Time to Re-Visit Drought Plans for the Ranch: May 2017 Update

 

Recent rainfall across South Dakota has eased drought concerns in some areas of

the state. However, other areas are still at risk and ranchers need to keep a close eye on rangeland conditions and update their drought plans.

 

 

The South Dakota Natural Resources Conservation Service (NRCS) current grass production estimates and projected peak grass production estimates for May 1, 2017 (Figure 1 and Figure 2) indicate improved conditions compared to last month.

 

 

The NOAA Climate Prediction Center also predicts a wetter period for the next 3 months (Figure 3). However, SDSU Extension State Climatologist Laura Edwards cautions, “The North Central Region is still half or less of average rainfall in the last two months.” For more information, see Summer Season Climate Outlook 2017. 

 

 

As mentioned before, April, May, and June are critical months for precipitation and

grassland production in the Northern Plains. By July 1, 75% to 90% of vegetation growth has been completed (Gates). Ranches in South Dakota that received half or less of average rainfall by this point (May 24, 2017) should be implementing management actions within their drought plan and adjusting stocking rates. For example: delaying turnout, culling cows, running no yearlings, moving animals to other areas in the state if possible and cost effective.
