A.28.3. CLIMATE CHANGE CONCERNS 
• Increased drought caused by changes in climate may cause purple loosestrife and 
Phragmites populations to increase drastically. 
• Warmer temperatures may affect some species, but not others. 
A.28.4. CLIMATE CHANGE ACTIONS 
(None reported.) 
A.28.5. RESEARCH ACTIVITIES AND INFORMATION USED 
• Nebraska is developing a strategy to eliminate or reduce purple loosestrife through the 
use of mechanical (digging), chemical (herbicides), or biological (insect) controls. 
• Chemical experiments are being conducted on Phragmites by spraying habitat via 
helicopter over 80 acres along the river. Grazing cows and goats are also being used as a 
trial method to control Phragmites. 
A.28.6. RESEARCH NEEDS 
• Information about Asian carp is needed. 
• Identification of native and non-native species is needed. 
• New techniques for more effective or selective control and herbicides need to be 
developed. 
• An understanding of where purple loosestrife seeds will be disseminated and where it 
may reappear is needed. 
• More knowledge about the anatomy and botany of invasive plants is needed.
