“…Other cases of rapid vegetation change in fens throughout Europe have been shown to be related to human influences, such as changed hydrology and increased deposition of acidifying and eutrophicating compounds (Zoller & Selldorf ; Hogg et al. ; Hedenäs & Kooijman ; Bobbink et al.…”

“…For example, Polytrichum uliginosum is reported as an invasive in acidifying fens in the Netherlands, but this species is much more rare in reports from other regions (O'Connell ; Gorham et al. ; Zoller & Selldorf ; Hogg et al. ; Hedenäs & Kooijman ; Gunnarsson et al.…”

“…Examples of such studies have shown considerable floristic changes, notably in the second half of the 20th century. These changes were often linked to environmental changes, such as desiccation and increased nitrogen deposition (Zoller & Selldorf ; Kooijman ; Gunnarsson et al. , ; Limpens et al.…”

Nomenclature Dirkse et al. (1999) for bryophytes (except Polytrichum); Van der Meijden (1996) for vascular plants; Schamin ee et al. (1995b) for syntaxa; We use Polytrichum uliginosum (Wallr.) Schriebl (Bijlsma et al. 2000) as distinct from P. commune Hedw.Abstract Question: How did frequency and local abundance of key bryophytes in Dutch fens change between 1940 and 2000? Location: The Netherlands.Methods: A total of 1939 vegetation relev es, objectively assigned to the class Parvocaricetea and dating from the period 1940-1999 inclusive, were extracted from a national Netherlands database. From this relev e set, two additional data sets were derived; these were syntaxonomically homogeneous at the association level. One contained 418 Scorpidio-Caricetum diandrae relev es and the other 956 Pallavicinio-Sphagnetum relev es. The following analyses were done for these three data sets: frequency and local abundance change of 13 bryophyte species over three 20-yr periods were described using logistic regression and the nonparametric Jonckheere-Terpstra test, respectively.Results: Acidophytic, late-successional species, notably Sphagnum palustre and Polytrichum uliginosum, have replaced relatively early-successional species such as brown mosses, Sphagnum subnitens and Sphagnum squarrosum during the studied period. The results were mostly consistent across the three data sets. Local abundance patterns generally paralleled those of frequency, although cover trends were often less robust. Conclusions: Drastic changes have taken place in the bryophyte layer ofDutch fens between 1940 and 2000. Our study has shown that acidophytic, late-successional bryophytes have replaced relatively early-successional brown moss and Sphagnum species. Both hydrological changes and nutrient shifts (in particular phosphorus enrichment and ammonium toxicity) appear to have been responsible for the observed rapid shifts in the bryophyte layer of Dutch fens.Additional supporting information may be found in the online version of this article:Appendix S1.
