A.35.5. RESEARCH ACTIVITIES AND INFORMATION USED 
(None reported.) 
A.35.6. RESEARCH NEEDS 
• The length of seed viability of salt cedar at northern latitudes and climates needs to be 
researched. This information would be invaluable in making salt cedar management 
plans. Field observations by weed managers show that seed is viable much longer in our 
colder climates than where prior seed viability research was conducted. 
• Research on the mechanism of spread of salt cedar is needed. Anecdotal evidence points 
towards waterfowl and wind as being primary means of salt cedar spread. This research 
data would assist weed managers in concentrating their survey efforts and resources in 
those areas most likely to be infested. 
• Research should be conducted on ability of ANS to be transported to North Dakota and 
the likelihood that they will become established in state waters. The study should include 
a risk assessment based on pathways information, frequency of movement into the state, 
and suitable habitat availability.
