The invasion by non-native saltcedar (Tamarix L. spp.) has caused enormous damage on native plant and animal communities, especially in riparian ecosystems in areas of the western United States. The main methods of control currently used, mechanical, chemical and manual, have proven to be enormously expensive. In the last few years, biological control using an introduced leaf-eating beetle, Diorhabda elongata, has shown a very high potential for success. Success stories of biological control include saltcedar stands along the Humboldt River in Lovelock, Nevada where this beetle defoliated about 5,000 acres of saltcedar. The Colorado Noxious Weed Act of 1996, the State Weed Law and two bills passed by the 108th Congress have enabled county, city and state governments to utilize and implement management programs to target saltcedar. The intent of this research was to monitor and examine the effects of the chemical and mechanical treatments of saltcedar in Fremont County, Colorado. The results of this research indicate that chemical control has had a significant impact on killing saltcedar from pre-treatment status to post-one-year and post-two-year status. It was found that the Hydroaxe control method cleared areas of stands of saltcedar but new growth appeared form below the cut stump of the plant. Protocol for herbicide control, according to the manufacturer's label, recommends that treated areas should be left undisturbed for approximately three years after application.
