Your coverage educating and informing people of the dangers of exotic invasive species is welcome in the battle to control and eradicate these non-native threats. Not all non-native plants become invasive, but the rapid proliferation of invasive non-native plants in our wildlands can have a devastating effect.

Even though some invasives may look beautiful to the eye, if unchecked they present a real threat to wild species diversity and degrade many natural areas. Invasive species are the No. 2 cause of plant endangerment in the U.S., forcing native species to the edge of extinction, and they also cost millions of dollars in damage to agriculture and infrastructure.

The Center for Plant Conservation has developed information about invasive species, including resources, contacts and proactive measures that will help prevent the introduction of new invasive plants. We invite Trib readers to visit our website at for additional helpful information.
