T ree species in Norway (Treslag i Norge) is an application 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.
