About 17,000 species of trees are threatened with extinction, according to the report “The condition of trees in the world” published in Paris. The greatest threats are deforestation and deforestation. See the material of the magazine “Polska i świat” by Patryk Rabiega.

The report was prepared by the International Botanical Gardens Conservation (BGCI), which brings together botanical gardens and experts from the International Union for Conservation of Nature (IUCN). It shows that one third, or approximately 17.5 thousand species of trees, is threatened with extinction. The report was released in Paris on Wednesday. The research lasted five years, 60 institutions and 500 experts participated in them.

Even common trees such as magnolias, as well as oaks, maples and ebony trees are endangered species.

The role of forests in the ecosystem

We have already irretrievably lost 142 species of trees. “Many species are on the verge of extinction, some of them only have one tree,” warns Jean-Christophe Vie, director general of the Swiss-based Franklinia foundation, in the report. He believes that the still high level of deforestation is “shocking” as trees play a vital role in nature, providing habitat for many species of animals and plants, absorbing carbon dioxide and providing nutrients for some drugs.

Brazil, where much of the Amazon rainforest is located, has the most tree species (8847) and the most endangered (1788) due to intensive agriculture. However, the highest percentage of endangered species is found in tropical regions of Africa, particularly Madagascar and Mauritius, where 59 percent and 57 percent, respectively, are endangered. species.

“Tree species that have evolved over millions of years to adapt to climate change cannot survive an avalanche of human threats,” warns Jean-Christophe Vie in the report.

Climate change and forest ecosystems

Today it is human activity that is the main cause of tree die-off. They are cut for arable fields, animal husbandry or industrial areas.

“Climate change may become the main cause of the collapse of most, if not all, forest ecosystems,” wrote Adrian Newton of Bournemouth University in the report.

Global warming is therefore directly threatening over a thousand species, modifying their habitats, increasing the risk of storms, floods, wildfires and even disease.

For Jean-Christophe Vie, remediating forests to combat climate change is “an excellent opportunity to change that terrible picture.” But you have to make sure that the right trees are planted in the right place – emphasizes the researcher.

“If only we could learn to respect trees, the environment would undoubtedly benefit,” she notes.
