Pwrpas y newidiadau hyn yw diogelu bioddiogelwch a chefnogi masnach rhwng Prydain Fawr a thrydydd gwledydd trwy wella mesurau amddiffynnol ar gyfer nwyddau planhigion mewn perygl.
The purpose of these changes is to protect biosecurity and support trade between Great Britain (GB) and third countries by enhancing protective measures for at-risk plant goods.
