In order to measure and better understand the impact of environmental factors on the Little Owl, scientific monitoring is carried out as part of a ringing program approved by the National Museum of Natural History; this allows, in particular, the main reproductive parameters of the species to be studied over the long term from pairs monitored in nest boxes.

The installation of nest boxes helps to compensate for the loss of habitat and the disappearance of nesting cavities available to this species due to constant urbanization in Provence, most often carried out to the detriment of agricultural land, the restoration of old buildings (mainly agricultural sheds) or the disappearance of old trees.

Each year, the Regional Wildlife Rescue Center rescues between 10 and 20 Little Owls. Once they are taken to a veterinary clinic, it is deemed too late and unsafe to attempt to return these young birds to their discovery site. They are therefore raised in captivity until they reach their full physical capacity during a stay in a rehabilitation aviary.
