U.S. Forest Service and Chinese Academy of Sciences Enter into a New Research Partnership

On May 20, 2016, the U.S. Forest Service and Chinese Academy of Sciences jointly entered a scientific partnership. After years of sharing a mutual interest in urban forestry and ecology, the duo signed an official Letter of Intent declaring their new collaborative relationship.

Every year urban populations in the U.S. and China grow, increasing the need for a greater understanding of the natural aspects of a city (urban trees, wildlife, water) and how they interact with the social parts of cities such as clean water, climate resilience, or sustainable living.

Genetic Conservation Programs Can Help Protect Tree Species from Pathogens, Insects, and Future Climate Change

In today’s world of changing climates and unnatural human transport of pathogens and pests, a species’ survival relies on its adaptability more than ever. Easy-going temperaments and flexibility aren’t the types of adaptive natures a species needs. A species needs genetic diversity so that within its populations certain traits already exist that can help it adapt to and survive new threats. The U.S. Forest Service is a leader in realizing the need to conserve genetic diversity and operates genetic conservation programs to maintain it within tree species.

Scientists Draft a Natural Nemesis to Combat Invasive Tree-Killing Beetles

The emerald ash borer, an invasive beetle from Asia, is blitzing ash trees in urban and forested ecosystems across North America. To date, this metallic green beetle has attacked and killed hundreds of millions of ash trees in 25 states, and its spread continues. To control this beetle, the U.S. Department of Agriculture (USDA) is using biological control, a long-term sustainable management tool that involves the introduction of specialized natural enemies from a pest’s native region.


Tetrastichus planipennisi
This wasp, Tetrastichus planipennisi, is one of four species of natural enemies, or parasitoids, released to control the emerald ash borer in North America.
