Transect Surveys, Preliminary Roost Assessment, Bats, common pip, Bat Activity, Hibernation Survey


All bats and their roosts are protected under:

  • The Wildlife Act 1976 and subsequent amendments (2000)

When do I need to get in touch?

Bats roost in a variety of structures throughout the Ireland. If work is planned on buildings (including modern builds), bridges, trees or other structures it is important to contact us as bats could be present. Planners may also advise that bat surveys should be undertaken to structures undergoing planning consent.

To prevent delays in your project it’s important to get in touch as early as possible as bat surveys are highly seasonal and any mitigation required can take some time to process.

How can EcoÉireann help me?

We advise you on bat protection and your options. We undertake all types of bat surveys, licencing and mitigation. We apply best practice guidelines along with our in depth knowledge of each particular species, habitat requirements and present the results in our detailed professional reports to inform and support your projects planning application or other consenting process.

Bat survey types and when they can be undertaken are detailed below:

Preliminary Bat Roost Assessment (structures & trees) Initial survey, to determine bat potential and roosting signs on trees or buildings Year Round
Activity Surveys Dawn and dusk surveys to determine bat activity to inform on species and population counts May – September
Transect Surveys Surveys throughout bat foraging areas to determine areas important to bats May – October
Hibernation Roost Inspection Survey for hibernating bats November – March
