In terms of tree classification, what do hardwoods typically lose in the fall?

Hardwoods are classified as deciduous trees, which means they go through a process of shedding their leaves in the fall. This seasonal leaf drop is a strategy to conserve water and survive the colder months when water is less available and photosynthesis cannot occur as efficiently due to decreased sunlight. By losing their leaves, hardwoods reduce the amount of moisture lost through transpiration and prepare for dormancy during winter.

In contrast to hardwoods, evergreens, such as pines and firs, retain their leaves (needles) throughout the year, which is why they do not lose needles in the fall. The other mentioned options—bark and roots—are also generally not lost in the fall. The shedding of bark is a normal process that occurs over longer periods for maturation or healing, and roots typically remain intact year-round to support the tree's overall health and growth, even during winter dormancy.
