Ecologists: Screen Plant Imports to Foil Invasives
University of Massachusetts Amherst

A new analysis suggests that climate change in the U.S. will boost demand for imported drought- and heat-tolerant landscape plants from Africa and the Middle East, greatly increasing the risk that a new wave of invasives will overrun native ecosystems in the way kudzu and purple loosestrife have.

Giant Weed Creates Threat to Our Nation’s Ecosystems—and Border Security
Allen Press Publishing

Weed control has become a matter of national security. Along U.S. southern coastal rivers, most particularly Texas’ Rio Grande, an invasive species of plant known as giant reed is encroaching on the water, overrunning international border access roads, and creating a dense cover for illegal activities. The U.S. Department of Homeland Security has called for a plan to control this weed.
