The Tricky Business Of Cutting Back Invasive Plants

Walter Siegmund/Wikimedia

The Eastern Oregon landscape stretches out to the horizon, an area some people call "the sagebrush sea." 

But it's not all sagebrush... non-native grasses and the native but opportunistic Western Juniper are causing fits in many places, encroaching on the native grasslands. 

Landowners are spending time and effort cutting back the juniper, but new research shows their efforts can be for naught if they leave the juniper cuttings behind.  Researchers Jacob Dittel, Lisa Ellworth, and Dana Sanchez pay us a visit.
