Environmental DNA metabarcoding of fish and amphibian occurrence in created biodiversity wetlands in Uppland, Sweden

The conducted study was done to determine the fish and amphibian occurrence patterns in created wetlands for biodiversity. The geographical study units were individual wetlands in Uppland, Sweden. For each wetland, the data contains all environmental variables considered and estimated within the study: Landscape forest within 1 km buffer, Size, Water vegetation, Flooded area, Year of creation, Connectivity to other wetlands. The data of amphibians and fish were obtained using environmental DNA metabarcoding, where a number of sequences were obtained. We report only whether the species eDNA was detected in a wetland or not (1/0). Data: data contains fish and amphibian occurrence data in created wetlands in Uppland, Sweden. Data collection description: Fish and amphibian occurrence in 52 created biodiversity wetlands in Sweden determined by using environmental DNA metabarcoding from water samples. This took place during June and July year 2018. The variables are described in detail in the documentation file. A file with geographical coordinates for the wetlands can be found in the linked data repository, where Site_ID could be used as a common identifier. A raw data file including the number of DNA reads can be provided upon request.
