Scientists calculate biomass of largest trees on Earth.
The first three-dimensional map of California forests was created using the GEDI orbital laser radar on the ISS.
Using laser scanning, scientists have calculated the exact biomass of California redwoods – the largest and tallest trees in the world. The largest of them weigh about 110 tons.
During the study, scientists created the first three-dimensional map of California forests using the GEDI orbital laser radar on the ISS. These forests consist mainly of redwood (Sequoia sempervirens) – the largest coniferous trees on the planet, which can live up to several thousand years and reach a height of more than 100 meters.
Scientists have calculated the volume of trees, their biomass, as well as typical and maximum values for redwoods. For example, they found that the tallest and largest members of the species Sequoia sempervirens, can weigh up to 110 tons. In general, measurements showed that the total biomass of California coniferous forests was about 30% greater than scientists thought.
In the near future, scientists plan to use GEDI for similar research in other forests around the world.
Earlier, scientists concluded that growing up in a green environment, children have higher IQ levels. The study involved more than 600 children aged 10-15 years.
