South Dakota grasslands are currently experiencing dry conditions, as shown in the mid-April 2025 Grassland Productivity Map released by the South Dakota Natural Resources Conservation Service (NRCS). This map, available under the “Range and Pasture” section of the SD NRCS website, is based on the SD Drought Tool, which calculates forage productivity using a two-year weighted average of precipitation and historical grass clipping data.
State rangeland specialist Emily Rohrer clarified that the tool is designed to assess grassland forage production, not cropland or forage quality. She emphasized that producers should factor in local conditions before making management decisions. A dry fall and an even drier winter have led to concern, but April through June remains the most critical period for rainfall in the region.
The outlook shows reduced productivity across much of the state, prompting the need for early planning. “Rainfall cannot be controlled, but being proactive and creating a drought plan is controllable,” said State Conservationist Tony Sunseri. “Visit the SD NRCS webpage to locate online tools and an office nearest you.”
Producers are encouraged to assess their grazing strategies. This includes reviewing which pastures were grazed last year and adjusting start times to allow for proper plant recovery. Giving pastures rest during the growing season helps build long-term resilience. Suggestions include combining herds, rotating more quickly through pastures, and providing longer recovery times for forage plants.
As precipitation trends remain uncertain, using the available tools and making adaptive management decisions will help producers protect grassland productivity through the 2025 growing season.
