New Zealand has one of the most well-developed forest biosecurity programs in the world. The logs pictured here at the Port of Tauranga were fumigated prior to export to minimize the chance of accidentally spreading forest pests. (U.S. Forest Service/Frank Koch)
Sometimes there is more to global trade than meets the eye. While consumers and economies may benefit from expanding market opportunities and a seemingly endless array of readily available goods, harmful pests could be lurking as people and products are transported between countries.
An international research network, including scientists from the U.S. Forest Service, has come together to share information about how exotic animals, diseases and plants can move and spread—and threaten agricultural and natural resources.
The International Pest Risk Mapping Workgroup consists of governmental and academic scientists from around the globe who study potential stowaway pests in order to assess the likelihood of their establishment in new locations and the impacts if and where they spread. Read more »

In forests, climate change ramps up stress already occurring from extreme weather events, disease and insect outbreaks, catastrophic wildfires, and invasive species. Resilient forests are better able to absorb stress without compromising the services they afford. In the same way that good sleep, healthy diet, and regular exercise make a person resilient (though not immune) to illness, forests can be helped towards resiliency by management practices that focus on sustaining or restoring ecological integrity in relation to future conditions. While neither the many threats to forests nor the management approaches available to abate them are new to forest managers, climate change introduces additional pressure and the need for the rapid translation of emerging science into forest management practice.
