Action C.9

C.9. Improvement of the state of conservation of the higrophylous habitats on the Isle of San Roque (SCI Parga-Ladra-Támoga)

 The change of use, however, has favored evolution towards fields of crops that consist of species foreign to the damp area such as Lolium sp., Trifolium sp., Dactylis sp

With the aim of favoring the natural state of the hygrophilous areas, and to give greater heterogeneity to the old crop fields, this effort proposes to act within an area of 2.6 ha (property of the Lugo County Council) with the aim of adequately developing the following habitats:

  • (3110) oligotrophic waters with containing very few minerals of sandy plains
  • (91E0*) alluvial forests of Alnus glutinosai and Fraxinus excelsior within a matrix characterized by the presence of Molinia meadows on calcareous, peaty or clayey-silt-laden soils
  • (6430) megaphorbic hydrophilous on the fringes of the plain and of the mountain to alpine floors.

This action will also permit the growth of existing population of the Narcissus pseudonarcissus subsp. nobilis on the island of San Roque, whose presence, because of past anthropic influence, was reduced in the damp area.

For the improvement of the state of conservation the hygrophilous habitats of the Isle of San Roque, it will be necessary to make a topographic correction in the plot of land subject to action, which will permit the recuperation of preexisting hydrological systems before the implantation of crops that caused the transformation.   Small canals that were eliminated and land depressions will also be recovered.  Furthermore, riparian trees, principally Salix atrocinerea, will be planted.

Increasing occupancy area and improving of the state of the conservation of the hygrophilous areas, such the effected populations of Narcissus pseudonarcissus sbsp. nobilis, has great importance for assuring its long term upkeep. Because of the context of the current climate change, the water conduction in the areas are increasingly more irregular and favor an increased development of the invasive exotic species.
