"Waarneming.nl is the largest nature observation platform in the Netherlands, with over 70,000 users contributing data on biodiversity through their website and mobile applications. Using Waarneming.nl as an example, the theoretical exploration in this article offers a new lens to look at platforms for nature observations. Users of Waarneming.nl read and write digital traces of encounters with other species, creating a ‘hybrid experience’ of nature, where digital and physical information are intertwined. As physical experiences become scarcer in threatening times of species endangerment and extinction, Waarneming.nl should additionally be understood as a place to memorialize lost nature. By conceptualizing Waarneming.nl as a digital 'lieu de mémoire' (‘place of memories’) and a place where hybrid experiences of nature are inspired, this article reflects on the positive and negative consequences of such platforms for humans and their multispecies relationships."
