Aeth Hannah Blythyn i ymweld â Choedwig Clocaenog, sy’n cael ei rheoli gan Cyfoeth Naturiol Cymru, i ddod i wybod mwy am y gwaith cadwraeth sy’n digwydd yno.  Mae wiwerod coch yn brin yng Nghymru.  Yn ogystal â Choedwig Clocaenog, mae rhagor o wiwerod i’w gweld ar Ynys Môn ac yn y canolbarth.
Hannah Blythyn paid a visit to Clocaenog Forest, managed by Natural Resources Wales, to find out more about the red squirrel conservation work taking place there. Red squirrels are rare in Wales. In addition to Clocaenog Forest, other populations are found on Anglesey and in mid-Wales.
