Abstract
The objective of this study was first to understand how ENSO seasonal change interacts with grass production and cow-calf production in north central Florida, and second, what management decisions ranchers could make to reduce risk and vulnerability, thus taking advantage of improved forecasts. For this study, 38 ranchers and 41 extension agents were interviewed.
