Saltcedar

Biological Control Agents

With extensive infestations of this weed on our major drainages Fremont County has been very involved in the effort to get bio-agents for saltcedar.

The Saltcedar leaf beetle, Diorhabda elongata was released at two research sites in the Boysen reservoir area during the summer of 2005. We are expecting that this defoliating agent will be successful getting established and spreading as it has in other areas of the mountain west. Within the next few years we hope to be able to collect and redistribute Diorhabda in Fremont County.
