Re-vegetation processes in cutaway peat production fields in Estonia in relation to peat quality and water regime

摘要: Eighty-one cutaway peat production fields with a total area of about 9000 ha exist and were studied in Estonia 2005-2015. Only very small number the (seven) have been restored-either afforested or used for growing berries. The re-vegetation Estonian is mainly result natural processes, which are generally slow due to an unfavourable water regime too thin remaining layer. mostly covered by cotton grass birches. Often sparse vegetation covers 15-20% field, but some turned into heaths grasslands plant coverage up 60%. However, changes environmental (mainly hydrological) conditions characteristics type), these areas can also be new niches several species. A moss species rare Estonia, e.g. Pohlia elongata, Ephemerum serratum, Campylopus introflexus Bryum oblongum, recorded.
