Ardaloedd Adfer Posibl ar gyfer Wystrys Brodorol
Datblygwyd y set ddata hon er mwyn canolbwyntio ar ardaloedd adfer wystrys lle mae'r amodau'n addas. Fe'i datblygwyd fel rhan o Gynllun Gweithredu Wystrys Brodorol Cymru.
Mae'r set ddata yn adeiladu ar waith a wnaed gan ABPMer i Cyfoeth Naturiol Cymru (CNC) ynghyd â gwaith ychwanegol gan CNC. Mae'n set ddata gyfansawdd o baramedrau ffisegol addas a chynefin addas i wystrys fyw ynddo. Mae hyn yn cynnwys ynni cyfredol <130nm-2, dyfnderoedd dŵr o dan 80m a gwaddodion is-lanwol cymysg, bras neu wedi’u domiynyddu gan facroffytau. Ychwanegwyd ardaloedd y glannau lle roedd yr haenau mewnbwn model yn rhy fras ac ystyriwyd bod yr ardaloedd yn addas gan arbenigwyr CNC.
Mae ffynonellau data yn cynnwys EMODNet (ynni cyfredol), GEBCO (bathymetreg y DU) a map cyfunol JNCC UKASH.

This is a composite dataset of suitable physical parameters and suitable habitat for oysters to live. This includes current energy <130nm-2, water depths of under 80m and subtidal mixed, coarse or macrophyte dominated sediments. Inshore areas were added where the model input layers were too coarse and the areas were considered suitable by NRW specialists.
Sources of data include EMODNet (current energy), GEBCO (UK bathymetry), JNCC UKASH combined map.

Part of this dataset is sensitive, and access may be restricted under relevant legislation. The sensitive data is the exact location of existing native oyster records. NRW may NOT publish or disseminate the sensitive data. Requests should be referred to NRW's Access to Information Officer. However, there are no access restrictions on non-sensitive data. NRW may release, publish or disseminate a redacted version of the data freely.
