Compared to gene-edited babies in China and ambitious projects to rescue woolly mammoths from extinction, biotech trees might sound pretty tame.

But releasing genetically engineered trees into forests to counter threats to forest health represents a new frontier in biotechnology. Even as the techniques of molecular biology have advanced, humans have not yet released a genetically engineered plant that is intended to spread and persist in an unmanaged environment. Biotech trees – genetically engineered or gene-edited – offer just that possibility.

One thing is clear: The threats facing our forests are many, and the health of these ecosystems is getting worse. A 2012 assessment by the U.S. Forest Service estimated that nearly 7 percent of forests nationwide are in danger of losing at least a quarter of their tree vegetation by 2027. This estimate may not sound too worr...
