Highly anthropised ponds, generally with low naturalness. There is an abundance of invasive species such as Pinus radiata, Cortaderia selloana, Buddleja davidii, Robinia pseudoacacia, Conyza sumatrensis, Dittrichia viscosa, Cyperus eragrostis and Cotoneaster horizontalis.
The ponds are recently colonised, with an immature ecosystem still evolving due to anthropic pressure. The most natural ecosystems are made up of bulrushes of the three Typha species (T. angustifolia, T. latifolia and T. dominguensis) and Juncus spp. with a predominance of J. articulatum and J. effusus. With different accompanying species, depending on the degree of naturalness: Centranthus ruber (possibly allochthonous), Schoenoplectus lacustris, Lythrum salicaria, Carex spp (C. riparia, C. cuprina, C. elata), Lagurus ovatus, Hypericum perforatum, Mentha suaveolens, Equisetum spp, Rubus spp, Holcus lanatus, etc.
Cortaderia selloana deserves a special mention, as it is the most abundant plant in the quarry's wetlands. It is an invasive species from southern South America that lives in degraded ecosystems.
The forest edge is mainly made up of Pinus radiata, although there are natural species such as Quercus robur, Salix spp., Alnus glutinosa, Corylus avellana, Phillyrea latifolia and Fraxinus excelsior. The submerged vegetation consists of species of the genus Potamogeton.
We also found some specimens of the beautiful orchids Anacamptis pyramidalis (photo 1 & 2) and Ophrys apifera (photo 3).
