Waterlogged sites

Hygrophilous sites of the 7140 Transition mires and 7150 Depressions on peat substrates of the Rhynchosporion.

True jewels of Izki

The hygrophile vegetation and flora of Izki is of extraordinary richness and variety. There are an elevated variety of environments of this type in Izki which share some of the characteristics of the different types of habitats according to the classification in Appendix I of the Habitats Directive, so that what is found is a true mosaic of habitats, which can involve certain difficulties when interpreting the limits of each. Such is the case with the "Los Rosales" site, to the south of Mount Kapildui where habitats 7140 and 7230 (alkaline fens) can be distinguished or the areas of "Galbaniturri" and “Cobata” where 7140 and 7150 can be distinguished.
These environments provide shelter to Izki’s more sensitive plant species, some of them collected in the Basque Catalogue of Threatened Species: Drosera intermedia, Drosera longifolia, Epipactis palustris, Potentilla fruticosa, Primula farinosa, Spiranthes aestivalis and Triglochin palustres. Among the bryophites, two marchantiophytas stand out, Kurzia pauciflora and Odontoschisma sphagni, both very limited in their ecological range, exclusive inhabitants of old and well conserved sphagnum peat. There are also non-catalogued plants but of great interest and rarity, like the Carex davalliana, Rhynchospora fusca and Rhynchospora alba, or the Cross-leaved heath (Erica tetralix) which form remnants of wet heath in some flooded areas (4020*). It stands out that the population of Rhynchospora fusca of the Galbaniturri wetland is the most numerous of the Iberian Peninsula.
The other hand, the presence of sphagnums in the sandy areas of Izki is a feature of notable singularity because they are the most southern sphagnals of the Basque Country.

Its threats

The waterlogged habitats occupy less than 1% of the total surface of the Izki SCI and present different states of conservation. Among the main threats are the ranching pressures in these environments, the role that the domestic herbivores play in its conservation are not clearly established. These habitats are made up of bodies of water which is why they are used intensely by cattle. Although the role that cattle play as a rejuvenating agent for these environments, there exists an elevated concern given that some of these populations of rarer species are so small that any sudden change could have vital consequences.
