Performing badger surveys are necessary because badgers and their setts are protected under the Protection of Badgers Act 1992. This legislation is welfare-based rather than conservation-based, to prevent intentionally cruelty, such as baiting. The Act allows for working with badgers, often under licence, when they are affected by development or are causing damage to things, such as utilities, property or archaeological features.

It is an offence to either intentionally or recklessly interfere with, damage, or block a badger’s sett while it’s in use.


When planning a development, developers need to consider the potential presence of badgers in, or in the vicinity of, the works area.  All our badger surveys are carried out by experienced and qualified ecologists who are registered with the Chartered Institute of Ecology and Environmental Management (CIEEM).

If badgers are present

If badger setts are likely to be impacted by the works, and these impacts are unavoidable, setts may need to be closed under licence. A licence will be required from the applicable Statutory Nature Conservation Organisation (SNCO) e.g. Natural England.

Once received, badgers can be excluded by fitting one-way gates to setts. Exclusion can be conducted from the start of July until the end of November.


Mitigation calendar

Badgers mitigation calendar

Mitigation and compensation for impacts on badgers can include:

  • Tunnels beneath roads within the development,
  • Burial of badger-proof barriers,
  • The creation of artificial setts.

When it comes to the creation of artificial setts, ADAS ecologists can provide detailed advice for any construction activities.

If you would like to discuss any aspects of badger ecology or mitigation, do not hesitate to contact Associate Director James Simpson.
