In Bonner County and across Idaho, noxious weeds are doing bad things ranging from displacing desirable plants to lowering property values.
Through most of antiquity plants moved very slowly across the landscape
(they don't have legs, after all).
This was especially true for plants in harsh environments that had to become really aggressive just to survive. They not only had to fight off the climate and each other, but microbes, insects, and animals. Meanwhile, the microbes, insects and animals in their vicinity fought right back with their own adaptations which limited the spread of plants. The plants got tougher and developed amazing abilities to stay alive.
Fast forward: humans grew ever more mobile over the past five or six centuries. They moved tough plants (giving them legs), both accidentally and on purpose, over long distances to totally new environments. There were opportunities for those plants to live with minimal controls. Maybe the climate wasn't as harsh; probably there were no microbes, insects, or animals with an appetite for these new plants. The native plants couldn't compete. That is when once was just a pretty flower became a war criminal. It invaded, multiplied, and took over its new home, crowding out the native plants, landscaping and crops.
The bad things began to happen.
