equivalent to 1% (i.e. 4 m2 in plots of 20 m x 20 m and 1 m2 in those measuring 50 m x 2 m) and take a standard minimum value of 0.5% when the cover is less than 1%. Specimens of doubtful identification were collected and pressed between two sheets of paper for later identification and deposit in the Herbarium of Vila Real (HVR -according to Index Herbariorum codes -Thiers, 2010). A list was kept of all species RELAPE, as well as of invasive/infestant species in each inventory.
