“…An increase in species numbers following translocation and some colonisation by weed species was also observed by Worthington and Helliwell () as a result of perturbation of vegetation and soil. However, Standen and Owen () observed that, 6 years after translocation, the vegetation type of the receptor site corresponded to the vegetation of the donor site, whereas Klötzli () observed a labile phase for 5–8 years in plant community composition, followed by stabilisation of vegetation after 10 years. Similar preliminary changes, followed by stabilisation in floristic composition, were observed in other human‐created habitats (Nowak, Wegrzynek, & Tokarska‐Guzik, ).…”

Rapid change in forms of inorganic nitrogen in soil and moderate weed invasion following translocation of wet meadows to reclaimed post‐industrial land

Anthropogenic expansion and loss of natural environments calls for the more sustainable use of resources, including land. To combine the conservation of highly valuable meadow habitat with reclamation of post‐industrial land, 1.3 ha of turf were translocated from an urban area to basins constructed near an abandoned quarry. In contrast to the usual method of choosing similar habitats as salvage sites, the selected quarry possessed different environmental properties to the meadows, challenging their acclimatisation. To evaluate the project, we monitored three meadows (Molinion caeruleae alliance) for three seasons: immediately before the transfer and for 2 years afterwards. We recorded vegetation composition in tandem with 27 physico‐chemical properties of the soil. In the first year following translocation, enrichment of soil in total calcium, potassium, sodium, and sulphur was noted. The contents of available phosphorus, nitrogen, and magnesium, as well as soil pH, were lower in the second year. The domination of ammonia over nitrate, which is characteristic of wetlands, decreased markedly. Water holding capacity slowly decreased as well, suggesting humus decomposition. The plant communities maintained their high level of diversity, and the dominance of characteristic meadow species continued. However, an increase in the number of weeds was observed, along with the replacement of some meadow plant species by others. We conclude that if a receptor site does not resemble a habitat type of a donor site, the ecosystem becomes more human‐dependent and requires site‐specific aftercare. In this case, the active control of competitive and ruderal species invasion and moisture management is required.

“…Examples of invasive behavior after restoration are described by Beltman et al (1995) where Sphagnum species started to dominate the vegetation after sod cutting aimed at restoring basiphilous wetland communities. Klötzli (1987) reported on one of the first large‐scale transplantation experiments in Europe, where mesotrophic fen and fen meadow vegetation was transplanted to an artificially constructed wetland to make room for an airport near Zürich. He found that many native species, which were present in small numbers in the original sward ( Carex hirta [hairy sedge] , Eupatorium cannabinum [hemp agrimony] and several Juncus [rush] species) expanded rapidly after some time.…”

After almost 40 years of experience in wetland restoration in Central Europe in which vegetation changes have been monitored by means of permanent plots or vegetation maps, some light can be shed on the intrinsic dynamics of such ecosystems, showing the limits of restoration and constraints in its manipulation. Sometimes such constraints in the restoration process can be identified, mostly being constraints in nutrient availability or in the water regime, but unexpected changes can also be the result of intrinsic species fluctuations or invasive species. Unexpected vegetation developments are sometimes undesired, can be very persistent and may indicate that environmental conditions are not suitable for target communities. Unexpected developments also illustrate the limits in restoration ecology. Very often the restoration process simply proceeds along successional pathways we did not anticipate. Theories about such alternative pathways can be explored using prediction models, such as cellular automata, which can handle the results of biomonitoring very efficiently. Biomonitoring during 40 years, however, has also shown that a certain amount of unpredictability has to be taken for granted, both in natural wetlands and in areas under restoration.
