"Trees straight underpin nan endurance of truthful galore type – including galore recovered connected nan IUCN Red List. Thriving, people divers forests are basal successful mitigating some ambiance alteration and biodiversity loss, and arsenic specified solutions for 1 situation often person mutually reinforcing benefits for nan other," said Dr. Dave Hole, vice president for world solutions astatine Conservation International's Moore Center for Science. "This makes nan increasing number of threatened character type included connected nan Red List each nan much troubling. Without biodiverse ecosystems that see patient and divers character populations nan world will look an moreover greater ambiance threat than nan 1 we are already facing."

People are besides economically limited connected trees. According to IUCN, much than 5,000 of nan character type connected nan Red List are utilized for timber successful construction. Over 2,000 type are utilized for medicines, nutrient and fuels.
