Trade ideas, seek collaboration: Rothamsted visit sparks scientific creativity

The creativity that sparks when people meet in person filled the halls at UC Davis’ Department of Plant Sciences when an international team of scientists from Rothamsted Research, U.K., visited recently. Farm tours and presentations gave way to high-energy discussions of wheat genetics, soil management, grazing practices, climate change mitigations and opportunities for future collaboration.

Working Rangelands Wednesdays: Ken Tate, June 3

Ken Tate, UC Davis and UC ANR, will address “Water Quality on Pastures and Rangelands” at the Working Rangelands Wednesdays webinar on June 3, 2020. The new series of biweekly webinars focuses on working rangelands in California and the West. Webinars are recorded and offered as podcasts.

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

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.

Release of Weevil for Biological Control of Yellow Starthistle

The USDA will allow the release of a weevil (Ceratapion basicorne) in the United States to help control yellow starthistle, an invasive weed found in 40 of the lower 48 states. The weevils will initially be released in California. Brad Hanson, weed specialist in Plant Sciences, addresses management of yellow starthistle.
