Protected Species Survey
Water Vole
Water voles (Arvicola amphibius) are a protected species under the Wildlife and Countryside Act 1981 (as amended), making it an offence to intentionally kill, injure, or disturb them, or damage, destroy, or obstruct their habitat. As a key indicator species of healthy riparian ecosystems, their presence is a crucial consideration in ecological assessments for development and land management projects.
When is a Water Vole Survey Required?
A water vole survey may be required if a proposed development or land management activity is near a suitable watercourse, including rivers, streams, ditches, ponds, and wetland habitats. Local planning authorities and statutory bodies often request surveys as part of planning applications to ensure compliance with wildlife legislation.
Water Vole Survey Methods
At Wildfox Ecological Consulting, we conduct detailed water vole surveys in line with best practice guidelines from the Mammal Society and CIEEM. Our surveys typically involve:
Habitat Suitability Assessment – An initial assessment to determine the potential for water voles to be present.
Presence/Absence Survey – A systematic search for field signs, including burrows, latrines, feeding stations, footprints, and droppings.
Population Assessment – Where required, we conduct repeat surveys to estimate population density and activity levels.
Timing of Surveys
Water vole surveys are best conducted between April and October, when the animals are most active and field signs are easiest to detect. Surveys outside this period may be inconclusive due to reduced activity and vegetation cover.
Mitigation and Licensing
If water voles are found on-site, appropriate mitigation measures must be implemented. This may include habitat enhancement, translocation under licence, or modifying development plans to avoid disturbance. Our team can guide you through the Natural England licensing process where required.
