In order to measure and better understand the impact of environmental factors on the Little Owl, scientific monitoring is carried out within the framework of a banding program approved by the Muséum national d'Histoire naturelle; in particular, this enables long-term study of the species' main reproductive parameters, based on pairs monitored in nesting boxes.
The installation of nesting boxes helps to offset the loss of habitat and the disappearance of nesting cavities available to this species as a result of constant urbanization in Provence, often at the expense of farmland, the restoration of old buildings (mainly farm sheds) and the disappearance of old trees.
