Cyfnod 2 Arolwg o Dwyni Tywod yng Nghymru
Mae hon yn set ddata ofodol sy'n cynnwys casgliad o'r holl gynefinoedd twyni tywod sydd wedi'u mapio yng Nghymru. Cynhaliwyd dros 40 o arolygon Dosbarthiad Llystyfiant Cenedlaethol Cyfnod 2 ar dwyni tywod ledled Cymru. Casgliad o ddata o'r arolygon hyn yw'r set ddata hon, wedi'u cyfuno at ddibenion symudiadau ac i ddarparu gwybodaeth ar raddfa Cymru gyfan. Diben y data hwn a gasglwyd oedd helpu i ddiffinio adnoddau llystyfiant twyni tywod Cymru. Gall cyfansoddiad cynefinoedd newid dros amser o ganlyniad i dueddiadau olynol, rheolaeth tir neu hyd yn oed ddatblygiadau arfaethedig. Felly, ni ellir bod yn sicr bod math o lystyfiant neu rywogaeth yn parhau i fodoli am ei fod wedi'i gofnodi yn y data digidol.

The field surveys utilised standard Phase 2 survey methodology. Vegetation mapping and community definition followed the National Vegetation Classification (NVC). For each site surveyed a vegetation map (scale of 1:7500) was produced which was later digitised.
