establishment. Within 24 hours of a call, the Task Force assesses the site and arranges 
for control treatments if salvinia is found. 
• North Carolina State University Aquatic Weed Management Program. This 
program conducts research and outreach activities related to invasive plant management 
on aquatic and non-cropland sites. Activities include the following: Evaluation of 
chemical, biological, physical, mechanical, and other methods of controlling invasive 
plants; Determination of biological and ecological characteristics of invasive plants that 
contribute to spread, establishment, and management; Dissemination of current 
information to managers, government employees, and others related to management of 
invasive plants; and Interaction with government agencies and private entities to improve 
management of invasive plants. 
A.34.3. CLIMATE CHANGE CONCERNS REPORTED BY STATE PERSONNEL 
• Biocontrol is being used for alligatorweed works better in warmer winters. 
• Water hyacinth is a problem only in the southeast comer of the state, but this is also the 
warmest region. 
• Air and water temperature monitoring at some sites shows that giant salvinia is surviving 
at much colder temperatures than the literature reports. 
A.34.4. CLIMATE CHANGE ACTIONS 
(None reported.) 
A.34.5. RESEARCH ACTIVITIES AND INFORMATION USED 
(None reported.) 
A.34.6. RESEARCH NEEDS 
• More infomiation on the best way to control hydrilla is needed (herbicides vs. grass 
carp). 
• More information needs to be collected on the biology and ecology of invasive species 
(i.e., seed longevity) that would help improve control methods.
