A 16S rRNA dataset of Las Tablas de Daimiel National Park

Wetlands are ecosystems of environmental importance due to their role as biodiversity shelters. However, the intense anthropization of the landscape have propelled a decline in water quality and quantity across global wetlands during the last decades. Under this context, microbial communities offer an accurate approach to better understand the conservation state of these freshwater bodies. With the goal of contributing to environmental monitoring of wetlands of global significance, we here present a newly-generated 16S rRNA dataset derived from ‘Las Tablas de Daimiel National Park’, a wetland system in Spain designated as a Biosphere Reserve by the UNESCO and a Ramsar site of international importance. Samples were collected across four different stations in the region, covering both the water column and the sediments, and environmental metadata was measured. In total, our dataset compiles 1,766 archaeal ASVs and 19,855 bacterial ASVs covering 11 and 64 phylum-level groups, respectively. This dataset offers a valuable resource for future monitoring work at the ‘Las Tablas de Daimiel’ National Park to improve its health and conservation.
