Mae’r rhan fwyaf o geisiadau yn y broses yn gofyn am gael ailgategoreiddio rhostir ond caiff ceisydd ofyn am ailgategoreiddio tir yn y rhanbarthau talu eraill hefyd.  Mae rhyw ychydig wedi gofyn am ailgategoreiddio tir Dan Anfantais Fawr (ADAF) yn Dir Arall, y rhanbarth sy’n talu fwyaf.  Bydd p’un a ddylid caniatáu newid categori tir yn dibynnu ar botensial y tir i gynhyrchu.  Am hynny, yn unol â rheolau Llywodraeth Cymru, dim ond aelodau Cymdeithas Ganolog y Priswyr Amaethyddol neu Sefydliad Brenhinol y Syrfewyr Siartredig gaiff paratoi adroddiadau asesu ar gyfer ailgategoreiddio tir ADAF fel rhan o gam 2 y Broses Adolygu Technegol. Mae gan aelodau’r cymdeithasau hyn y sgiliau a’r wybodaeth sydd eu hangen i baratoi adroddiadau o’r fath.  Mae undebau’r ffermio a chymdeithasau rhanddeiliaid yn cefnogi hyn.
The majority of cases submitted to the process have been seeking reclassification of moorland but a claimant may seek reclassification of land in the other payment regions too.  A small number have asked for land classified as Severely Disadvantaged Area to be reclassified as Other Land, the highest paying payment region.  Judgment of whether these cases should be agreed depends on evaluating the land’s potential to produce.  For this reason the Welsh Government will require reports seeking reclassification of SDA submitted for stage 2 of the Technical Review Process, to be prepared by a member of the Central Association of Agricultural Valuers or the Royal Institution of Chartered Surveyors.  Members of these bodies have the appropriate skills and knowledge to prepare reports for claimants.  The farming unions and stakeholder bodies support this approach.
