Bat Surveys

Quants is proud of its excellent track record of providing first class bat licensing and mitigation, to clients and bats alike. We have extensive expertise in this area, having a number of Natural England bat licence holders within the company, offering a range of expertise across most UK bat species.

Depending on the type of project and time of year, different types of survey can be undertaken. We have the skills, capacity and experience to offer the following services:

  • Bat roost potential surveys
  • Presence/absence or dusk emergence/dawn re-entry surveys
  • Transect surveys
  • Static monitoring
  • Tree climbing bat surveys
  • Arrangement of dropping DNA analysis

Bats are fascinating animals, the only true flying mammal. There are over 1,300 species of bats in the world, and more are still being discovered. Bats account for more than a quarter of mammal species in the UK and around 20% of all mammal species worldwide. Bats play an essential part in the natural world and are indicators of a healthy environment. Their future is directly linked to our quality of life and the quality of our environment. However, approximately 25% of the world’s bats are threatened with extinction. In the UK, bats face threats ranging from predation to crime and loss of habitat. UK bats and their roosts are protected by law.

While some people think that bats are pests, some bats are actually pest controllers eating thousands of insects every night. All bats in the UK are insectivores and are great for keeping insects away from crops, as well as the places where the bats roost. Because bats eat so many insects in some regions, they can also reduce the need for pesticide sprays.

While bats can provide a valuable service for agriculture, some agricultural practices can have a detrimental impact on bats. Increased use of pesticides may mean that bats go hungry from the lack of insect prey. The destruction of hedgerows and woods in farmland is also concerning, as bats rely on these features for roosting, hunting and getting around.

Bats hibernate, and this can, on occasion, result in extreme seasonal difficulties when planning timescales for projects. However, with the right timely advice from our experienced ecologists, costly delays on projects can usually be avoided.

Mitigation for new developments can go some way to replacing some habitat and roost losses but needs to be specific to the species, the roost type and the supporting habitat.
