Mi wnaeth Duncan, Twm a Bruce waith dan gontract yn ddiweddar iawn i benderfynnu termau ar gyfer nifer fawr o gynefinoedd a rhestrir yn y Dosbarthiad Llystyfiant Cenedlaethol (NVC):

Dyma fi eto.

 

A oes gwahaniaeth pendant rhwng y ddau air hyn yn y Gymraeg?

 

Mae'r dewisiadau a gynigir yn debyg iawn yn y geiriaduron.

 

A bog is a wetland type that accumulates acidic peat, a deposit of dead plant material.

A marsh is a type of wetland, featuring grasses, rushes, reeds, typhas, sedges, cat tails, and other herbaceous plants (possibly with low-growing woody plants) in a context of shallow water.

A marsh is different from a swamp, which has a greater proportion of open water surface, which is generally deeper than a marsh

A bog can be referred to as a swamp while a marsh technically can not. Also the acidic waters of a bog distinguish it as being different than a marsh. 

 

 

Diolch
