Figure 5.1 Models describing stages 1A to 5 in secondary retrogressive succession (land-use intensification), and
stages I to IV for secondary progressive (abandonment) succession on seres A, B, and C on fen sites. The initial
stages of the abandonment seres differ in drainage and land-use intensity. The phytosociological units are: Alnion
glutinosae (alder carrs), Magnocaricion elatae (tall sedge reeds), Scheuchzerio-Caricetea (small sedge reeds),
Molinietalia (wet meadows), Lolio-Potentillion (wet pastures).
