A global study organized and led by Colorado State University scientists shows that the effects of extreme drought – which is expected to increase in frequency with climate change – has been greatly underestimated for grasslands and shrublands.
It is the first time an experiment this extensive has been undertaken to generate a baseline understanding of the potential losses of plant productivity in these vital ecosystems.
Melinda Smith, a professor in the Department of Biology at CSU, led the study and was the first co-author on the paper with Kate Wilkins, the regional conservation director for Colorado at the Denver Zoo. She said the observed reduction in a key carbon cycle process after a single 1-in-100-year drought event greatly exceeds previously reported losses for grasslands and shrublands.
