New research has provided the most accurate count yet for the number of trees on Earth: 3.04 trillion.
The finding, with 95% accuracy, is about eight times more than previous estimates, but suggests that the number of trees has plummeted 46% since the dawn of human civilization 11,000 years ago – with the number once being above six trillion.
The study, published in the journal Nature, was conducted by an international team of researchers and led by Yale University.
The tree count was made using a combination of satellite imagery and more than 400,000 ground measurements, with the researchers defining a tree as “a plant with woody stems larger than 10 centimeters [four inches] diameter at breast height.”
