Dormouse Survey Techniques
The hazel dormouse inhabits deciduous woodland, hedgerows and scrub vegetation, often with a high proportion of Hazel. Their distribution in the UK is largely limited to the south of England and Wales. If you plan to develop a site containing suitable habitat and with historic records of dormice nearby, you will likely require a dormouse survey.
Over the past 100 years, this species has declined dramatically in numbers and distribution, at one point being declared extinct in up to 8 counties. Its decline is thought to be the result of a combination of habitat loss and changes in woodland and hedgerow management.
There are a number of techniques commonly used for surveying this species, some being more effective than others. At JCA a combination of two survey techniques are used to determine presence/absence of this species.
The majority of ecological surveys are seasonally constrained. Use our ecology survey calendar to plan your project timetable and factor in any seasonal constraints to project timescales as early as possible to prevent any delays.
