CLIMATE CHANGE CONCERNS 
• Species that currently cannot overwinter in Colorado, such as giant salivinia or water 
hyacinth, may persist if climate changes occur and water temperatures increase. This 
depends both on whether the water is hot or spring fed and on the location of the species 
within the state. 
A.7.4. CLIMATE CHANGE ACTIONS 
• Angler education program focuses on prevention through outreach, including posting 
angler alert signs at trout fishing locations and live fishing tackle stores. 
• Hatchery maintenance program ensures that fish production units remain free of invasive 
species. 
A.7.5. RESEARCH ACTIVITIES AND INFORMATION USED 
• Colorado is involved with the tamarisk biocontrol program. One of the first field sites 
used to test biocontrol beetles in North America was located near Pueblo, Colorado. The 
CODA Insectary has been involved in the project for several years and has received a 
permit to store up to 1 million beetles for use in biocontrol in 2005. 
• Weed researchers in the state are studying AIS and the use of biocontrol. These 
researchers are collaborating with federal agencies such as U.S. Geological Survey. 
• Records on the location of newly discovered species are being maintained.
