From Pathfinder Wiki
Succession is where one community naturally changes over time eventually being replaced by a different community. Fens and bogs are often found close together and over time, most fens become bogs. Peat builds up and separates the fen from its groundwater supply causing a closed system to form; nutrient levels drop, acidity increases and a bog is formed. Succession of bogs leads to the formation of conifer forests.
