Dogs trained to sniff out invasive plants

Dogs that have been trained to detect an invasive weed are better at finding the plants than humans, a new report says.

Invasive plant managers often face the tough task of wiping out an entire species from an area. But small or rare plants can elude notice, thwarting efforts at eradication. To track down those pesky hold-outs, researchers suggest, why not recruit dogs? After all, so-called detection dogs have been trained to find everything from land mines to cadavers.
