New Invaders
The most cost effective and environmentally friendly way to control invasive weed species is to prevent them from gaining a foot-hold on the land. That is why the Land Operations/Range program focuses much time and effort on preventing new weeds from spreading. It is far less expensive to treat a small patch of weeds, before it becomes larger and harder and/or impossible to control.
