Peat extraction leads to the formation of areas with altered habitat conditions in comparison to natural peatlands. Restoration of the peat-formation process in these areas is very difficult and requires the creation of suitable conditions for the growth of peatland species. The aim of the study was to analyse the habitat requirements of bryophytes...

... total 42 species of bryophytes were identified (Table 1). on the species composition of bryophytes showed that the factors with a significant impact were hydrological parameters (minimum, maximum and average water level), shade, physical parameters of the peat (proportion of macropores) and its chemical parameters (carbon content and C/N ratio) ( Table 2). The use of the forward selection procedure (conditional effect) in the RDA showed that for the occurrence of bryophyte species the deciding factor was the average water level, but a statistically significant increase in the percentage of variation explained was obtained by also taking into account parameters of the peat such as the proportion of macropores, carbon content, and pH in KCl. ...Similar publications
Understanding large‐scale drivers of biodiversity in palustrine wetlands is challenging due to the combined effects of macroclimate and local edaphic conditions. In boreal and temperate fen ecosystems, the influence of macroclimate on biodiversity is modulated by hydrological settings across habitats, making it difficult to assess their vulnerabili...

... Some small-scale studies (Mälson and Rydin, 2007;Graf and Rochefort, 2010) demonstrated the regeneration potential of brown mosses, and in our case, the active reintroduction of fen plants by mechanical transfer led to a species composition similar to the regional natural fens. However, the regeneration of peatland plant communities remained limited because of the drier nature and low water table of the sector, as proposed by the same studies and Zarzycki et al., 2022. Meanwhile, it is worth noting that the success of the vegetation trajectory cannot solely be determined by species similarity but by the successional development of the site's stable biotic and abiotic conditions towards a desired ecological state. ...
... The REW sector showed an increased frequency of marsh-swamp species, but it did not affect the bryophytes as much as the passive regeneration in the UNR sector due to the persistent high-water table or no dryness throughout the sector (Graf and Rochefort, 2010;Zarzycki et al., 2022) and relatively low frequency of tall trees and shrub species. Due to the location of the BSF site, particularly the REW sector in a low topographic area with underlying gyttja (Malloy and Price, 2014; 2017), A.S. Khan et al. ...
... Pre-restoration surveys in the REW + PRO+PLANT sector revealed an extremely low frequency and richness of all habitat-specific categories due to the relatively recent extraction history, and the acidic, and dry nature of this sector (Cooper and MacDonald, 2000;Girard et al., 2002;Lavoie et al., 2003Lavoie et al., , 2005aLavoie et al., , 2005bGagnon et al., 2018) but the active reintroduction somewhat marginally favored it. During the post-restoration surveys, we observed a prominent difference in the vegetation composition of the REW + PRO+PLANT sector, and it appears to be on a trajectory closer to the regional natural fen's species composition, suggesting it may be more effective in achieving a similar ecological state to the natural fen if the treatment is applied in presence of adequate environmental conditions (Price and Whitehead, 2000;Zarzycki et al., 2022). However, in our case, we do not expect that the REW + PRO+PLANT sector will eventually go on a trajectory similar to the surrounding natural fens because of its drier nature, and thus, corrective measures of restoration should be applied (Quinty and Rochefort, 2003). ...
The peatland restoration method, the Moss Layer Transfer Technique (MLTT), has been successfully developed and implemented to restore Sphagnum-dominated peatlands in North America. The efficiency of an adapted version of the MLTT using fen plants for minerotrophic (fen) peatland restoration has shown mixed results, especially regarding the recovery of bryophytes. Additionally, due to differences in peat extraction histories, disturbances, restoration techniques, and desired ecological outcomes, European approaches cannot be directly applied to North American peatlands. It has been suggested that active rewetting alone could ensure fen plant regeneration post-restoration. As there is a growing interest in the minerotrophic peatland restoration, fen restoration methods after peat extraction needs to be refined, and the management process stands in need of new approaches. This study presents the first case of an ecosystem-scale fen restoration project in Canada at an industrial peat extraction site. It was restored in the province of Quebec in 2009, testing three different restoration approaches, including active rewetting only-REW, active rewetting, and peat profiling with vegetation removal-REW + PRO, and a combination of active rewetting, peat profiling with vegetation removal, plus mechanical reintroduction of fen plant material (MLTT)-REW + PRO + PLANT. This study aims to compare the pre-and post-restoration (13 years) plant communities using a BACI design (Before and After Control Impact). It focuses on the recovery of bryophyte carpets and evaluates the return of fen species as well as peatland generalists, marsh-swamps, and upland species. At the whole site level, the rewetting action had a prominent impact and major success in terms of an increase in the richness and frequency of peatland vascular plant species, but the recruitment of peatland bryophytes and particularly brown mosses was relatively much less successful. Active rewetting proved relatively practicable compared to the other two restoration methods, but to enhance its efficiency , it should not result in flooding, which could subsequently lead to helophytisation. The different vegetation outcomes of the restoration were influenced by governing factors such as processes associated with restoration methods (e.g., rewetting, pre-existing vegetation removal, and donor material reintroduction) and site-specific physio-chemical and environmental conditions. Our 13 years post-restoration surveys highlight that there are still large knowledge gaps and that increased, robust research into fen restoration is needed.
