Fens and bogs are valuable research environments for paleoecologists due to ancient fossils that have survived in the peatland for thousands of years. A recent study carried out by the paleoecologists of Tallinn University of Technology reveals that the rich biodiversity of spring fens is a result of their millennia-long stable environment. The continuously high local richness in spring fens is contrary to the general decrease in biodiversity around the world caused by increasingly intensive land use.
