British scientists report that about half of the trees planted as part of the restoration of tropical and subtropical forests are dying. They published their findings in the journal Philosophical Transactions of the Royal Society B. Nevertheless, they emphasize, active afforestation plays an important role in restoring this ecosystem.
Calculations by the research institute UK Center for Ecology and Hydrology show that around half of the trees that are planted as part of tropical and subtropical forest restoration die within a few years of planting.
The study looked at 176 places in Asia where natural forests had been affected by human activity. The team of scientists found that, on average, 18 percent of the trees planted died within five years and 44 percent after five years. The chances of survival depend to a large extent on the place of planting and on the species. In some jobs, the first five years can survive up to 80 percent. trees, on others – a similar percentage dies. Forest restoration is an important part of the fight against biodiversity loss and climate change. Forests trap carbon dioxide and create natural habitats for many species.
An international team of nearly 30 research centers found that when an area was completely deforestation, reforestation was less successful compared to where some trees were left. Interestingly, trees planted in areas where old, mature trees still grow were about 20 percent more likely to survive. Scientists emphasize that active afforestation makes nature regenerate faster. Areas where active afforestation was carried out regenerated more dynamically than those where it was not.
