* Conservation of water: In winter, the ground freezes, making it difficult for trees to absorb water. By shedding their leaves, trees reduce the surface area through which they lose water through transpiration.
* Protection from damage: Frozen water expands, and if water remains in the leaves during freezing temperatures, it can damage the delicate cells. Shedding leaves prevents this damage.
* Preparation for spring: By shedding leaves, trees can conserve energy and resources that they can use for growth and reproduction when the weather warms up in the spring.
Think of it this way: Shedding leaves is like a tree going into hibernation, preparing for the harsh winter months and conserving resources until they can flourish again.
While deciduous trees (trees that lose their leaves) shed leaves in autumn, evergreen trees (like pine and fir) keep their leaves all year round. Evergreen trees have adaptations to survive the cold, such as needles that are coated with a waxy substance to prevent water loss.
