naturbasen.dk

Naturbasen is a Danish online community and app for logging observations of plants, animals and fungi. Members share sightings and help each other identify species through a species identification section, comments and a forum archive. The site also includes a species encyclopedia covering about 40,000 Danish species and atlas projects for groups such as butterflies, dragonflies, amphibians and reptiles.

Membership is free, and observations can be submitted on the website or through the Naturbasen app for iPhone and Android. The submitted data is quality-checked and, under cooperation agreements, used by municipalities and national parks for nature management. The stated collaborators include ministries, national parks, municipalities and consultants.

The portal describes itself as having 120,360 members and 25 years of experience in public nature monitoring (citizen science). Its stated purposes include collecting observations of Danish flora and fauna, supporting nature management and research in Denmark, and building a network of nature enthusiasts.
