Ym mis Tachwedd 2011, cyhoeddais fy mod am fwrw ymlaen â chreu Un Corff newydd i Gymru drwy dynnu ynghyd swyddogaethau Cyngor Cefn Gwlad Cymru, Asiantaeth yr Amgylchedd Cymru a Chomisiwn Coedwigaeth Cymru.
In November 2011, I announced that I was minded to proceed with creating a new Single Body for Wales by bringing together the functions of the Countryside Council for Wales (CCW), the Environment Agency Wales (EAW) and Forestry Commission Wales (FCW).
