These sites have been divided into management units. This dataset contains the boundaries of these units and includes information such as designation type, unit name, unit area, national grid reference and former Countryside Council for Wales (CCW) regions. Digitising began in 2007 and is on going as and when new sites are created or existing sites are altered. The purpose of these management units is to have a coherent plan in order to manage sites in a practical manner to ensure that work is done to get sites and their corresponding features into a favourable condition, as per the requirements of the protected sites.

Mae safleoedd dynodedig yng Nghymru yn cynnwys, ond heb fod yn gyfyngedig i, Safleoedd o Ddiddordeb Gwyddonol Arbennig (SoDdGA), Ardaloedd Gwarchodaeth Arbennig (AGA), Ardaloedd Cadwraeth Arbennig (ACA) a safleoedd Ramsar. Caiff y safleoedd hyn eu rhannu'n unedau rheoli. Mae'r set ddata hon yn cynnwys ffiniau'r unedau hyn, ynghyd â gwybodaeth am y math o ddynodiad, enw'r uned, arwynebedd, cyfeirnod grid cenedlaethol a hen ranbarthau Cyngor Cefn Gwlad Cymru (CCGC). Dechreuodd y gwaith digido yn 2007, ac maen dal i ddigwydd pan gaiff safleoedd newydd eu creu neu eu haddasu. Pwrpas yr unedau rheoli hyn yw cael cynllun cydlynol fel y gellir rheoli safleoedd mewn modd ymarferol er mwyn gwneud yn siŵr fod gwaith yn cael ei wneud i sicrhau bod y safleoedd a'u nodweddion cyfatebol mewn cyflwr ffafriol, yn unol â gofynion y safleoedd gwarchodedig.

The data is then cleaned and entered into Oracle Spatial. When new protected sites are designated, or existing sites are amended, there can be a lag time for when the unitisation layer is updated to reflect the latest changes. Therefore this layers should not be used as the definitive source for showing protected site boundaries.
