Cuts to Medicaid and frozen funding for broadband are both likely to have a negative impact on rural healthcare, which is already struggling. Plus, lawsuits over the mass firing of federal workers have huge implications for public lands.

SD grasslands might be more vulnerable to drought than other regions

Grasslands are considered a vital component of South Dakota's landscape. But on the heels of new research, an expert suggests they might not fare as well if the rate of drought patterns keeps intensifying.

Scott Collins, a University of New Mexico biology professor, helped co-author a new study that compared grasslands in North America and China, and their ability to recover from a drought. He said the areas they looked at in the United States performed better, despite some being in drier climates.

However, Collins warned that research is still evolving, and said if a warming planet produces more droughts, this is something grassland-heavy regions need to pay close attention to.

"Grasslands are underappreciated. They store a lot of carbon, they harbor a lot of biodiversity," he said. "We really need to think about their future under the climate regimes we're anticipating."

Research authors have said these findings could have broad implications for land management practices under the threat of climate change. Collins said South Dakota's grasslands are more comparable to China's than to the southern Plains states they studied. That means their productivity might suffer more if future drought predictions are accurate.

Collins said the group of researchers who teamed up for this project looked at impacts based on just one drought cycle. No matter how sensitive a grassland is to these conditions, he said, prolonged stretches of no rain -- with few gaps in between -- will eventually overwhelm the vegetation.

"As that happens," he added, "then you'll see a dramatic decline in production, and probably substantial changes in the composition of those grasses. "

Grasslands also contribute to agriculture, especially for livestock grazing. Such groups as the South Dakota Grasslands Coalition are working with area farmers to prepare for these scenarios. That includes tips from experts on how to better manage cattle on drought-stricken lands.
