Regional stability versus fine scale changes in community composition of mesotrophic grasslands over 25 years

Long-term studies of vegetation change in grasslands are important to our understanding of the ecology and management of grassland systems, especially for grasslands of high conservation value which have seen a drastic decline due to agricultural intensification and abandonment. This study investigated change over 25 years in 35 mesotrophic grassland sites which were described as species-rich at the start of the study period. Some sites had been...
