Driving through Nevada I heard a radio program that was discussing a real problem they are having with a non native grass. They called it Cheat Grass but the fire fighters are calling it gas grass. It seems that it is invasive and was introduced by Russian Immigrants. The problem is that it is prolific and during fires is almost explodes and can spread a fire very quickly. It is also one of the first to come back after a fire, crowding out other plants, setting the stage for the next explosive wildfire. They are studying ways to eradicate the stuff.Does it make the headlines when a non-native plant resists burning, or when a native bursts into flames readily?
Then there is always that other Russian import and noxious weed, Russian Thistle, better known as Tumbleweed. I have also heard what the Missouri DNR does if they find Twessle (sp) on your property. It was a plant imported to use in the wool industry.There's no tumbleweed here, but I'm familiar with it. How many miles away does the problem have to be happening in order to require changing your behavior as a result of it, to warrant a reactionary law against it in your locale? 500 miles? 1000 miles? One state away, in the case of the Oregon statute? That land mass (Oregon plus the states touching it) would be the tenth largest country on earth, if it were one, roughly.
