NatuurNetwerk’s Fauna Registratie Systeem (FRS) is an online service for recording and managing information related to fauna management in the Netherlands. The system supports the registration of measures used to keep certain animal populations at a desirable level. According to the site, these measures may address damage, balance populations with the capacity of their habitats, or respond to exceptional circumstances such as disease or severe weather. They are prescribed by provincial authorities and require explicit written permission.

The FRS provides account-based access, with login options for registered users and tools to recover a forgotten password or manage a phone linked to their account. Users who previously signed in by scanning a QR code through the Notifier app can unlink their current phone before connecting another device. The site also offers Android and iOS notification guides, information about WBE areas, and a privacy statement. For reporting damage or applying for authorization, users are directed to faunaschade.nl.
