Elephants Reverse the Depletion by Cattle of Soil Carbon and Nutrient Pools

March 24, 2020
Truman Young, Department of Plant Sciences, UC Davis, co-authored an article showing that megaherbivores (elephants) mitigate the negative effects of cattle on tropical African savanna rangelands, where wild herbivore populations are declining. He is project director of the Kenya Long-term Exclosure Experiment (KLEE), the most productive field experiment in Africa, and the site of this research.

Cattle Ranchers Cope with Dry Pastures (Video)

This winter’s lack of rain, up until mid-March, did not produce much forage for cattle, or carryover vegetation. Leslie Roche, Department of Plant Sciences, covers rangelands and pasturelands, and says this has been commonplace this winter. Many grasses are producing seeds earlier, leading to less vegetative growth.

Supporting First-generation Ranchers in Coping with Drought and Climate Change

Leslie Roche and colleagues tell how new ranchers confront drought. Climate adaptation is important in agricultural systems, but new ranchers aren’t able to benefit from information passed down from multi-generational ranching families. First-generation ranchers are often young, female, and diverse, with different goals and needs.
