Plant regenerative strategies after a major disturbance: The case of a riverine wetland restoration

Soil seed banks of two montane riparian areas: implications for restoration

“…Also, description of the seed bank species composition provides an indication of the type of community that could develop, depending on environmental changes at the site (Leck et al 1989). Seed banks can persist at degraded sites, and serve as a re-colonization source for some subset of species, upon restoration of processes or removal of stressors (Rossell and Wells 1999;Combroux et al 2002). Finally, donor seed banks offer potential as a tool in restoring extirpated plant species to riparian floodplains, similar to their role in restoring various types of degraded wetlands (van der Valk et al 1992;Brown and Bedford 1997;Burke 1997).…”

Re-establishment of an extinct population of the endangered aquatic plant Potamogeton coloratus

“…Whereas monitoring vegetation cover can serve as one measure of ongoing success, important information on longterm success can come from monitoring soil seed banks over time (e.g. Combroux et al, 2002;Neff et al, 2009;Diggory and Parker, 2011). In general, production of dense soil seed banks by the target species in restored wetlands is a basic requirement for the species' further survival in case of temporarily unsuitable conditions (Baskin and Baskin, 1998;Fenner and Thompson, 2005).…”

“…It can be especially important for extremely rare species that are extinct over large areas, with soil propagule bank activation providing the last realistic possibility for population recovery. Soil propagule banks can be used both for restoration in situ (Brouwer et al, 2002;Combroux et al, 2002;Nishihiro et al, 2009), by exposing the necessary sediment layers, or they can be transported to recolonize other suitable sites (Brown and Bedford, 1997).…”

Resprouting Response of Aquatic Clonal Plants to Cutting May Explain Their Resistance to Spate Flooding

“…Because aquatic plants may propagate by fragment dispersal (Cellot et al 1998;Boedeltje et al 2004), vegetative regeneration may be a key function for the maintenance of these species in these ecosystems (Abernethy and Willby 1999;Combroux et al 2002). The aim of the present work was to investigate the effect of mechanical disturbances on aquatic plant survival and regrowth.…”
