Abstract: Disclosed is a method for monitoring an installation having a first level of dangerousness for an animal species in a first operating state (E1), the method including a step (107) in which the installation is switched to a second operating state (E2) in which the installation has a second lower level of dangerousness. The installation is switched to the second operating state on the basis of at least one criterion linked to the activity of the animal species or on the basis of a multivariate model for predicting the activity. Also disclosed is a computer program including instructions for implementing the method, to a device for implementing same, and to a system including such a device.
