What are evergreen trees? As is apparent from the name, the evergreen trees have green foliage all around the year. So, unlike the deciduous trees, which go bare in colder temperatures, these can add color and vibrancy to your garden, even during the dead of winter.

 

Many even present glorious colors on display during the fall. So, even if the older leaves fall, the new ones keep growing. Most evergreens are forgiving. They can thrive even in soil, lacking nutrients as they process whatever food they receive around the year.

 

People associate Christmas trees and Pines with evergreen trees. However, it is a general term for all shrubs and trees that maintain foliage across the year. The lifespan of evergreen trees is significantly good.

Benefits of Evergreen Trees

There are a plethora of benefits associated with evergreen trees. Beyond their visual appeal, the evergreen trees work as winter shelters for wildlife, especially birds, privacy screens, and windbreaks. If they have low branches, they can also give ample shade underneath.

 

Some evergreens bear edible fruits and berries, while others have beautifully-shaped cones and bear flowers, seeds, and nuts. People also resonate with evergreen conifers having an aromatic and delicious fragrance wafting across the garden.

 

Their textured and colored barks are also a distinctive feature. The only plausible low to the evergreen trees is their size. They grow tall and tower properties. So, if you have a small yard, it can be overwhelming in your residential space.

 

But, there are some dwarf varieties as well. You can also prune them to maintain their visual appeal. Given the growing conditions in your region, you have endless evergreen tree choices to pick from.

 

The Average Life Expectancy Of Evergreen Trees

Shrubs and trees like spruce and pines yield seeds in cones instead of flowers or berries. These evergreens have leaves all around the year. Typically, they have a long life. However, the actual lifespan of evergreen trees depends on the soil where they grow, geographical and environmental conditions, and the care they receive.

 

Generally, they are hardy and can tolerate even the colder conditions. Presently, over five hundred species of evergreen plants are on the planet. Now, the question is, how long do evergreen trees live?

 

Horticulture experts suggest that evergreen plants are the longest-lived woody plants that stay for around 100s of years. They are even older than flowering plants by at least millions of years.

 

Below, we will discuss how long do evergreens live – the common ones.

 

A. Pines

Pines are amongst the oldest found trees. There are multiple species of Pines, and each of them has a different lifespan. But, the average lifespan of evergreens ranges from 50 to 450 years. Here, we will discuss the average life of prevalent pine trees.

 

1. Ponderosa pine– If you ask how long do evergreen trees live? Commonly seen across western America, these trees have a lifespan of 300-500 years. There is an oldest documented tree in Utah that is about 800-years old.
 
2. Eastern white pine– The lifespan of evergreen trees is between 100-200 years. Scotch pine – These trees can live between 150-300 years.
 
3. Bristlecone pine or Methuselah– is the oldest tree in America. You can spot them in California’s White Mountains, and they are over 4700 years old.
 
4. Mugo pine tree Their average lifespan is half a century.
 
5. Norfolk island pine tree – Norfolk Island Pines usually live for over 15 decades.
 
6. Lodgepole pine– These can easily live four centuries.
 
7. Italian pine tree– These conifers live between 50-100 years.
 
8. Golden Pine Trees– The life expectancy of Golden Pine Trees is between 60 to 90 years.
 
9. White Pine– White Pine has an average lifespan of two centuries, but they usually live to 450 years.

 

Neither a true fir, pine, nor spruce, Douglas Firs, tends to outlive most evergreen coniferous trees. They have an average life expectancy of 75 centuries.

 

B. Spruce

How long do evergreen trees live? Spruce is native to Canada and the western United States. The spruce trees have an average life expectancy of 250 to 300 years. However, you can also find older spruces up to 1000 years. Here, we will discuss the average life of prevalent spruce trees.

 

  • White spruce live for two centuries or more. Many documented white spruce is over three hundred years old, and you can spot them in Manitoba, Canada.
  • Silver Spruce or Colorado Sprucehas been around since 1862. They live for about eight centuries.
  • Blue Spruce’saverage lifespan is 150 years, but many reach 350 years.
  • Norway Spruce, native to Canada and the central United States has a short life. They rarely pass 220 years.

 

C. Junipers

These are evergreen plants that yield berries that are cones and not fruits. The color of berries goes from blue-purple to blue, copper, or red. Broadly, there are three kinds of junipers. They have a peculiar smell.

 

This distinctive aroma makes it easy to spot Junipers from a distance. The lifespan of evergreen trees is not very long. Most junipers live only 150 years.

 

D. Redwoods

These are amongst the world’s tallest trees, typically about 350-400 feet. Redwoods are rapidly-growing conifers and grow about three to five feet per year. In a quarter-century, they get about 90-feet tall. They have a long life and usually live for six centuries. Only two kinds of redwood are still prevalent in North America – the giant sequoia and coast redwood.

 

Where are Evergreen Trees Found?

Typically, Evergreen Trees can be present anywhere in the world except Antarctica.

 

You can spot Broadleaf, Coniferous, temperate, mixed, and evergreen trees in temperate mid-latitudes. Predominantly, they are a common sight in:

  • Orinoco and Amazon basins of South America
  • Scandinavia
  • Siberia
  • Indonesia
  • Himalayas and western ghats of India
  • Malaysia
  • Australia
  • Canada
  • Andaman and the Nicobar Islands
  • Africa

 

Are Evergreen Trees Endangered?

Some evergreen tree species are at the risk of vanishing from the earth, but since there are over 630 varieties of evergreen trees, it is almost impossible for them to go extinct.

 

However, a beautiful evergreen conifer, Florida Torreya, has experienced a ninety-eight percent decline in its population since the 1950s. At present, less than six hundred individual trees are remaining.

 

Another variety is the Boynton Oak. It is a semi-evergreen tree and is critically endangered. At present, only 50 to 200 varieties remain in the wild.

Lifespan Of Evergreen Trees – Frequently Asked Questions

 

Ques 1. How long do evergreen trees live? Do evergreens live forever?

Ans. Evergreen trees have a long lifespan of 100s of years, but they do not live forever.

 

Ques 2. How do you tell if an evergreen tree is dying?

Ans. Evergreen trees die slowly, and their parts may show some signs of life, even when it is impossible to bring back the plant to life.

 

As plant sheds needles in later life stages, the yellowing needle is a part of the plant’s routine life cycle. The conifers’ evergreen foliage lasts from two to ten years, depending on the variety. But, how to know if your plant is dying? Watch out for symptoms discussed below:

 

  • Check the canopy. Even when your evergreen trees may be shedding old needles, they will still have ample green foliage. So, if the branches have just brown needles, there may be a problem. 

    If the brown branches are somewhere between many healthy green branches, it could indicate stress in the plant. It means the plant is alive, and you can undo the damage. Usually, the brown needles appear because of overwatering, soggy soil, some disease, or underwatering.

     

  • You can also tell a tree is dying from its leaves and needles. So, analyze them by bending them together in between your fingers. If the plant is healthy and living, the foliage is strong. Hence, it would not break easily.
    However, if the leaves and needles are dry or dead, they will snap when flexed. On the exterior, they may appear green, but they have barely any life left inside.

     

  • Another way to identify a dying evergreen is by checking the bark. If canopy assessment spells damage, you can next make a small slit in the bark with a knife. Then, snoop aside or chip away the dead dry exterior. 

    Check the green cambium layer over the moist sapwood. If the green layer is absent and the bark is brown throughout, it can indicate a severe injury. Unfortunately, it is impossible to reverse this damage.

     

Ques 3. How long do evergreen trees live to adult?

Ans. When evergreens mature, they are considered an adult. Most evergreens take seven to ten years to adult, while some attain maturity even faster.

 

Ques 4. What tree has the shortest lifespan?

Ans. The tree which has the shortest lifespan is Peach. On an average its life expectancy is 10-15 years.

 

Ques 5. What is the life of a conifer tree?

Ans. The lifespan of conifers ranges from a few decades to over 5000 years.

 

Ques 6. Will evergreen needles grow back?

Ans. While the plant discards its old needles, it does not take too long to grow new ones.

 

Ques 7. What is the lifespan of a pine tree?

Ans.  The lifespan of evergreen trees (Pine)is very long that lies somewhere between 100-1000 years.

 

Ques 8. What is the difference between deciduous and evergreen trees?

Ans. The primary difference between a deciduous and an evergreen tree is that the former loses its leaves during the winters, but evergreen trees remain green across the year.

 

How Long Do Trees Live? - Evergreen Arborist Consultants

About 270 miles north of Los Angeles, a remarkable tree juts out of a rocky landscape. The tree isn’t terribly attractive, nor large, nor some member of a critically endangered species.

This tree is remarkable because it is about 5,000 years old – give or take a few decades.

The tree in question is a bristlecone pine (Pinus longaeva). A hardy species that thrives amid harsh landscapes, there are many ancient specimens growing throughout the eastern portions of our state and parts of Utah and Nevada.

For some time, researchers believed they had identified the oldest living individual – 4849-year-old specimen named Methuselah. However, researchers recently documented an unnamed individual which appears to be about 150 years older than the previous record holder.

We know that this tree grows in the Ancient Bristlecone Forest (part of the Inyo National Forest), but to protect the trees from vandals, its precise location has not been divulged to the public.

Which Tree Species Live the Longest?

Bristlecone pines aren’t the only trees that have lifespans reaching into four-digit territory. Cypress trees (Cupressus sempervirens) often live for extraordinarily long times; a 4,500-year-old specimen called Cypress of Abarkuh is currently growing in Iran.

A few European yews (Taxus baccata) are also very old; estimates of their exact age vary between 2,000 and 5,000 years. At least one olive tree (Olea europaea) growing in Greece is known to be at least 2,000 years old, and many contend that it may be more than twice this age.

Although relative youngsters, sacred figs (Ficus religiosa) also reach advanced ages, although most of the oldest documented specimens are in the 2,500-year-old range. Several Japanese cedars (Cryptomeria japonica) have also reached ages in excess of 2,000 years.

A number of other species routinely reach 1,000 to 2,000 years of age, but the vast majority of tree species have much shorter average lifespans. Many, including a number of fruit trees, only live for a few decades at best. And while this seems like a negative attribute when discussing trees that have been around since the construction of the pyramids, short-lived species can be quite useful in some applications.

An Important Caveat: Clones Cause Confusion

While the unnamed bristlecone pine referenced above is considered the oldest living tree, an 80,000-year-old aspen grove is growing in Utah at this very moment. Unlike run-of-the-mill tree clumps, this grove is primarily represented by a single organism – an organism that has lived for this entire time.

While the bristlecone pine (and other long-lived species mentioned above) is a single stemmed tree, aspens grow as huge colonial organisms connected by a single, interconnected root system. While the individual stems (which you’d normally think of as individual trees) live relatively brief lives, the root system persists and produces new stems to replace those that die.

A similar example of a colonial species with a long lifespan is a Norway spruce growing in Sweden. Although the trunk that stands today isn’t the same one that initially erupted from the ground, the tree’s root system is about 10,000 years old.

***

Of course, even long-lived species don’t always enjoy lengthy lives – a variety of factors can shorten the lifespan of an individual tree. But if you take good care of your trees and have them inspected regularly by an experienced arborist consultant, you can give them a great shot at a long, healthy life. If you’d like to give your trees the best chance of living a long and healthy life, give your friends at Evergreen Arborist Consultants a call. One of our arborists will inspect your trees and provide tips for supporting them in the most beneficial way possible.

Who knows? Maybe one of your cypresses or pines will still be standing thousands of years from now.

life expectancy of deciduous, coniferous and fruit trees

Some trees adorn our planet for only a few decades, others live for thousands of years. With the deterioration of the environment, the life of trees is reduced. We will learn how many trees of different species live, and how to determine their age.

How long do individual tree species live?

First, let's find out how long trees live under favorable conditions - if the tree grows in “its own” climatic zone, without experiencing adverse effects.

Maple

Maple can live up to 400-500 years. In Russia, such centenarians are rare. So, for example, the life expectancy of the ash-leaved maple, imported from North America, does not exceed 100 years. A spreading tree with conspicuous leaves of an artsy shape.

Maple seeds can spread very far – two-winged fruits, falling, begin to rotate and, picked up by the wind, fly away.

The height of maple stands reaches 15-20 meters.

Beech

Beeches live 400-500 years. Widely distributed in European forests. Characteristic features:

  • smooth trunk, which reaches a width of 2 m;
  • maximum height - 30 m.

The tree grows slowly, but lives long. The beech has fruits that look like acorns. Moreover, they appear only in trees that have reached 40-50 years of age. The "beech nuts" have a unique ability to regulate metabolic processes.

Poplar

Poplars have been growing in nature for about 1000 years. This tree is actively planted in cities and along roads. If poplars have to grow in an unfavorable environment, they live less - 60-70 years.

Poplars are often seen in industrial areas - they are planted here because of their ability to absorb radiation and harmful substances.

The height of poplars with columnar trunks reaches 35 meters. Leaves are rounded. Poplar is a dioecious plant, there are female and male individuals. It is female trees that are the source of fluff, which causes allergies in many townspeople.

Oak

Oak lives up to 1000 years. This is a well-known long-liver in our area. In Russia, pedunculate oak (Quercus robur) grows predominantly. There are approximately 600 varieties in the oak genus. Oak is easily recognizable by its powerful trunk and spreading crown. Oak can also be unmistakably identified by the following features:

  • a figured leaf of a uniquely beautiful shape;
  • the original fruit is an acorn that wild boars and pigs love.

The tree is distributed throughout Europe. Oak wood is valued in furniture production.

Hornbeam

Hornbeam lives for about 300 years. It grows in Europe, less in Transcaucasia and Asia Minor. Has a wide crown. Likes to grow in shaded deciduous forests. Growth is very slow. Belongs to the birch family. The leaves serve as excellent fodder for livestock. The fruits of the hornbeam are used to obtain oil. The height of the tree is up to 30 m.

Linden

Linden lives on average 300-400 years, in some cases it can live up to 1000 years. Many varieties of linden grow in Russia - Amur, Caucasian, large-leaved. European linden can reach 40 meters in height. This beautiful tree is a source of lime blossom, which is actively used in cosmetology and medicine. Wood is easy to process - due to the softness of the fibers, it is an ideal raw material for carving.

Birch

The life span of birches is 100-150 years. If conditions are favorable, a tree can live 300 years. The birch distribution area stretched from French lands to Altai. The most common species is the warty or weeping birch (Betula Verrucosa). Average indicators of birch:

  • height - up to 45 m;
  • trunk girth - up to 1.5 meters.

The tree has several dwarf subspecies.

A young tree has a completely smooth, light brown trunk. Its famous trunk color - white with black stripes, birch acquires only after reaching 8 years of age.

Birch leaves are small, in the form of rounded triangles, the edges are serrated.

Ash

The average lifespan of an ash is 500 years. Its fruits are in the form of lionfish, falling in winter. It has a sparse leafy cover that transmits the sun's rays well. Features:

  • tree height - up to 30 m;
  • trunk width - up to 1 m;

Ash wood has a special strength, so it is valued in construction. Ash bark, its fruits and wood juice are used in medicine.

Elm

On average, elms live up to 300 years. The tree can grow as a shrub. Young trees have smooth bark that hardens with age. The leaves are elongated, the seeds are lionfish fruits. The height of the elm is up to 40 m.

It grows on plains and hills, in shady places and in open sunny wastelands.

Chestnut

Chestnuts live from 200 to 300 years. Differs in original flowers and leaves. The height of the chestnut is up to 35 m. The inflorescences are in the form of cones. In autumn, the fruits ripen - they are in a spiny box. Based on the fruits, painkillers are made.

Aspen

Lives on average 80-90 years, rarely lives up to 150 years. It has a columnar trunk. It reaches a height of 35 m. In diameter - up to 1 m. It burns poorly - it is not valued as a fuel.

Alder

The life span of an alder is about 100 years. This is a unique tree that can improve the soil - it is enriched with nitrogenous fertilizers. Raspberries and other shrubs grow well near the alder. Height - up to 20 m.

Pine

A tree lives on average up to 600 years. This is one of the most common trees in the forests of Europe and Russia. Widespread varieties of pine:

  • Siberian pine - lives up to 500 years;
  • European cedar - lives up to 1200 years.

Scotch pine (Pinus sylvestris) covers more than 20% of the territory of the former USSR. Its height is from 20 to 40 m.

Spruce

Lives from 600 to 1200 years, depending on the species. Grows all over the world. There are species that grow in a certain area. They reach a height of 50 m. It has a cone-shaped crown. Seeds appear on the 20th year of life - they are contained in cones.

Fir

Lives on average 300-400 years. Can live up to 700 years. A coniferous plant with vertically growing cones. The tree is evergreen. The needles do not fall off even after the branches have dried. The height of the fir depends on the species.

Yew

Lives from 1500 to 2000 years. Under favorable conditions, it can live 3000-4000 years. Yew berry grows very slowly. Height - 10-20, sometimes up to 28 m.

Thuja

Thuja lives 150-200 years. It is classified as a coniferous plant, but it does not have needles. This evergreen tree is undemanding to soils, so it is one of the most popular ornamental plants. It reaches a height of 2. 5 m. The folded or giant thuja can grow up to 6 m in height, the western thuja - up to 20 m.

Juniper

On average, junipers live 200-300 years. There are juniper species that live 500 years or more. Height and lifespan vary by species. Maximum height - 8-12 m.

Apple tree

Life expectancy - from 100 years, depending on the species. This tree is:

  • fruit;
  • decorative;
  • wild.

Maximum height - 15 m, there are also low-growing shrubs among apple trees. Trees vary in frost hardiness and moisture requirements.

Pear

Lives an average of 70 years. Some species can live up to 150 years. Fruiting continues up to 50 years. There are approximately 60 species. Height - up to 20 m. Does not like to grow in places with a high level of groundwater. In order for a tree to live longer, it should be planted on hills

Plum

Plum lives no more than 20 years. The tree bears fruit already in the third year of life. Prefers moist soils. Doesn't like drafts. Reaches 15 m in height.

Cherry

Cherry life expectancy is 25 years. Does not happen above 10 m. Compact and productive. One cherry brings up to 20 kg of fruit. Lives up to 5 years longer in the wild.

Cherry

This thermophilic tree lives 25-30 years. Much sweeter than cherries. Gives tasty and juicy fruits. It reaches a height of 8-12 m.

Apricot

Lives up to 100 years. It reaches a height of 5-8 m. It is not able to regulate fruiting - because of this, there is an overabundance of fruits. Drought resistant.

Rowan

Lives 50-80 years. It happens that some individuals live up to 200 years. It has 190 species. It comes in tree and shrub form. Height - 8-12 m.

How to find out the age of a tree?

Receiving energy from the sun, trees grow at different rates - depending on solar activity. There are two ways to determine the age - accurate and inaccurate, consider both.

Precise - by annual rings

To determine the exact age of a tree, it must first be cut down. Let's see why.

The trunk is expanded by the cambium, a special tissue that creates cells in both directions - inside the trunk and out. How the cambium develops depending on the season:

  1. Spring. Cambium produces cells characterized by large width and narrow walls. Such cells deliver nutrients more efficiently. Fabrics formed in spring have a lighter shade.
  2. Autumn. Cambium at this time of the year produces thick-walled cells, giving the wood increased strength. The autumn layer differs from the spring layer in a darker color.

By the number of stripes - light and dark, you can find out the age of the tree. To accurately determine the number of years lived, experts use:

  • a microscope;
  • colorants.

If the dark stripe is wider than usual, it means that the tree survived a cold autumn and a long winter this year.

By the number of dark and light rings, you can determine:

  • how old the tree is;
  • in what climatic conditions the tree grew.

Inaccurate - by indirect evidence

But how to find out the age of a tree without cutting it down? In this case, a calculation based on statistical averages is used:

  1. Determine the circumference of the trunk at a level of 1.5 m from the ground.
  2. The resulting value is divided by 3.14 - the number "Pi". The result is the barrel diameter.
  3. The diameter is divided by the value of the average annual growth of a particular tree in the study region.

The result obtained is not accurate, the error may be 20-30%.

Tables of life of trees

The average life expectancy of some deciduous trees are given in table 1.

Table 1

The main factor affecting the life of a tree is its appearance. So, fruit trees live the least - their life span is calculated in decades. But deciduous and coniferous trees can live for hundreds and even thousands of years - they are the basis of the "evergreen" forests of our planet.

Coniferous trees

Coniferous trees have a longer life span than their deciduous counterparts. Reasons for longevity:

  • Representatives of coniferous species tolerate harsh climate more easily.
  • Unpretentious in relation to the soil. Can grow on poor sandstone and clay soils.
  • Due to the branched root system, coniferous trees are hardy - they absorb water well from the soil.
  • Due to the special shape of the crown, they get maximum solar energy even at high growth density.
  • Needles, unlike leaves, have a small surface area and are covered with wax - this helps to retain moisture in it.

The following factors can influence the lifespan of coniferous trees:

  • Genetics. Each plant has certain adaptation possibilities.
  • Soil characteristics - much less impact than deciduous tree growth.
  • Humidity and temperature has little effect - coniferous trees grow in their usual environment. Only global climate change can affect their lifespan.
  • Location - plains, slopes, mountains. It depends on the strength and direction of the wind.
  • Forest density - coniferous trees are minimally affected, as their crowns are adapted to difficult conditions.
  • Diseases and pests . Fungal and bacterial infections can drastically shorten the lifespan of any tree.

Deciduous trees

The lifespan of deciduous trees can vary greatly even within the same species. The following factors can influence the lifespan:

  • Soil characteristics - its density, composition, saturation with nutrients and microelements.
  • Climatic conditions - humidity, average annual temperature, wind strength and direction, other indicators.
  • Neighborhood - how close neighboring trees grow. If the growth density is high, then only the strongest individuals live long.
  • Insects and other pests.
  • Location - natural or urban environment. It is clear that in a city where the air is polluted, trees live less.

Fruit trees

The life span of fruit trees is affected by:

  • Type of fruit tree.
  • Soil quality and nutrition.
  • Pruning, treatment, winterization and other care activities.
  • Destruction of pests, especially bark beetles, which are capable of destroying a tree in a couple of years.

Why do fruit trees have such a short life despite increased care? Large yields are expected from fruit trees. By artificially accelerating the growth of a tree, a person forces the tree to spend its resources - having used up its reserve of strength, it weakens ahead of time and dies.

How long do trees live?

It is interesting to know how long a tree lives. The Internet is literally full of such questions. And most often they are interested in how long fruit trees live.

Even children know how to determine the age of a tree: you just need to count the number of annual rings on the cross section of the trunk. However, it is not easy to collect data on the record age of trees of each species.

The easiest way to see cuts is when harvesting commercial timber. However, the age of a mature tree and the age limit are significantly different values. No one dares to cut down an old tree. All nations have a respectful attitude towards old trees. For example, in the USA, old sequoias and mammoth trees - sequoiadendrons - are even given their own names.

How do you know the age of a tree without cutting it down? To do this, you can use the so-called carbon method. Here is its meaning. In a growing tree, a rather complex metabolism takes place. In particular, trees absorb carbon dioxide and extract carbon from it for their growth. At the same time, it turns out that this carbon contains a fraction of its radioactive isotope 14C, which has exactly the same chemical properties as ordinary carbon, but a slightly larger mass of the nucleus. Atoms of a radioactive isotope are formed from atmospheric nitrogen when it absorbs slow neutrons produced when cosmic rays bombard the earth's atmosphere. Since the concentration of nitrogen in the atmosphere and the intensity of the bombardment are constant in magnitude, the proportion of radioactive carbon in the atmosphere is also constant. In the body of the tree, radioactive carbon begins to decay, turning into ordinary. Therefore, there is less radioactive carbon in old layers of wood than in new ones. This decay on a human scale of time is not going fast. For 5730 years, its concentration is halved. However, the difference in concentration between the core of the tree and the outer layers can be reliably measured if the sample is carefully drilled. So you can find out the age of the tree without damaging it. Archaeologists do the same when studying wooden structures.

Here are the estimates of the limiting age of various trees obtained for centenarians. Giant trees live the longest.

The Australian eucalyptus lives between 8,000 and 10,000 years. The bristlecone pine, which grows in the southwestern United States, and the mammoth tree, the sequoiadendron, live for about 6,000 years.

Sequoia, named after the Indian chief who invented writing, lives up to 4,000 years. Baobab and yew live the same amount. Juniper - up to 2000 years, cedar - up to 1500, plane tree - up to 1000.

As for our native trees, the times here are more modest, but also very impressive.

Oak - 1000-2000 years, spruce and linden - up to 500, elm - up to 400, pine - up to 350. Rowan lives up to 200 years, birch - up to 150, poplar and aspen - up to 100, willow and viburnum - 50 - 60 years.

The life span of fruit trees, unfortunately, is short: usually it is several decades.

Often trees do not live up to the time allotted to them by nature. So let's take care of them.
