Trees are crucial living components and help balance the ecosystem, explaining why experts work tirelessly to discover how many tree species are there.
Because the answer is a lot…a whole lot. And, new species are being identified all the time.
Thanks to technological advancements in the research world, scientists can now provide a pretty good estimate of how many tree species are there on the planet and how many trees are in the world.
This guide outlines 60 of the most common tree species and explains how experts determine how many tree species there are and the types of trees in any given location.
How Many Tree Species Are There?
The last decades have seen impressive tech advancements in research, and now scientists can use systems like satellites to enhance their studies of living organisms. There are more professionals conducting studies and using more resources.
The rough estimate of all the tree species in the world currently stands at 65,065, distributed in all countries worldwide.4 Other research papers also estimate that the number may be as high as 73,000, but more work is necessary to update this information.
You can find various updated databases listing all the accounted-for tree species. However, one challenge to overcome is that scientists are yet to identify all the species in the world, and the tally may be higher than the recorded 65,065.
Identifying the different types of trees in the world would help reforestation activities as advocates would have a better idea of the type of trees to plant that would help the ecosystem in a specific area.
How Many Types of Trees Are There? 4 Main Tree Types
Trees globally fall into four categories: deciduous, evergreen, angiosperms, and gymnosperms.
Deciduous Trees
Because of its climate, the U.S. has different types of deciduous trees, including maple, oak, and elm. They lose their leaves yearly to retain their food and water supply through harsh conditions like winter.
Most have massive leaves to facilitate photosynthesis, and shedding them relieves the plant of the expensive water loss in readiness for winter. Still, they grow back when the conditions are more favorable.
Evergreen Trees
Unlike deciduous trees, evergreens stay intact all year round, although new leaves grow in place of the old ones.
Most of them live in tropical rainforests, and the country’s common types of evergreen trees include the hemlock, eucalyptus, and cycads.
Angiosperms
Fruit trees like apple and mango trees are angiosperms that grow flowers that develop into fruit with seeds.
The flowers are their reproductive systems, and the plants rely on animals to reproduce.
Gymnosperms
These tree species don’t have flowers, but their seeds are open for pollination by wind. They are typically softwood plants with seeds growing on cones or leaves.5
The most common gymnosperms include the pine and fir tree varieties.
How Many Species of Trees Are There?
There are more than 65,000 tree species on the planet, and scientists are yet to discover thousands more. The following are some popular types of trees with pictures and identifying features to give you a clear picture of the diversity of plants.

How To Identify Different Kinds of Trees
There are two main ways to categorize trees, using their leaves and seeds. Identifying the types of tree leaves will help you distinguish deciduous from evergreens because the former’s leaves shed seasonally as the plant prepares for winter.
However, evergreen varieties stay intact through the year and grow in tropical rainforests where they don’t have to shed their leaves. The seeds or grains can also help you identify the tree species because there are flowering and non-flowering plants, angiosperms, and gymnosperms.
Flowers or fruits on the tree mean that the plant is an angiosperm that depends on animals for fertilization. On the other hand, if you see cones, fur, or exposed seeds instead of flowers, you can categorize the tree as a gymnosperm that relies on wind for pollination.
How Many Kinds of Trees Are There in America? How Many Tree Species Are There in America?
Suppose you are wondering how many trees are in the United States. In that case, America is home to more than 1,000 different types of tree species, with the most common variety being the red maple, and the oak is the national tree, signifying strength and adaptability.1
Out of the over a thousand varieties, the country’s most popular types of trees include the sweetgum, Douglas fir, sugar maple, flowering dogwood, balsam fir, quaking aspen, white oak, and bull pine. The climate in North America favors the growth of these trees, spread all over the country, growing in the forests and on private properties.
Estimating Tree Species Extinction Risk in the Brazilian Amazon
Estimating the range sizes of Amazonian tree species helps scientists understand the biodiversity in the rainforest. Their findings concluded that the tree species have enormous ranges and are about 300 years old on average, especially in the more fertile parts of the region.
The Brazilian Amazon is quite massive, but the country is still dealing with a higher deforestation rate than any other tropical country. The forest keeps shrinking, adversely affecting the tree species in the area.
The deforestation rate in the Amazon is at 0.7% annually, leading to a high risk of tree species extinction. Experts rate a 16- 36% risk of death of certain trees based on the particular deforestation rate of various parts of the rainforest.
Earth Has Tree Species More Than You Think
Despite the high-tech systems scientists use for their findings, there is still a long way to go before they account for all tree species in all forests worldwide. While data states that there are over 65,000 different tree varieties, chances are high that more than 14% more species are out there.
Besides, researchers still need to discover more than 9,000 more types. These unidentified species lie deep in tropical rainforest jungles and are rare, under serious risk of extinction due to climate change and massive land clearing.
When Was the First Estimation of Tree Species?
A research crew from the UK first compiled a list of the global tree species in 2017. The data came from 500 documents and featured more than 80 experts in work spanned two years.
Their findings established there are more than 65,065 tree species.
However, one challenge scientists must overcome is the unknown tree species problem, where there are still thousands of unidentified plants worldwide. It also applies to animal research making it impossible to list all the living creatures globally.
Researchers find it easier to identify tree species thanks to technological upgrades. Unlike in the last decades, they can confidently state that more than 65,000 various species are across multiple countries, continents, and climates.
The list is inexhaustible but notes that all these species fall into either of the four main groups, deciduous, evergreen, angiosperms, and gymnosperms. They all come together to form more than 3.5 trillion trees worldwide, with Russia having the highest tree population due to its massive landmass.
If you were wondering how many tree species are there, note that there are more than 65,000 different species but remember that scientists are confident that there are thousands of unidentified varieties all over the planet.
Frequently Asked Questions About How Many Tree Species Are There
How Many Different Trees Are There in America?
While there are over 3.4 trillion trees worldwide, America is in the top five countries with the highest number of trees. More than 228 billion trees grow in the country across various regions, and only Russia, Brazil, and Canada rival the population.
What Are the Types of Forestry Species Worldwide?
The forests are vital to the ecosystem since they cover almost 30% of the world’s land mass and host most of the earth’s biodiversity. There are more than 60,000 tree species in the forests, 80% amphibian population, 75% of bird species, and 68% of the earth’s mammals.
How Many Tree Species Are There in America?
North America is rich in biodiversity, and studies show that more than a thousand tree species call it home. The climate is favorable for their growth, and they have devised ways to adapt to extreme changes, like shedding their leaves during harsh winters.
How Many Species of Trees Are Out There?
The massive jungles and forests in the world are home to more than 65,000 tree species distributed across countries and continents. Researchers use technology to identify the various species in the world, but there is still a challenge of non-discovery of rare trees hidden in forests.
What Are the Two Main Categories of Trees?
The first category of trees is based on the leaves where deciduous trees shed them during winter, but the evergreens keep theirs all year round.
You can also classify trees based on their seeds or ability to flower where angiosperms grow flowers which later turn into fruits, while gymnosperm seeds are exposed and rely on wind pollination for reproduction.
