A.41. SUMMARY OF AQUATIC INVASIVE SPECIES MANAGEMENT IN 
SOUTH CAROLINA 
A.41.1. AQUATIC INVASIVE SPECIES MANAGEMENT PLANS 
No plan available. 
A.41.2. AQUATIC INVASIVE SPECIES PROGRAMS AND ACTIVITIES 
• Aquatic Nuisance Species Program, South Carolina Department of Natural 
Resources (SCDNR), the South Carolina Aquatic Plant Management Council. 
SCDNR, in coordination with the Council, develops and implements an annual 
management plan for the state, which includes identification of problem areas, a 
management strategy for the problem areas, and a budget. Management strategies 
include chemical controls, environmental controls (e.g., water draw-down in lakes, 
nutrient loading), surveys for invasive species, biocontrols, and mechanical harvesting. 
The annual management plan is submitted for a 30-day public review period in which all 
comments received are addressed and modifications are made to the plan. 
• Analytical and Biological Services, Santee Cooper (South Carolina Public Service 
Authority, a quasi-public entity). Santee Cooper actively surveys for aquatic invasive 
plants on Lakes Marion and Moultrie. All control operations are approved by and 
coordinated through the state Aquatic Plant Management Plan. The Water Quality 
Monitoring Program tests the water for invasive species two or three times a week and 
conducts aerial aquatic plant surveys of the lake system annually. Control efforts for 
hydrilla include the stocking of sterile grass carp. For water hyacinth, herbicides are 
sprayed from a helicopter or airboats as needed. For alligatorweed and water primrose, 
spot chemical treatments are applied as needed. 
A.41.3. CLIMATE CHANGE CONCERNS REPORTED BY STATE PERSONNEL 
• Some plant species that are sensitive to cold weather, such as water hyacinth and water 
lettuce, have started to move north and inland.
