Pa asesiad mae'r Gweinidog wedi'i wneud o (a) faint o garbon sy'n cael ei storio fesul hectar o fawn dwfn, a (b) faint o'r carbon hwn sy'n cael ei golli pan fydd coed yn tyfu ar fawn dwfn o ganlyniad i ddiffyg rheolaeth, cynlluniau dad-ddofi tir, neu gael eu plannu?

- >63,865 kt of carbon is estimated to be stored in Welsh peatlands. A per hectare estimate cannot be provided due to the inherent variation in peat depth. The Welsh Peatland Data Portal | Wales Environmental Information Portal (arcgis.com) provides carbon stock estimates. Further information on its production and how estimates are calculated may be found in the Soil Policy Evidence Programme 2020-21: Production of the Peatlands of Wales Map (gov.wales)
- The amount of stored carbon lost due to any land use activity will depend on the level of disturbance, alterations to hydrology, period of use, and management activity. Section 2.3 of the National Peatlands Action Programme, 2020-2025 (cyfoethnaturiol.cymru) document provides further information on the pressures and condition of Welsh peatlands. Table 4.1 of the Implementation of an Emissions Inventory for UK Peatlands (defra.gov.uk) is used to assess emissions.
