Cyfnod 2 Arolwg o Fawndiroedd yr Iseldir yng Nghymru
Roedd y set ddata hon yn rhan o arolygon cynefinoedd Cyfnod 2 a gynhaliwyd ledled Cymru. Mae'n cynnwys arolwg manwl o gymunedau planhigion yn llystyfiant mawndiroedd yr iseldir. Prif nod yr arolwg yw nodi a gwerthuso'r llystyfiant sydd ym mawndiroedd iseldir Cymru er mwyn sicrhau bod safleoedd mawndir pwysig yn cael eu nodi, eu diogelu a'u rheoli. Mae'r holl set ddata wedi'i chadarnhau a'i dilysu'n drwyadl gan arbenigwyr arolygu llystyfiant Cyfoeth Naturiol Cymru. Gall cyfansoddiad cynefinoedd newid dros amser o ganlyniad i dueddiadau olynol, rheolaeth tir neu hyd yn oed ddatblygiadau arfaethedig. Felly, ni ellir bod yn sicr bod math o lystyfiant neu rywogaeth yn parhau i fodoli am ei fod wedi'i gofnodi yn y data digidol.

This dataset contains spatial sites and species data, non-spatial species data and images in JEPG and slide format. Phase 2 vegetation mapping and collection of quadrat data on plant community composition. Additional information is collected on notable species, peat depth, environmental factors, condition, management requirements and conservation evaluation. See Lowland Peatland Survey of Wales Survey Manual Version 2, S.D.S. Bosanquet et al., 2023 (In Prep.) for more information.
Written site accounts are available for each surveyed site. These greatly assist in interpreting the raw data in each case. Characterise and evaluate the vegetation cover of lowland peatlands in Wales based upon a programme of plant (sub-) community level sampling and mapping. All Wales, underpinned by criteria to aid site selection.
The current survey programme is the latest in a series of Phase 2 level surveys of major habitat groups in the Welsh lowlands. These include the recently completed Lowland Grassland Survey, which was undertaken in-house, and commissioned surveys covering lowland heathlands, woodlands, sand dunes and saltmarsh. The current peatland survey programme follows on an earlier pre-NVC assessment conducted between 1977 and 1982 (the Welsh Lowland Peatland Survey) which is dated and inadequate for modern conservation practice. This is the concluding part of a strategic series of Phase 2 level survey programmes across Wales.
Entire dataset has been extensively validated and verified by NRW vegetation survey specialists. Habitat composition may change over time due to successional trends, land management or even planned developments. A record of a vegetation type or species in the digital data is therefore no guarantee that it is still extant on the ground. Bosanquet, S.D.S., Jones P.S., Reed D. K., Birch K.S. & Turner A.J. 2022.. NRW Evidence Report No: [XX], [XX]pp, Natural Resources Wales, Bangor In Prep.

Part of this dataset (habitat data) has no access restrictions and NRW may release, publish or disseminate it freely. However part of this dataset is sensitive and restricted as it contains data exempt from general release. The sensitive data is as follows; 1) Plant species listed on the NRW Sensitive Species List. This may only be released at a scale 10km sq. 2) Personal data e.g. names and addresses, other personal details. This information will not be released without permission of those involved 3) Sensitive site data, e.g. information about a site prior to designation. 4) Data with a landowner interest e.g. if a landowner specifically objects to information about their property being released Sensitive data must be kept confidential; general release is not permitted due to risk of harm to the environment or third parties.
