Briefings

A July 2026 Nature Communications study published in 2026 found that diverse forests in U.S. woodlands better withstand compound climate extremes like heat and drought. Lead author Xuetao Qiao, a postdoctoral researcher at Peking University, noted initial uncertainty in detecting this relationship in real forests. The study examined thousands of acres of U.S. woodlands and compared five tree species at the 25-year-old Sardinilla plot in Panama, which is the oldest tropical tree diversity experiment. The research contrasts with previous studies focusing on single heat waves rather than compound events.

Key points

• A July 2026 Nature Communications study found that diverse forests in U.S. woodlands better withstand compound climate extremes like heat and drought.
• The study examined thousands of acres of U.S. woodlands and compared five tree species at the 25-year-old Sardinilla plot in Panama.

Context

Forests around the world face mounting pressures as the climate changes. Previous research had already shown that diversity among tree species, broadly, made forests stronger, but most of this research had been smaller in scale or on human-planted experimental plots. This study confirms that diversity does indeed have a positive effect on the vast, complicated systems of natural forests somewhat surprising the lead author, Xuetao Qiao.

Limitations

The study was published in July 2026 in Nature Communications and examined thousands of acres of U.S. woodlands. It focused on compound climate extremes like heat and drought rather than single events. The Sardinilla plot reached 25 years in 2026, making it the oldest tropical tree diversity experiment. The research is based on limited evidence regarding global forest systems and may not fully capture all regional variations.
