Deciduous trees generally lose their 'dead leaves' yearly, thru a process called leaf abscission. Ofcourse there are always exception and there are some species of plants that dont abscess their leaves, like many in the plant family Fagaceae which contains the genera of oaks, chestnuts and beech. While its not exactly clear why it happens, I do have some interesting tidbits...
Its been asked alot in botany depts why this happens to this family specifically. Recently, there has been lots of work done showing the actual genes and cellular mechanisms of abscission. And simply put, it seems that Fagaceae doesnt turn those genes on very well but the leaf is definitely unhooked from the rest of the plant... in essence dead weight, just not fallen off.
I could imagine some evolutionary benefits of leaves falling in the spring as opposed to fall. Specifically not letting leaf disease overwinter in the warm soil but the harsh windblown branch. Also spring time leaf mulching.
Dr Evert of UWMadison who is a well known plant anatomist prof did some of the initial work to confirm that infact the leaf of the non abscessed Fagaceae was dead weight to the plant. I believe even to this day, he doesn't have a solid reason on the 'why' but you can research his work if you want the original research papers.
The leaves of a mature beech tree will fall during the Autumn and early Winter. The leaves of a well maintained beech hedge will stay on all Winter. This is either due to the close grouping of the cut hedge or the fact that young, protected shoots can hold on to their dead leaves.
Beech trees have a unique ability to retain their leaves in the winter due to a high level of tannins and other compounds in their leaves that help protect against freezing temperatures. This retention of leaves in the winter is known as marcescence and is thought to provide additional protection to the tree against herbivores and harsh weather conditions.

Is beech tree a deciduous tree?
Yes, the Oak tree is deciduous. However there are afew species of Oak that hang onto many of their leaves through all the seasons. These are considered evergreen Oaks because they can stay green all year long. One such Oak is the Live oak from the southern part of the United States.
What does deciduous and ever green mean?
Deciduous trees lose their leaves in the fall and remain bare during winter, while evergreen trees retain their foliage year-round. Deciduous trees typically shed their leaves as a way to conserve water and energy during colder months, while evergreen trees have needle-like leaves or leaves with a waxy coating that help them retain water and stay green throughout the year.
What are some examples of deciduous trees?
Maple, oak, birch, beech, and aspen are examples of deciduous trees. These types of trees shed their leaves annually in response to changes in temperature and daylight. Deciduous trees are commonly found in temperate regions around the world.
What happens to the leaves of a Deciduous trees?
Deciduous trees shed their leaves in the fall in response to changes in temperature and daylight. This process, known as leaf abscission, helps the tree conserve water and energy during the cold winter months.
What are trees that lose their leaves at the end of the season called?
Deciduous trees are trees that lose their leaves at the end of the growing season. This process is known as leaf abscission. Examples of deciduous trees include maple, oak, and birch.
What is the type of tree that keeps its leaves in the winter?
Evergreen trees retain their leaves through the winter.
What does evergreen mean in referring to trees?
they don't have leaves, and don't lose their foliage in winter, they stay green.
What are ever greens?
"Ever greens" are trees that do no shed their leaves in winter and therefore stay ever green.
Why do Mango and banyan trees shed their leaves in winter?
because at this time their leaves are not required and the wood is used mainly.
What is a tree that does not stay green all year?
Deciduous trees (broad leaf trees) such as English Oak, Beech and Elm.

Why are needleleaf trees also known as evergreen trees?
Needleleaf trees are also known as evergreen trees because they retain their needle-shaped leaves throughout the year, even during winter. This helps them stay green and photosynthetically active all year round, as opposed to deciduous trees that shed their leaves in the fall.
What is the name of trees that shed their leaves in winter?
threes that lose their leaves in the winter are called deciduous trees. They lose their leaves to conserve moisture and reduce the amount of energy they must consume in order to stay alive. The leaves of some deciduous trees turn bright colors before they drop to the ground, while others simply fade or turn brown. Environmental factors and the genome of the tree affect how quickly the leaves fall.
Deciduos trees stay green all year?
You have it backwards. Deciduous trees are the ones that lose their leaves in the winter. They're the ones with the colorful leaves in Fall. Conifers are the ones that stay green all year long. They can do that because they have thin needles instead of leaves, and needles don't freeze as easily as leaves do.
