Extinct moss refound on Clara bog

George Smith has made a great discovery on Clara Bog, he recently found a small population of waved fork-moss (Dicranum undulatum), a plant up until then thought to be extinct in Ireland.  It was previously known from only four other raised bogs in Offaly.  Last seen in Ireland in 1960, its known sites have been seriously damaged by peat harvesting.  The sites and other raised bogs in Offaly that were in reasonable condition were searched fruitlessly for the plant over 2005-2009.  Because the only known populations could not be found again and because of the damage caused to raised bogs in the area due to turf cutting, waved fork-moss was judged to be extinct in Ireland in the recent book on the Rare and Threatened Bryophytes of Ireland.
