A.9.3. CLIMATE CHANGE CONCERNS 
(None reported.) 
A.9.4. CLIMATE CHANGE ACTIONS 
• DNREC surveys and maps species ranging from open water to emergent shoreline 
vegetation. The department uses these maps to calculate the acreage figures, which can 
be used to document species changes over time. 
A.9.5. RESEARCH ACTIVITIES AND INFORMATION USED 
• The Delaware Invasive Species Tracking System is being developed as an online tool for 
mapping and cataloging locations of invasive species within the State of Delaware. 
• The DNREC conducts surveying and mapping of aquatic vegetation in the ponds to 
determine invasive and rare species. 
A.9.6. RESEARCH NEEDS 
• Maps of areas with high populations of invasive species are needed. 
• A watershed approach needs to be taken when working with landowners in order to better 
prevent invasive species spread. 
• A database of effective control methods for invasive species is needed.
