Bat Survey Edinburgh: Protected Species Surveys

A Bat Survey, Edinburgh, is one of the many protected species surveys which may be an ecological requirement when applying for planning consent for a new project. As bats are a protected species, survey work to identify the presence of bats can inform a mitigation plan when undergoing development works to avoid the risk of unnecessary disturbance or harm to bats.

It is important to note that many local planning authorities may be legally obliged to delay or prevent a planning application if bats are found to be present and protection measures have not taken place. The Conservation of Habitats and Species Regulations 2017 were established to protect wildlife in the UK, particularly species vulnerable to development.

Such regulation means it is a criminal offence to capture, injure or kill a bat. Therefore, the proposed works should not damage or destroy a bat roost, nor should they deliberately prevent bats from roosting in any circumstance. With the aim of preventing further damage to bat populations in the UK, carrying out bat surveys and assessments can ensure that a project development supports a safe and welcoming space for bat species whilst obtaining planning permission.

When undertaking a bat survey, Edinburgh, our consultants could come across any of the species of bats currently active in the UK. Edinburgh happens to host a diverse range of bats, including:

• Common Pipistrelle
• Soprano Pipistrelle
• Nathusius’ Pipistrelle
• Brown long-eared bat
• Noctule bat
• whiskered bat
• Brandt’s bat
• Leisler’s bat

It is recommended that bat surveys are carried out during May and September, as this season witnesses a peak in bat activity. Should evidence of bats be recorded during the summer months, wintertime surveys are sometimes required to assess the possibility of bats using the site to hibernate.

The main types of bat activity surveys in Edinburgh include:

Preliminary Roost Assessment (PRA): The first type of survey is the Preliminary Roost Assessment (PRA), also known as a bat scoping survey. This involves a desk study, reviewing local bat records and databases. This is  combined with a site visit to inspect buildings, trees, or other structures for signs of bats. Evidence may include droppings, feeding remains, and potential access points. The purpose of this survey is to determine whether further, more detailed assessments are necessary.

Bat Emergence and Dawn Re-entry surveys:  If evidence suggests that bats may be present, an Emergence and Re-entry Survey is carried out. These surveys are conducted at dusk and dawn, using static bat detectors to record echolocation calls. They confirm the presence of bats, identify species, and locate roosting sites.

Nocturnal bat surveys: A nocturnal bat survey is a type of ecological survey conducted at night to observe and record the behaviour patterns of bat species. As bat activity increases during this time, nighttime surveys efficiently monitor local bat populations, identify species, and assess their habitats. A nocturnal bat survey is highly beneficial to the conservation of habitats, ecological assessments, and the determination of the nature of the impact on the surrounding environment of development projects.

Hibernation surveys: During the winter months, hibernation surveys are conducted to locate bats in hibernation sites such as caves, mines, tunnels, and tree cavities. Surveyors inspect these locations during the winter months, taking extra precautions not to disturb bat hibernation.
