Yn sgil y Strategaeth, crewyd dwy ardal reoli - yr Ardal Reoli Graidd (CDZ) lle nad oes gofyn i berchennog y tir dorri na difetha coed o fewn terfyn amser ac Ardal Cyfyngu ar y Clefyd (DLZ) lle bydd gofyn i'r perchennog dorri a difetha coed o fewn terfyn amser i rwystro'r clefyd rhag lledaenu i ardaloedd diglefyd.
The strategy led to the introduction of 2 disease management zones - a Core Disease Zone (CDZ) which does not require land owners to fell/destroy trees within a time limit and a Disease Limitation Zone (DLZ) which does require landowners to fell/destroy trees within a time limit to limit the further spread of the disease into unaffected areas.
