The variety of woods in the world is impressive. Each species has unique characteristics that make it special, whether for its color, hardness, strength or specific uses. In this article, we will discover how many wood species exist, how they are classified and which are the most popular.
The diversity of wood species
There are an estimated 60,000 tree species in the world, according to data from the Global Tree Assessment. However, not all of these trees produce timber that is used commercially.
What defines a useful wood species?
For a timber species to be considered valuable in commercial or practical terms, it must meet certain characteristics:
Availability: It must grow in sufficient quantities.
Durability: Resistance to weather, moisture, insects and other factors.
Physical properties: hardness, density, flexibility and color.
Processability: Ease of cutting, sanding and treatment.
Of the 60,000 tree species, about 1,000-2,000 wood species are used in carpentry, construction, joinery and other applications.
Classification of wood species
Wood species can be divided into two broad categories:
1. Hardwoods (broadleaf)
Originating from broadleaf trees, they tend to be denser and more resistant.
The diversity of wood species depends on several factors:
Climate: The tropics are the richest region in terms of biodiversity, hosting the majority of timber species.
Soil: Soil properties affect wood density, color and growth.
Human use: Some species are protected due to overexploitation, such as ebony and mahogany.
Most popular wood species and their use
Although the variety of woods is wide, only a few are widely used due to their availability and characteristics. Here are the most popular ones:
Oak: For durable furniture and flooring.
Pine: For its low cost and ease of use.
Teak: Ideal for outdoors due to its water resistance.
Cherry: Appreciated for its smooth and warm finish.

Conclusion
The planet’s biodiversity offers us an impressive variety of wood species. Although there are more than 60,000 tree species, only about 1,000-2,000 wood species are regularly used in various applications. From hardwoods such as oak and walnut to softwoods such as pine and cedar, each has a unique purpose and value.
When choosing a wood species, it is important to consider both its properties and its environmental impact, prioritizing wood of sustainable origin.
FAQ: Frequently Asked Questions About Wood Species Diversity
How many species of trees exist in the world?
According to data from the Global Tree Assessment, there are an estimated 60,000 tree species worldwide. However, not all of these species are used commercially for timber production.
How many species of wood are used commercially?
Of the 60,000 tree species, approximately 1,000 to 2,000 are used in commercial applications such as carpentry, construction, and cabinetmaking. These species are selected for their physical properties and availability.
What characteristics make a wood species commercially valuable?
A wood species is considered commercially valuable if it meets certain characteristics:
Availability: Grows in quantities and sizes sufficient for sustainable exploitation.
Durability: Resistance to time, humidity, insects and other environmental factors.
Physical properties: Hardness, density, flexibility and color make it suitable for various uses.
Processability: Easy to cut, sand and treat in industrial processes.
How are wood species classified?
Wood species are divided into two broad categories:
Hardwoods (broadleaf): Coming from broadleaf trees, they are usually denser and more resistant.
Softwoods (conifers): Coming from needle-leaved trees, such as pines, they are usually lighter and less dense.
What are examples of hardwoods and softwoods?
Examples of hardwoods include walnut, cherry, and oak, known for their strength and durability. On the other hand, softwoods such as pine, cedar, and fir are prized for their ease of work and lightness.
What factors influence the variety of wood species?
The variety of wood species is influenced by factors such as climate, soil type, altitude, and the biodiversity of each region. These factors determine the physical characteristics and availability of the different species.
Which regions of the world have the greatest diversity of wood species?
Tropical regions, such as South America, Central Africa, and Southeast Asia, boast a great diversity of wood species due to their climate and biodiversity. These areas are home to a wide variety of trees with unique properties.
What common uses do different species of wood have?
Wood species are used in a wide range of applications, including construction, furniture making, carpentry, cabinetmaking, and musical instrument production. The choice of species depends on the properties required for each specific application.
Why is it important to know the different species of wood?
Understanding the different wood species is crucial for selecting the right type for each application, ensuring durability, aesthetics, and sustainability. It also allows for informed decisions in construction and design projects.
