invasive plant research

Invasive species are considered second only to habitat destruction in causing species extinctions. Ecosystems of the Rocky Mountain Region are threatened by many invasive plants, including Tamarix (tamarisk, saltcedar), Russian olive (Elaeagnus angustifolia), and cheatgrass (Bromus tectorum). We conduct research on the impacts of invasive species, their control, and restoration after removal. Our current emphasis is on invasion of riparian (riverbank) zones.

Invasive Weed Information

Rare weeds of Colorado Identification Project: Download or request a printed copy of our beautiful “Rare Weeds of Colorado” poster and learn about the “List A” species and how you can help prevent their spread.
Colorado State Extension Service Weed information: Information on the state’s most common weeds.
Colorado Department of Agriculture Weed list: Contains an updated list of Colorado weeds and state status.

Research

Through Dr. Anna Sher’s joint position with the University of Denver Department of Biology, graduate students are studying impacts of invasive species on native ecosystems. Read about how Dr. Sher is protecting Colorado's ecosystem on the University of Denver Web site.

Restoration

We conduct research on restoration approaches, including the use of mycorrhizas for native plant revegetation, and integrated pest management of invasive weeds. Past projects have included investigations of the use of fire to control cheatgrass (Bromus tectorum), and use of mechanical and chemical means to remove Tamarix spp. (tamarisk, saltcedar).

Currently, in collaboration with the Department of Interior and the EPA, we are producing best management policies manuals on methodology to control tamarisk and conduct revegetation after tamarisk removal. Contact our scientists if you are interested in this project, or would like to receive a copy of the manual when it is available.
