Deciduous trees shed their leaves as an active process that evolved to conserve resources and protect the tree from being blown over in the windier winter months. Some birch trees turn yellow due to temperature changes in the summer early autumn. There is nothing to worry about. The trees will re grow the foliage again in the spring time.
