Data file of main results examined in "Accelerated vegetation succession but no hydrological change in a boreal fen during 20 years of recent climate change"

This is the data file of main results examined in our paper "Accelerated vegetation succession but no hydrological change in a boreal fen during 20 years of recent climate change" (Ecology and Evolution, doi.org/10.1002/ece3.7592). The data file consist of the cover of bryophyte groups, plot designations to EUNIS habitat types, and water chemistry (pH and base cations) and water-table depth for each sampling point in 1998-1999 and in 2018.
