In the summer a trees leaves are green... they don't turn colors until autumn
Most deciduous trees lose their leaves in Autumn . . . trees like maples, linden trees, elm trees; however, oddly enough, many oak trees do not lose their leaves in Autumn. The leaves turn colors, and then die and turn brown. The dead leaves take their time to drop off. In my area, some oaks still have their dead leaves as late as early Spring.
So we won't have to cut down trees for the leaves, and leaves give us oxygen, and we NEED oxygen!!
Pine trees leaves do not change colour during autumn, as they are evergreen trees.
Maple trees are known for their vibrant red leaves in autumn. Other types of trees that can also turn red in autumn include oak trees, dogwood trees, and sweet gum trees.

Yes, elm trees are deciduous, which means they lose their leaves in the fall. The leaves turn yellow or brown before falling off the tree.
