A close-up image shows the white bark of a birch tree with dark patches and horizontal lenticels. Birch trees are known for their white bark, which peels in horizontal strips. The dark patches on the bark are likely caused by lichens or other organisms growing on the tree. Lenticels are small pores in the bark that allow the tree to breathe.
Based on the image, it is difficult to say definitively which species of birch tree this is. However, some common birch trees in Sweden include the silver birch (Betula pendula), the downy birch (Betula pubescens), and the paper birch (Betula papyrifera). These three species all have white bark that peels in horizontal strips.
