EcoVigour undertake dormouse surveys in line with the most recent (2025) guidance which allows survey effort to be proportional to the works required and risks to dormice. We will tailor our approach to your project using the many years of experience of our team to deliver the optimum approach with minimal disruption to project programme.

Surveys from nut searches / habitat assessments to nest tubes / footprint tunnel surveys, delivered by dormouse licensed ecologists.

Hazel dormice are a fully protected species in the UK, and their presence can significantly influence development proposals. EcoVigour provides comprehensive dormouse surveys to support planning applications, licensing, and habitat management.

Why are dormouse surveys required?
Dormouse surveys are typically required where suitable woodland, hedgerows, or scrub habitats are present within or adjacent to a site. Surveys help to:

• Ensure compliance with the Wildlife and Countryside Act 1981 and Habitats Regulations
• Provide robust evidence to support planning applications
• Identify potential impacts on dormouse populations and habitats
• Inform appropriate mitigation, compensation, and licensing strategies

Survey methods
Our surveys are designed in line with recognised guidance, including the Dormouse Conservation Handbook and Natural England licensing requirements. A combination of methods may be used depending on habitat suitability and project scope:

• Habitat Assessment
  An initial assessment to evaluate the suitability of vegetation for dormice, including species diversity, structure, connectivity, and food availability. This helps determine the need for further survey effort.
• Nut Searches
  Systematic searches for characteristic gnawed hazelnut shells, which can indicate dormouse presence. This method is particularly useful in autumn when nuts are abundant.
• Nest Tube Surveys
  Installation of artificial nest tubes within suitable habitat, which are checked regularly (typically monthly) for evidence of dormice such as nests or individuals.
• Footprint Tube Surveys
  Use of inked tracking plates within tubes to record footprints, allowing detection of dormice without direct handling. This can be a useful complementary or alternative method in certain situations.

Survey methodology and seasonal constraints
Dormouse surveys are highly seasonal and must follow established survey windows:

• Nest tube and footprint tube surveys are typically undertaken between April and November, with multiple checks required to achieve sufficient survey effort.
• Nut searches are most effective between September and November.
• Habitat assessments can be undertaken year-round, although spring to autumn provides the most reliable results.

Survey design, including the number of visits and duration, is guided by best practice to ensure results are robust and suitable for planning and licensing purposes.

Our approach

• Surveys undertaken by licensed and experienced ecologists
• Methodologies aligned with current best practice and regulatory guidance
• Clear reporting to support planning submissions and licence applications
• Practical mitigation strategies tailored to your site and programme
