Water Vole FAQs

Water vole survey data is generally considered valid for 1-2 years, depending on the scale and nature of your development. If your planning application is delayed or your project timelines change, you may need to update the surveys to ensure the data remains current. 

If water voles are confirmed present, you will likely need to apply for a conservation licence before you can proceed with your development. Lucion can manage this process on your behalf, designing and implementing tailored mitigation strategies to avoid, minimise or compensate for any impacts on this protected species. 

The standard water vole survey process includes a habitat assessment to determine the suitability of any watercourses, followed by presence/absence surveys using techniques such as fingertip searches, float surveys, and burrow inspections. These surveys allow us to confirm whether water voles are present and estimate the population size. 

Water vole surveys can only be undertaken between April and September, with the optimal period being from mid-April to June during the peak breeding season. Surveys must not be carried out immediately after heavy rainfall, as field signs may have been washed away. 

Water voles and their burrows are fully protected under the Wildlife and Countryside Act 1981. If your development has the potential to impact water voles or their habitats, you are legally required to undertake surveys and obtain the necessary licences before proceeding.
