A.9. SUMMARY OF AQUATIC INVASIVE SPECIES MANAGEMENT IN DELAWARE 
A.9.1. AQUATIC INVASIVE SPECIES MANAGEMENT PLAN 
No plan available. 
A.9.2. AQUATIC INVASIVE SPECIES PROGRAMS AND ACTIVITIES 
• Survey and inventory of aquatic vegetation in Delaware ponds, Department of 
Natural Resources and Environmental Control (DNREC), Division of Fish and 
Wildlife. This program has two components: (1) control of aquatic nuisance species in 
public ponds, and (2) survey and mapping of aquatic vegetation in public ponds (invasive 
and rare species). Species surveyed and mapped range from open water species to the 
emergent shoreline vegetation. The department uses the maps to calculate the acreage 
figures, which can be used to document the species changes over time. 
• Delaware Landowner Incentive Program (DELIP), DNREC Division of Fish and 
Wildlife. DELIP provides grant assistance to private landowners for habitat restoration, 
including invasive species control projects. 
• Phragmites Control Program, DNREC Division of Fish and Wildlife. The program 
uses helicopter application of herbicides to control Phragmites in state wildlife areas and 
private lands (cost-share arrangement between landowners and the state). 
• Technical assistance to pond owners, DNREC Division of Fish and Wildlife. The 
division provides assistance with invasive weed control, including recommendations on 
herbicides, manual control, or biocontrol, and dissemination of best management 
practices such as riparian buffer strips and nutrient control. 
• Delaware Invasive Species Tracking System, Delaware Natural Heritage Program, 
Delaware Invasive Species Council, U.S. Geological Survey, Leetown Science 
Center. The system is a prototype for invasive species reporting and tracking. The goal 
is to develop an online tool for mapping and cataloging locations of invasive species in 
the state. 
• Wildlife Habitat Incentives Program, U.S. Department of Agriculture (USDA) 
Natural Resources Conservation Service, DNREC. This is a cost-share program for 
private landowners who control Phragmites on their property. The DNREC provides a 
share of the cost (30%) and conducts the spraying. The USDA and the landowner also 
provide shares of the cost (58% and 12%), respectively. 
• Delaware River Invasive Plant Partnership, States of Delaware, New Jersey, New 
York, and Pennsylvania.
