Bydd afancod yn helpu adferiad byd natur yng Nghymru!
Mae afancod yn anifeiliaid arbennig iawn oherwydd eu bod yn chwarae rhan hanfodol wrth adfer a rheoli ecosystemau afonydd a gwlybdiroedd. Mae hyn yn creu cynefinoedd amrywiol i rywogaethau eraill ffynnu, gan fod o fudd i amrywiaeth eang o anifeiliaid a phlanhigion eraill. Cyfeirir yn aml at afancod fel 'rhywogaeth allweddol' neu 'beirianwyr byd natur' oherwydd yr effaith gadarnhaol y gallant ei chael ar yr amgylchedd.
