Domain consistency

Evaluation method description: The data of this dataset do not aim to achieve compliance with INSPIRE regulations. For this reason, its conformity is not evaluated and it is declared not conformant compliant by default.

Evaluation method description: The compliance of the metadata is evaluated using the "INSPIRE Reference Validator" web tool. The metadata is considered correct when the only errors reported are related with the main language of the metadata file. These errors are due to the fact that Catalan is not included in the list of official languages of the European Union.

Statement: Assessment index of the current and potential role of bird communities in the maintenance of plant communities dispersed by birds. A total of 15 species behave as dispersers of fleshy fruit seeds during the fall and winter in the SITxell area. This list consists of thrushes, sylvids and corvids: gray, blackbird, common thrush, red-winged thrush, cerdana gray, cap warbler, black starling, magpie, robin, black-headed warbler, common starling, jay, gralla, long-tailed warbler and smoked car. From these species, a relative indicator of their dispersal potential has been obtained, taking into account the percentage of frugivory of the total diet, and their metabolic rate (calculated from the weight of each species). Finally, for the elaboration of the final index, the value of the dispersal potential of each species was multiplied by the density estimated for each species in each square UTM 1x1 km. Finally, the values ??obtained for all the species present in each of these squares were added.
