Trees Never Die of Old Age Naturally

While trees can die from disease, pests, drought, or human interference, there’s no biological expiration date for a healthy tree. Some trees, like bristlecone pines, are over 4,800 years old.

One Large Tree Can Provide a Day’s Supply of Oxygen for Four People

Trees absorb carbon dioxide and release oxygen. A mature leafy tree can produce enough oxygen for 2–4 people per day, making urban canopy vital for air quality.

Trees Can “Remember” Droughts

Research shows trees can alter their growth patterns based on past drought experiences, adjusting water usage in future years. It’s a form of biological memory helping them adapt to climate change.

Leaves Don’t Change Color Because of Cold Alone

Fall leaf color is triggered by a reduction in daylight, not just colder temperatures. As chlorophyll fades, the yellow, orange, and red pigments (always present) finally become visible.

Tree Rings Tell More Than Just Age

Each ring in a tree’s trunk tells a story. Wider rings indicate good growing seasons, while narrow ones can reveal droughts, fires, or insect outbreaks, making tree rings valuable for studying climate history.

Urban Trees Can Lower Neighborhood Temperatures by Up to 9°F

The shade and evapotranspiration from trees can cool city streets, reduce energy use, and combat the heat island effect. Planting trees is one of the most affordable ways to cool urban environments.

The Tallest Tree in the World Is Over 380 Feet Tall

A coast redwood named Hyperion, located in California, holds the record as the tallest known tree on Earth. It’s taller than the Statue of Liberty and still growing.

Trees Improve Mental Health and Productivity

Studies show that being around trees and green spaces can reduce stress, improve mood, and even boost memory and focus by up to 20%. It’s one reason tree-lined streets and parks are linked to healthier communities.
