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.

Global governments are coming together once again for COP27 (or the 27th Conference of the Parties) to discuss climate change and the commitments each country will make to adapt and reduce carbon emissions. A year on from COP26 in Glasgow little progress has been made and time is running out to avoid catastrophic global warming.

The Wildlife Trusts want to see the bold rhetoric and ambitions translated into real action this decade to tackle the twin nature and climate crises.

Only a 20 minute boat trip from the mainland, Skomer is an excellent place for a daytime adventure. Bursting with seabirds including our Atlantic Puffins, Guillemots and Razorbills, this National Nature Reserve is one of Britain's most important seabird colonies. It is peaceful and wild at all times of year - there's so much to see and explore.

Please note, Puffins start arriving in mid-April. They are present from May-July. The first ones start leaving in mid-July and all Puffins are gone by the end of July. Please see our seasonal timeline below for what to see each month.
