Water vole distribution within Broadland (2003-2006): based upon field signs, sightings and trapping data.
Each record indicates that water voles are present at a given grid reference. They are either a direct sighting or indirect in the form of a latrine or feeding station being present. For the purpose of this data set both direct and indirect are termed as a positive field record.
The dataset has a geographic extent of the Norfolk and Suffolk Broads. No data is provided for urban areas or where BFAP works have not taken place.
Records comprise detailed locations of field signs, incidental sightings and animal captures for translocation purposes. Survey data is used to assess the environmental impact of individual schemes, plan mitigation measures and monitor the recolonisation of animals post-construction.
Data is believed to be of high quality; all grid references have been verified for accuracy and data recorders have a wealth of experience in surveying for this species, therefore all records should be accurate.
Data is collected primarily in the form of field signs, which include feeding remains, latrines, runs, burrows and footprints. Incidental sightings of the species and sightings from mitigation trapping as part of animal translocations are also included in the dataset.
