Ym mis Mawrth mae Tinwen y Garn yn dechrau dychwelyd i Gymru ar gyfer y tymor magu. Mae'r aderyn lliwgar yma, sydd yr un maint â Robin Goch, ar y rhestr Oren yng Nghymru; mae wedi profi dirywiad cymedrol ledled y DU ers 2010.

We're delighted that Welsh Government has brought clarity for farmers about the Universal Layer of the upcoming SFS but the scheme’s ambition doesn’t match up with the resources needed to drive change for nature. Wales is at risk of failing to meet international commitments.
