In 2023, a project was launched to construct an infrastructure to identify every living species in the Netherlands and to monitor biodiversity. The digital platform, called ARISE (Authoritative and Rapid Identification System for Essential biodiversity information), is the first of its kind in the world.

The platform is already accessible for researchers.
