AoR 24: Matt Germino, Bunchgrass Roots Fight Cheatgrass The Art of Range
-
- Science
Perennial bunchgrass roots are the prize fighter in the wildland boxing ring with cheatgrass, and bacteria may be sitting this one out. Matt Germino, range scientist with the US Geological Survey in Idaho, describes recent research on how bunchgrass roots compete with invasive annual grasses below the soil surface. We discuss concepts of resilience and resistance, the ecological mechanisms involved in competition, monitoring measurements that are good indicators of root dominance, and eventually discuss discouraging research on Pseudomonas flavescens, the bacterium hoped to be a silver bullet against cheatgrass.
You can find more information on the research discussed here at the USGS Forest and Rangeland Ecosystem Science Center website: https://www.usgs.gov/centers/fresc
And you can reach Matt Germino at mgermino@usgs.gov.
