The Napa Vineyard Workforce, 2000-2015

We recently completed a survey of Napa vineyard employee gender diversity between 2000 and 2015 in five job categories. Our findings suggest that there has been a recent and rapid change in gender diversity, particularly in seasonal labor crews. 

Other industries have devoted considerable resources to understanding team dynamics--with the goal of optimizing performance to the benefit of both economic efficiency and worker satisfaction. However, research in agricultural settings is largely non-existent, something which we aim to rectify.

Monitoring Guide for Western Grapeleaf Skeletonizer

On June 24, 2015, staff of the Napa County Agricultural Commissioner found one male Western Grapeleaf Skeletonizer in a pheromone-baited trap in a vineyard on Tubbs Lane in Calistoga. 

UCCE Advisors Lucia Varela and Monica Cooper developed a "Monitoring Guide for Western Grapeleaf Skeletonizer" so that vineyard owners, growers and workers could familiarize themselves with the pest's life stages and feeding habits.
