Mae oddeutu 7,000 o ffermwyr yn ddeiliaid cytundeb Tir Gofal neu Tir Cynnal. Yn dilyn y trefniadau i estyn y cytundebau hyn tan 2014, bydd llawer o’r ffermwyr hyn yn aros cyn ystyried ymuno â Glastir. Ychydig dros 10,400 o ffermwyr sydd wedi hawlio’r taliad Tir Mynydd olaf, a wneir ym mis Mawrth 2012. O’r rheini, mae oddeutu 5,000 wedi mynegi diddordeb mewn ymuno ag Elfen Cymru Gyfan Glastir o 2013 ymlaen.
Approximately 7,000 farmers hold a Tir Gofal or Tir Cynnal agreement. Following the extension arrangements, many of these farmers will not consider entry to Glastir until 2014 when their extension arrangements come to an end. Just over 10,400 farmers have claimed the final Tir Mynydd payment which will be made from March 2012. Of these, approximately 5,000 have expressed an interest in joining the Glastir AWE from 2013.
