beech tree leaves in winter

Wonderful article. The only thing strange about it was that the leaves were pure white. Beech and oak are believed to have originated in more southern climes and it’s been said that these species “have not yet perfected the deciduous habit.” OMG - A LEAF MAY BLOW OFF MID WINTER ONTO A LAWN. In years with early freezes tree leaves may be killed before developing an abscission layer, resulting in persistent brown leaves on many trees that aren’t usually marcescent. So far this winter trees are falling over everywhere on lines into road and near rivers and streams. “In autumn, the leaves of most deciduous trees develop an abscission layer where the petiole (leaf stalk) meets the branch. Can you offer an explanation as to why the flowering pear retains its leaves deep into December? The trunks are becoming porous and rotted, Peeling bark is exposing the core and killing the tree, There is splitting, and excessive growth of lichens, fungus and mosses (not just on the north side of trees)  I started to notice all of this in 2013 and the damage is massive. I would like to plant some to replace my dozens of Sandy victims and if I get them about six feet tall, could I hope for more than two or three years before they get too grown up for the look I admire? So it’s not just anal idiots who are the only ones that would like the leaves to drop conveniently all at once and don’t appreciate nature in it’s unbridled state. Thanks for answering a question I’ve been asking every winter as I admire the pinky beige leaves giving roadside woods color when otherwise pretty dull. Another example of nature deficit disorder. They are well-known to hold their leaves until new ones appear in spring. Might it perhaps be caused by our climate? I have one that I bought at a nursery in New Jersey—does not look like a white pine—bark definitely looks “corky”. It may be winter, but these beech trees at Knox State Park in East Aurora, New York still have leaves on them. As it seemed there are more beech trees with leaves this year than I have seen, I wanted to learn why. Here’s a summary of the phenomenon by an Extension expert in Minnesota: “Deciduous trees are supposed to drop their leaves in autumn, right? Today I noticed that a shingle oak (Quercus imbricaria, a marcescent species) was losing leaves over time with some falling today, but no new growth is yet visible. A Master Gardener suggested the trees felt stressed by the drought and produced more “babies” to ensure long-term survival. A related topic: acorns. I found many insight. I have not documented it, but I have noticed in years when ther red oaks retain their leaves well in to January and February, they have a good crop the following year. So your article had made some sense to this mystery. So why are there still lots of brown leaves clinging tenaciously to certain trees in our neighborhoods and natural areas? The process of shedding leaves is … I’ve lived here over 20 years and for a good part of that time have wondered about the young beeches keeping their leaves all winter. My hunch is that this particular maple is growing near a beautiful beech and is jealous! Very interesting article, often wondered about it myself. I walk my dog a lot and noticed a tree with leaves on it. I have always admired the Beech trees and how they hold their dried leaves all winter. Over the last few years it has been very noticeable that, although all the leaves turn brown in autumn (May/June here being in the southern hemisphere fewer and fewer are actually shed. To ensure a respectful dialogue, please refrain from posting content that is unlawful, harassing, discriminatory, libelous, obscene, or inflammatory. To understand this, consider both the physiology and the evolutionary history of trees. I have a tree in my garden which I have always taken to be a white oak. Some ecologists suggest that marcescence has adaptive significance for trees growing on dry, infertile sites. Most of the conifers are yellowing or dying!.. Does anyone know how many years one can expect to enjoy the marcescence until the tree outgrows it? –Nancy Rose, University of Minnesota. As a somewhat avid walker/hiker, I have always wondered why the leaves did cling to some trees longer. As the girdled tree decays,  the smaller trees around it grow and take up the space once occupied by the girdled tree. These clinging leaves made me pray harder for his soul. Thanks again for the info. I appreciated that you explained that we are still learning about these trees and do not have all the answers. My guess is that it’s the usual small genetic variability that explains this. I’ve always only been interested in heavy metal and softball, never thought I’d be looking up why the leaves won’t fall from only one of my trees. Excellent article, thanks! I have often wondered what causes this, as opposed to having one single trunk. I know this is not coming from parasites or insects but something else happening in our environment. Leaves started to die and shrivel up on the south side in the early summer. American hornbeam, also known as blue beech (Carpinus caroliniana), and ironwood, aka American hophornbeam (Ostrya virginiana) also tend to hold leaves. It was the end of March btw so those leaves have been there for quite some time and ive never seen leaves turn white. We have two properties, one in upstate New York: Maples, Beeches, Sumac, Cherry, etc., no oaks. Nearly Native Nursery is one of the only local nurseries to sell the American Beech. Dry leaves stay on marcescent trees because the leaves didn’t develop the normal abscission layer in autumn. Great article! Marcescence is the term used to describe the retention of dead leaves on deciduous trees through the winter. Some tree species are more likely to show marcescense than others. You answered my question about beech leaf retention. It is almost July. Beech leaves are a very potent hazard to waxed XC skis; they lurk in groomed tracks and fasten themselves to grip wax, often resulting in falls or at least bad language….   |   Visit the Articles archive…. Buds hidden by clusters of dead leaves do not get eaten and thus live to become new shoots and leaves in spring. A: I’ll bet you’re seeing American beech, Fagus grandifolia, trees. “Marcescence is often a juvenile trait and may disappear as the tree matures. ↑ top 16 On the Common Q: What is the small tree that has light brown leaves in winter? We have had snow, freezing rain and temperatures in the single digits. Thus our colorfully famous, broad-leafed hardwood was born. Right now all the other maples are bare. One possible advantage my son suggests is that the leaves on these trees seem to be more completely “stripped” down to a pale, low weight version of the leaves that come down in autumn—could the trees also be taking more from them? Tags: beech, leaves, oak, trees, vermont, wint. Could it be also that they remain closer to being evergreens? I have seen this many times in other trees. The leaves come on sooner in the spring and shed much later in the fall. I’m wondering what causes this. Now I know some the science behind it. They are held in place by just a small element of the abscissa. The question remains then as to whether there is any ecological advantage to being somewhere in between. In fact, the beech family includes many, get this, evergreen species (live oaks and tanoaks, for example, which do not grow in our region). I’m curious if the old leaves, though ‘dead’, could be directly supplying nutrients back to the budding branch, before falling off. ©2020 Walter Reeves / The Simple Gardener, Inc. All Rights Reserved. Still others have hypothesized that persistent leaves might provide some frost protection for buds and new twigs over winter. Sure enough, that’s often where we see beech and oak growing well and outcompeting other species. Their leaves die, but many don’t fall when they die. I can see several of them clearly in the woods near my house. Northern Woodlands assumes no responsibility or liability arising from forum postings and reserves the right to edit all postings. Michael Snyder is the Chittenden (Vermont) County Forester. Though they appear to be fully leafed at all times, evergreen leaves are not always green, and entire age classes of needles die, turn brown, and fall every year. The change in the old leaves overnight was remarkable. But it may also be simply a sign that beech and oak are evolutionarily delayed, still on their way to becoming fully deciduous from their more evergreen past. Each has its advantages and downsides, and over millennia, most species seem to have settled in to being one or the other. This year was phenomenal in number and size and quality. But there is great variation in the timing of this leaf fall. I have a theory that Oak trees retain their leaves to protect the acorns as they develop. one in Paterson, NJ: massive 80 year old oaks that were clearly part of the original 1939 landscape design and a lot of wild cherry and maple saplings the previous owner let grow up on the perimeter of this corner lot as a screen. From, the Friends of American Legion and Peoples State Forests, Inc. (FALPS). With new growth in spring the old brown leaves stay on the tree and appear to interfere with new growth. Populations of those earliest evergreen trees encountered changing growing conditions as they expanded their ranges and as the long march of time proceeded. I enjoy reading your articles, and enjoy all the facts and especially the pictures and “What in the woods is that.”  By far, my best reading. Thank you for the great article and comments. Upstate house all leaves down except the beeches. We do not know whether marcescence provides a competitive benefit to beech and oak, but we do know that these two species are closely related; they are in the same family (beech). A Beech tree in winter with russet brown leaves & cloudy sky , Stackallan, Slane, County Meath, Ireland Beech tree in winter, one leaf is left Beech tree in winter, one leaf is left Always raking leaves in the spring from around my house and yard, just seems peculiar raking leaves twice a year, now I understand more about the trees, thanks for the information. | Terms of Service | Privacy PolicySite by eBree Design. My theory based on the observation of our Paterson oaks is that the male oaks did their duty in Spring and can shut down and let go to sleep once they’ve produced enough sugar for bud break next Spring. We here at Northern Woodlands are unfamiliar with any particular method for stripping dead leaves from oaks, as none of us have ever tried to do that. Therefore the sumac produces brilliant red cones. This appears to hold true for the Paterson oaks. Apart from being unaesthetic these areas of dead leaves harbor pests such as aphids and scale insects which afflict the tree during summer. I love our flowering pear tree and its’ wonderful characteristics, except for the late December leaf dropping. It’s not a preferred food, but it is high in fat and a good winter food source for birds. I typed in Google search “oak tree still has leaves” and yours was the first answer. Thank you for the info. Kinda of gave me the creeps everything around it was dead. If so, what is the purpose & which kind holds on to the leaves? I have also read that regardless of the weather, oak trees will produce bumper crops of acorns every second year. Even small amounts at the right time could shift the competitive advantage toward these species on poor sites. There needs to be some explanation for this mass destruction which I am documenting meticulously! I find it astounding that no one has noticed how sick most of trees are in Vermont, Trees of all ages are not losing their leaves in the fall! While physiologists agree that marcescence is a juvenile trait, most commonly observed on young trees and on lower branches, there is considerable debate about why some species would seem to be deciduous in all other respects except that they delay the physiological process of leaf shedding. Some souls may cling around lower frequencies because of their attachments instead of letting go. Female oaks still in full dress, albeit brown dress. They seem to be the same type.
