Rydym yn monitro effaith yr holl bolisïau ac ymyriadau hyn ledled Cymru, ond mae gennym y cynllun peilot yn Nwyfor hefyd, ble rydym yn gweithio'n agos gyda chymdeithasau tai Cyngor Gwynedd, Parc Cenedlaethol Eryri, Grwp Cynefin ac Adra, a chymunedau lleol i gyflwyno a gwerthuso'r mesurau hyn. Dewiswyd yr ardal oherwydd ei maint daearyddol, y crynodiad o ail gartrefi a'r effaith ar y Gymraeg.
We are monitoring the impact of all these policies and interventions across Wales, but we also have the pilot in Dwyfor, where we are working closely with Cyngor Gwynedd, Eryri National Park, Grwp Cynefin and Adra housing associations, and local communities to introduce and evaluate these measures. The area was chosen because of its geographic size, the concentration of second homes and the impact on the Welsh language.
