Metadata: Saltmarsh Features at Cefni and Aberffraw 1998
Abstract:
This dataset contains the results of a survey which used the National Vegetation Classification (NVC) as a basis for community definition in the saltmarsh habitats of Anglesey (Cefni and Aberffraw). The purpose of this data capture is to use the National Vegetation Classification to describe and map areas of saltmarsh on the southern shore of Anglesey that were put forward as a potential Special Area of Conservation (pSAC) as part of the Glannau Mon: Cors Heli/ Anglesey Coast saltmarsh.

| Internal code | Internally assigned metadata identifier | 8632 |
| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | Saltmarsh Features at Cefni and Aberffraw 1998 |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | NRW_DS109861 |

| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | dataset |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 1998-08-16 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 1998-10-17 |
| Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | notPlanned |
| Abstract | The abstract provides a clear and brief statement of the content of the resource. | This dataset contains the results of a survey which used the National Vegetation Classification (NVC) as a basis for community definition in the saltmarsh habitats of Anglesey (Cefni and Aberffraw).

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Standard NVC survey methodology was used. Data collected by trained personnel, digitised by contractors, validated by CCW KMG, corrections made by contractors, validated again by CCW KMG, corrections made in-house in conjunction with relevant salt marsh specialist. CCW commissioned survey which contributes to an NVC Phase 2 Saltmarsh survey collation (see 'part of' field). |
