American scientists have found that large trees, the “long-lived pioneers,” make a great contribution to reducing carbon in the atmosphere and increasing biomass. This confirmed their significant role in forest growth and protection.
The long-lived pioneers are mahogany, Brazilian walnut trees and pentander Seib. They grow much higher than others in the forest, according to researchers at the University of Texas, reports the Guardian.
“This analysis shows that differences in the growth, survival and reproduction of tropical forests are important for predicting carbon accumulation in forests,” said Caroline Farrier, associate professor of Integrative Biology at the University of Texas (Austin, USA).
Scientists have divided 282 tree species into 5 groups of growth, reproduction and life expectancy: “fast” species (fast growing and dying fast), “slow” (growing slowly and living long), “giants” (living long and breeding long) and “Fertile dwarfs” (small shrubs and low trees, grow slowly, die young, but give many offspring).
The results of the study will allow us to create a model for the restoration of adjacent young forests, particularly tropical, which are actively harvested.
It should be noted that the experts analyzed the satellite data from 1982-2016 and found that during this time the area with forests in deforestation increased on the Earth. Trees have become larger in mountain ecosystems but smaller in arid and semiary. The destruction of trees causes negative effects on the nature of the Earth, so as a result of deforestation, koalas can disappear in the world.
