Tree species in Norway (Treslag i Norge) is an application that allows you to identify the most common tree species in Norway. The target group is pupils and the explanations are therefore based on images, and not so much on words. The app is meant as an aid throughout the whole year. The species are presented with a complete set of pictures from all four seasons: buds, leaves, flowers, fruit, bark and branches, in addition to the whole tree.

You may also identify your tree by using identification keys. Two different keys have been developed, one for the leaves in summer and one for the buds in winter. Not everyone is familiar with the biological terms of leaf and bud identification, therefore each choice is illustrated.

This tree identification app was developed by the Forestry Extension Institute in Norway. It is available for free on mobile phones and tablets for both Android and iOS operating systems.

The language of the application is Norwegian but can still be used by others, due to the many images and illustrations. As an aid, a short instruction manual in English has been made. You can download it by clicking here.
