We advise that you arrange for a bat survey to be carried out as soon as possible if a development process is likely to negatively impact on bats or their roosts, commuting or foraging habits. In particular if the proposed development site includes buildings or built structures, underground structures or trees that provide roosting.
Planning ahead and arranging a bat survey will save you having to consider the costs of mitigation later on in a project, at a point where it may be too late, and you may find you are engaging in illegal activity. This will also ensure you can implement any necessary actions before the bat survey season begins.
