Ar 23 Tachwedd 2010, cyhoeddais fy mod yn sefydlu grŵp annibynnol, gyda ffermwyr o bob cwr o Gymru yn aelodau ohono a than gadeiryddiaeth Rees Roberts, i adolygu Elfen Cymru Gyfan cynllun Glastir, sef y trefniadau fferm gyfan newydd ar gyfer rheoli tir yn gynaliadwy yng Nghymru a fydd yn dechrau yn 2012.  Pwrpas yr adolygiad yw dysgu o rownd gyntaf ceisiadau’r cynllun a gwneud argymhellion i wneud yr opsiynau o dan yr Elfen Cymru Gyfan yn fwy deniadol i’r gymuned ffermio.  Fel y dywedais ar y pryd, doeddwn i ddim am adolygu egwyddorion sylfaenol y cynllun na’r canlyniadau amgylcheddol y mae’r cynllun yn ceisio eu gwireddu.
On 23 November 2010 I announced the setting up of an independent group, made up of farmers from across all of Wales, and chaired by Rees Roberts, to review the All-Wales Element of the Glastir scheme, the new arrangements for farm-based sustainable land management in Wales that is to become operational in 2012. The purpose of the review was to capture practical learning from the first round of applications to join the scheme and to make recommendations to enhance the attractiveness of actions under the All-Wales Element to the farming community. As I made clear at the time, the underpinning principles and stated environmental outcomes sought from the scheme were not under review.
