 All of us are familiar with the phrase, tip of the iceberg, with the notion that ice floats and most of it's underwater and where we can't see it. And so it is with many of our rangeland plants. Sagebrush, for example, as shown here in this cut, has a very, very deep root system. Much of this plant is underground, most of it. And that deep root system allows it to capture water that's deep in the soil profile. But Sagebrush has also a very shallow, wide-spreading root system, allows Sagebrush to efficiently gulp up whatever water comes even in late summer rain showers that don't amount to much. So either way, whether it's deep soil moisture or shallow moisture, Sagebrush is very competitive for it and it counts for one of the reasons that Sagebrush is very abundant in Wyoming. So when you're driving around Wyoming, just remember that when you look at Sagebrush you're just seeing the tip of the iceberg.
