All trees lose their leaves at some point in their life cycle. It's just that some do it more dramatically than others.

* Deciduous trees are the ones we most associate with losing leaves. They lose their leaves in the fall and grow new ones in the spring. Examples include oak, maple, birch, and elm trees.

* Evergreen trees also lose leaves, but they do it gradually throughout the year, so it's less noticeable. Examples include pine, fir, and spruce trees.

So, while it might seem like some trees "don't" lose their leaves, they all do, just at different times and in different ways!
