Jaak-Albert Metsoja with collegues published a paper about the effects of mowing on dry and moist floodplain meadows. They compared the vegetation of mown and unmown floodplain meadows of Alam-Pedja Nature Reserve. Data was sampled in 2000 and 2010 at Rivers Pedja and Põltsamaa. They found that mowing increased the species richness of relatively drier plant communities on one of the study sites and changed the species composition and decreased spatial turnover on all sites and plant communities. The changes in species composition were most pronounced on relatively drier and more elevated plant communities and most subtle in the talll sedge communities of floodplain depressions. According to Indicator Species Analysis, the Ranunculus auricomus was an indicator of management in mesic and wet meadows, Carex cespitosa and Calamagrostis canescens indicated the unmanaged tall sedge and wet meadows respectively.
