A.46.4. CLIMATE CHANGE ACTIONS 
(None reported.) 
A.46.5. RESEARCH ACTIVITIES AND INFORMATION USED 
• Research continues to provide new non-chemical control methods to reduce reliance on 
lampricides. 
A.46.6. RESEARCH NEEDS 
• The current distribution of specific ANS and the impacts they have on ecosystems and 
native species needs to be researched. 
• The economic impacts of ANS need to be determined. 
• The reason Phragmites have appeared where beetles have reduced the presence of purple 
loosestrife needs to be identified. 
• The impacts of ANS in other states and effectiveness of control programs needs to be 
researched. 
• Monitoring needs to take place for new ANS. 
• Sea lamprey control technology needs to be developed. 
• The effectiveness of filtering to control plankton populations and of using pheromones to 
lure lampreys needs to be evaluated. 
• The densities of zebra mussels throughout their life stages need to be monitored.
