Ymatebodd Llywodraeth Cymru’n gyflym i roi’r Ddeddf ar waith ar ôl i Awdurdodau Lleol, elusennau ceffylau a’r Heddlu alw am gamau brys i fynd i’r afael â phori anghyfreithlon a cheffylau a merlod yn crwydro ac yn cael eu gadael ledled Cymru. Mae’r Ddeddf yn rhoi pwerau cyfreithiol i Awdurdodau Lleol yng Nghymru fynd i’r afael â phori anghyfreithlon.
The Welsh Government acted quickly to introduce the Act in response to calls for urgent action by Local Authorities, equine charities and the Police to tackle the problem of fly grazing, straying and abandonment of horses and ponies across Wales.  The legislation provides Local Authorities in Wales with consistent legal powers to address issues connected with fly grazing.
