Document Description
Northern tamarisk leaf beetles (Diorhabda carinulata) will be released on invasive exotic tamarisk trees (Tamarix ramossissima) that are reducing the quality of wildlife habitat at the wildlife area. The beetles exclusively feed and reproduce on tamarisk. Tamarisk initially re-grows after defoliation, but gradually dies back. This will allow native riparian plants like willows and cottonwoods to re-colonize the ecosystem.
