Forage Production Models and Predictions for Semi-arid Grasslands with Markéta Podebradska
November 30 @ 3:00 pm - 4:00 pm
Livestock producers, especially in semi-arid areas, often have to deal with a high interannual forage production variability caused by fluctuations in precipitation and by drought. There are certain management strategies that livestock producers can utilize to mitigate losses connected to drought. These include, for example, the use of flexible stocking, buying additional feed, or relocating livestock to different pastures. However, there is uncertainty connected to these decisions: When is the right time to implement these? How much forage will there be if it continues to be dry? What are the conditions elsewhere? This presentation will introduce some of the existing methods for estimating and predicting the amount of annual forage using remotely sensed data and statistical and ecological modeling. Results from Nebraska Sandhills case study and ongoing research on modeling the forage production in the western United States will be presented.
Markéta Poděbradská is a Ph.D. candidate in the School of Natural Resources, specializing in Climate Assessment and Impacts. Markéta comes from Prague, Czech Republic, where she obtained her Bachelor’s degree in Applied Ecology from the University of Life Sciences in Prague. She currently works on developing annual forage production models and predictions for the western United States that is part of a project funded by the USGS.
