The thematic network has been the primary mission of the ALPARC network since it was set up in 1995: to enable the personnel of the protected areas to exchange ideas on their practices, know-how and experience on common thematics, throughout the Alps , beyond linguistic and administrative borders.

It therefore aims at regular technical exchanges between the administrators of protected areas as well as other associated bodies, by conferences, symposiums and thematic training, workshops and study trips or, again, through publications, collections of good practices and other communication supports (Internet/Extranet).

The thematic network rests notably on the working groups, the number of which changes according to needs. These groups work on concrete projects such as the reintroduction or monitoring of species of fauna, welcome policy and tourist flow management, common communication and the management of protected areas or, again, on measures against climate warming (human-powered mobility,, ecological constructions…) and can give rise to international projects (LIFE Bearded Vulture, Interreg Habitalp and Alpencom…) or to common productions (travelling exhibitions, common communication tools…).
