The park's surveillance service, keeping in line with tradition and without neglecting its strong points, is continuously evolving, with constant updating which goes from legal standards to mountain rescue, from notions of self-help to study of the fauna.
A service which today, along with the traditional surveillance activities, carries out other functions, such as regular police investigations, dealing directly with the public and participation in scientific research.
So it's the rangers themselves that collaborate with the Attorney's Office and with the municipal-engineering service of the park authority, give advice to tourists going on excursions, go to schools to talk about the park and contribute to various types of research conducted both by the park's scientific service and by universities.
