Thirty-eight per cent of the world’s trees are at risk of extinction according to the first Global Tree Assessment, published in today’s update of the IUCN Red List of Threatened Species.

So, report has not been published yet, so I will mention in points all important part of this report.

1. For the first time, the majority of the world’s trees have been listed on the IUCN Red List, revealing that at least 16,425 of the 47,282 species assessed are at risk of extinction.
2. Trees now account for over one quarter of species on the IUCN Red List, and
3. the number of threatened trees is more than double the number of all threatened birds, mammals, reptiles and amphibians combined.

This comprehensive assessment presents the first global picture of the conservation status of trees, which enables us to make better informed conservation decisions and take action to protect trees where it is urgently needed.

1. The highest proportion of threatened trees is found on islands.
2. Island trees are at particularly high risk due to deforestation for urban development and agriculture at all scales, as well as invasive species, pests and diseases.
3.  Climate change is increasingly threatening trees, especially in the tropics, through sea-level rise and stronger, more frequent storms.
4. The IUCN Red List also shows that the loss of trees is a major threat to thousands of other plants, fungi and animals.
5. As a defining component of many ecosystems, trees are fundamental to life on Earth through their role in carbon, water and nutrient cycles, soil formation and climate regulation.
