The association works with issues related to environment, sustainability, and nature's rights, and carries out various types of activities such as excursions, inventories, discussion forums, actions and meetings.

The organization operates all over Sweden, the largest district being Fältbiologerna Stockholm-Uppland-Gotland.

One of the traditional annual highlights is the National Annual Meeting (Swedish: Riksårsmöte) arranged during the first week of January, and the Öland-camp which is held in Grönhögen in southern Öland during one of the long weekends in May.

The members start a club for children aged 6–12 and organize activities for them.

Nature and Youth Sweden's magazine, Fältbiologen, focuses on topics regarding nature, research, and environmental issues,[2] and has published several important texts on topics such as forestry preservation.
