Post-translocation development of boreal bog vegetation - results of an experiment in Lusatia.

Abstract

Bogs belong to the most endangered habitats. Opencast mining is one reason of habitat destruction. But can the translocation method help to conserve or spread the rare bog vegetation? This paper describes such a translocation experiment with an opencast mine in Lusatia as a donor site and a pond region in Lusatia as a receptor site. In the year 2005, fragments of the vegetation type Sphagno tenelli-Rhynchosporetum albae Osvald 1923 were translocated from the opencast mine "Nochten" to the receptor site "Trebendorfer Tiergarten". In surveillance plots the moss-coverage decreased from 2005 to 2009, but regeneration was observed until 2012. And herbs decreased between 2005 and 2009 (Rhynchospora alba, Eriophorum angustifolium) or 2005 and 2012 (Andromeda polifolia and Vaccinium oxycoccos). Drosera rotundifolia is actually stable in the translocated vegetation sods, but invasion of Phragmites australis could be a serious problem for the survival of translocated plants. Future observations should show which bog plant species can survive in their new habitat in a long-term perspective.
