A.13.3. CLIMATE CHANGE CONCERNS 
• In conducting the initial assessment for the Aquatic Invasive Species (AIS) Action Plan, 
officials considered latitude, longitude, temperature bands, elevation, and rainfall. 
A.13.4. CLIMATE CHANGE ACTIONS 
(None reported.) 
A.13.5. RESEARCH ACTIVITIES AND INFORMATION USED 
• Idaho is carrying out genetic analysis of Myriophyllum species and potential hybrids 
within the state. 
• Physical surveys and mapping are being conducted 
• Surveys of the Northern Idaho Lake are being done to determine the densest areas of 
EWM. These areas are then targeted with appropriate control methods. The less-dense 
areas are targeted by divers using hand-pulling techniques (removal of plants by the roots 
followed by vacuuming). 
A.13.6. RESEARCH NEEDS 
• Information on biocontrol methods is needed. This may require visits to the country of 
origin to examine the species under consideration. 
• Reliable and continual funding is needed. 
• Effective controls based on population size and the presence of other species are needed. 
• Information on both the economic and ecosystem-related effects of specific AIS is 
needed. 
• An effective herbicide, with less environmental impact, that can be applied in smaller 
amounts is needed. Researchers are currently looking for this type of herbicide. 
• Bottom barriers are needed. Researchers are assessing the duration of placement for 
effective control and the potential for growth of aquatic plants after sediments have 
settled on the barriers. 
• A soil-mix company that will recycle the milfoil into a soil mix is needed. 
• Better ways need to be identified for more state partners to educate the public about why 
it is important to control EWM. A national or statewide database that could provide up- 
to-date information on current research being done for each invasive species would also 
be helpful.
