Research at Rannells Ranch

“If we want to solve complex problems in grazing systems, we need accurate, system-scale measurements that let us understand how plants, animals, and the environment respond together.” -Eduardo Santos
Where Research Supports Range
Rannells Ranch is a working research ranch dedicated to advancing scientific understanding of grazing systems, rangeland ecology, and producer decision-making in the Flint Hills.
Through long-term field studies, applied research trials, and interdisciplinary exploration, the ranch generates knowledge that supports innovation adoption, strengthens management practices, and contributes to the sustainability of tallgrass prairie ecosystems.
2026 Rannells Ranch Research Plan
Pastures 2-16: These pastures will be dedicated to the start of a new multi-year experiment examining the influence of stocker arrival weights on animal performance and economic returns. Pastures will be stocked as “light” or “heavy” based on steer arrival weights and cattle will also be stocked on a head per acre basis or pound per acre basis.
NW, SW and E South Rannells Pastures: A subset of cattle grazing the southern ~1,300 acres of the property will be equipped with GPS collars for the grazing season. These collars will be used to manipulate cattle grazing behavior to look at the impact of animal density and grazing site on animal performance and rangeland health.
Student Research Opportunities
Undergraduate and graduate students have opportunities to assist with research or develop their own projects. Students help gather data, monitor pastures, and work with faculty on a variety of topics related to range. These hands-on experiences build practical skills for future careers.
Current Research Projects
Current work at Rannells Ranch includes grazing trials, rangeland monitoring, and research on how producers adopt new practices. Each project supports science-based management on working lands.
