    Description

    Seed shatter dates for antelope bitterbrush were estimated from collections at 192 sites in Oregon and surrounding states. Shatter date was strongly correlated to elevation, and an equation that included elevation, latitude, longitude, and longitude squared explained 79 percent of the variation in seed shatter dates. This information can assist those needing to schedule seed collection activities at multiple locations.
