“…This is an effective mechanism to tolerate desiccation, but metabolism (photosynthesis, growth) can only occur when water is available and the plant is hydrated (Proctor, 2000;Robinson et al, 1989). Several studies have shown that atmospheric water availability is more important to bryophytes than the moisture level of the soil because bryophytes absorb water with their entire above-ground surface (Graf and Rochefort, 2010;Klepper, 1963). We found a positive relationship of soil moisture with soil bryophyte abundance and species richness.…”

“…in a 10-km square), but also local climate and habitat conditions, as these determine the survival and establishment of the transplants (Gunnarsson and Söderström 2007;Graf and Rochefort 2010). In this study, transplanted bundles of shoots grew independent of microhabitat type, only a very small negative influence of cover of grasses on growth was indicated.…”

“…However, transplanted fragments of H. hutchinsiae have been shown to grow better between other bryophytes than in other microhabitats (Flagmeier et al 2013). Graf and Rochefort (2010) similarly reported an effect of microhabitat on transplants of Sphagnum with fragments regenerating better under a dense canopy of herbaceous plants. Hence, even if vegetation type were not critical for population persistence, the success of fragment establishment and growth, and therefore population expansion, may be influenced by the surrounding vegetation.…”

Background: Translocating plants for conservation purposes can be a useful tool to enhance existing populations, restore lost populations or create new ones, but has rarely been done for bryophytes, especially liverworts. Aims: Here, the leafy liverwort Herbertus hutchinsiae, a representative species of oceanic-montane liverwort-rich heath, was translocated to unoccupied habitat within its current range, to establish whether its restricted distribution is due to habitat or dispersal limitation. Methods: Feasibility of establishing new populations outside the current distribution range was assessed, to test the suitability of the species for assisted colonisation. Furthermore, transplants were grown at degraded sites where the species had declined to assess potential for restoration. Results: Although maximal growth rates occurred within-range, transplants grew at all sites, indicating that the species could be dispersal limited; a conclusion supported by distribution modelling. Conclusions: Assisted colonisation is thus an option for this species to overcome dispersal limitation and to track future climate space. Reinforcement of populations at degraded sites is only recommended if the pressure causing the degradation has been removed. These findings provide an evidence base for practical conservation management.

1.Reclaiming peatland ecosystems is challenging our understanding of how to rebuild functioning landscapes. Assisted succession may provide a practical approach to guide the reestablishment of peatlands in denuded landscapes. In Alberta, the majority of peatlands began as fens during the paludification process. This research focuses on creating fen initiation conditions to establish fen moss species on mineral sediment as an approach for peatland reclamation in the oil sands region. 2. In a field mesocosm experiment, we evaluated the establishment of five common fen mosses (Drepanocladus aduncus, Ptychostomum (Bryum) pseudotriquetrum, Campylium stellatum, Tomentypnum nitens and Aulacomnium palustre) introduced in equal proportions to clay loam. To determine the optimal hydrologic conditions for the establishment of each species, we tested four water levels (0, À10, À20 and À30 cm). We created vegetation types similar to those identified at the peat-mineral interface in peat profiles to determine the effect of herbaceous plant, low shrub and wood-strand mulch cover treatments on moss establishment. 3. Three seasons after introduction, total moss cover averaged 40% and was greatest under all cover treatments and at the 0 cm water level. Total moss biomass averaged 95Á5 g m À2 in moss introduction mesocosms and was greatest under low shrubs and herbaceous plants and at the 0 and À30 cm water levels. Fen moss species distribution was significantly influenced by water-table depth. Drepanocladus aduncus and Ptychostomum pseudotriquetrum were most common at 0 cm and Aulacomnium palustre and Tomentypnum nitens at À30 cm. 4. In this approach, we created vegetation types similar to those found on mineral sediments at the base of Alberta peat cores and successfully established distinct fen moss communities along a water-table gradient and under shade cover. Introducing a suite of fen moss species that inhabit a range of hydrologic niches under low shrubs or herbaceous plants improves moss establishment. 5. Synthesis and applications. Our research shows that it is possible to create fen initiation conditions on clay loam sediment by introducing foundation moss and vascular plant species at optimal water levels. Restoring the community structure and biomass accumulation that occurs in the initial stages of fen development appears to be a suitable target for peatland reclamation. These methods introduce a practical strategy to reclaim peatlands in the heavily impacted oil sands region of Alberta.
