Original Title |
National Water Vole Monitoring Programme (NWVMP) |
Temporal Coverage Notes |
The NWVMP started in 2015 and is ongoing. Most surveys take place in May and should have a full date (DD/MM/YYYY). Some sites are surveyed again later in the summer (September/October). |
Module Description |
Records from the Cofnod area (2020) |
Purpose |
Data are collected for the purpose of producing population trends. |
Capture Methods |
One bank of a 500m stretch of waterway is surveyed to record all water vole field signs (latrines, feeding signs, burrows and sightings) within each 100m section. Sites are either ones that were surveyed in the previous national water vole surveys carried out by The Vincent Wildlife Trust (VWT) or have been registered with the programme. Most transect are 500m, but some sites have multiple shorter transects (i.e. 100m) surveyed. Normally one survey is carried out during May but some sites are surveyed again later in the summer. All volunteers are asked about their experience of surveying when registering to take part and photos of signs can be submitted to allow verification. |
Verification/Validation Procedures |
All data were collected using a standardised method. Participants are provided with training and resources to aid identification of the field signs but it is not possible to verify all records from this survey. Volunteers are encouraged to submit photos of field signs so they can be verified and the experience of the monitor is establish during the registration process. It is also recommended that volunteers gain some practical experience of surveying for water voles before taking part. The data do not represent a complete picture of water vole distriution but should be considered as a sample of sites from across England, Scotland and Wales. The dataset has been checked using NBN Record Cleaner. |
