Got a problem - Get an insect to eat it?

I was really set back by this article where insects are being used to fight a loosing battle to remove Tamarisk from the Colorado River. The very same method could be used to remove endangered species from wilderness study areas. Without the endangered species card to play no reason to restrict anyone or anything from using the area! Just a thought.

Of course these little critters will sooner or later be there anyway. What is that TV show called? After Man or when man is gone? Plants and insects eat New York City. Cogon.

Wilderness Weed of the Week

Nut Grass or purple nutsedge is the Wilderness Weed of the Week. He's a survivor and will be around for a very long time. The root system and tubers provide all the ground running ability needed to cover miles and miles of pristine wilderness. The seeds are very productive also. Some say this is the number one weed in the world but that's for another days comparison.

Seeds and tubers are very easy to find for study because this guy is everywhere in most states.
