A.7.1. AQUATIC INVASIVE SPECIES MANAGEMENT PLAN 
No plan available. 
A.7.2. AQUATIC INVASIVE SPECIES PROGRAMS AND ACTIVITIES 
• Aquatic Plants Management Program, Colorado Department of Agriculture 
(CODA). The program operates several projects throughout the state. Work includes 
both manual removal and chemical treatments. Presently, the focus is on the Rio Grande 
Watershed, the upper part of the Colorado River, the North Platte River, the San Miguel 
River, and the Republican River watershed. (The main coordinator for the San Miguel 
Project is The Nature Conservancy.) There are also control efforts under way for 
Siberian Elm, including mechanical removal, herbicide application, and cut stump 
treatment. There are plans to implement biocontrol for tamarisk as well. 
• Biocontrol of Tamarisk, CODA. The Department’s Insectary in Palisade, Colorado is 
the clearinghouse for the project. Officials are working in collaboration with U.S. 
Department of Agriculture and Colorado State University to release beetles in Colorado, 
Wyoming, South Dakota, Montana, Oregon, Kansas, and Idaho to control tamarisk. 
About 60,000 tamarisk leaf beetles have been released in seven states with additional 
releases planned. In August 2005, beetles were released at three Colorado sites: Adams, 
Mesa, and Yuma Counties. In 2006, beetles were released at Dinosaur National 
Monument in Moffat County and several additional sites in Colorado and the West. 
• Aquatic Animal Management Program, Department of Natural Resources, Division 
of Wildlife (CODW). Major activities of CODW on aquatic invasive species (AIS) 
include: (1) angler education; (2) hatchery maintenance; (3) activities to detect location 
of New Zealand mud snails (NZMS); and (4) participation in the Western Regional Panel 
of the Aquatic Nuisance Species (ANS) Task Force. Colorado State Parks is cooperating 
with CODW by providing them with GIS/GPS training, ANS mapping access/support, 
and collaborating on various education projects, control methods, and statewide planning 
efforts. 
• Eurasian Watermilfoil (EWM) activities, Colorado State Parks. The Stewardship 
Section of Colorado State Parks is the central coordinator and GIS clearinghouse for 
EWM efforts in Colorado. The program is actively working towards several short- and 
long-term objectives that include coordination, mapping, data collection, grant writing, 
planning, early detection and rapid response, partnering with local universities on 
research, education campaigns, convening stakeholders, studying economic impacts, and 
implementation of boat washing stations.
