Interpretive Summary: Western juniper has expanded into millions of acres of rangeland during the past 100 years. In many cases the expansion of juniper has resulted in decreased forage production and biodiversity, and increased soil erosion. There are currently many juniper control projects aimed at restoring sites that have been invaded by juniper. Weed invasion after juniper control is a major concern. Past research has shown that some types of weed invasio are short-term and do not keep a site from recovering to the condition that existed prior to juniper invasion. However, results are site specific and there are a series of steps that managers can use to help guide decisions about juniper control and subsequent weed management.
