A.39. SUMMARY OF AQUATIC INVASIVE SPECIES MANAGEMENT IN 
PENNSYLVANIA 
A.39.1. AQUATIC INVASIVE SPECIES MANAGEMENT PLAN 
Pennsylvania’s Aquatic Invasive Species (AIS) Management Plan was published in 
October 2006 (see Appendix B, State Aquatic Invasive Species Management Plan Summaries for 
a general description of the Plan). 
A.39.2. AQUATIC INVASIVE SPECIES PROGRAMS AND ACTIVITIES 
• Stream ReLeaf Program, Pennsylvania Department of Environmental Protection 
(PA DEP). PA DEP holds riparian plant identification classes for staff from regional 
offices, county conservation districts, and watershed groups. The classes cover the 
importance of riparian buffers and restoration projects, as well as biodiversity and native 
and invasive plants. 
• Delaware River Invasive Plant Partnership, States of Delaware, New Jersey, New 
York, and Pennsylvania. 
• Zebra Mussel Control, private water suppliers. The water suppliers apply chemicals, 
like chlorine, to intake screens on public water supplies to control zebra mussels. 
• Pennsylvania Sea Grant. Sea Grant has conducted Hazard Analysis and Critical 
Control Point training for state and federal agencies and developed outreach materials on 
specific AIS, including materials for AIS prevention among boaters. 
• Zebra Mussel Monitoring, PA DEP. PA DEP is tracking the distribution and spread of 
zebra mussels in the Great Lakes region. The agency originally set up -170 monitoring 
stations across the state and alerts contacts for adjacent water bodies when there is a new 
discovery. 
• Invasive plant species control, Pennsylvania Department of Conservation and 
Natural Resources (PA DCNR). PA DCNR controls invasive plant species on the lands 
and in the associated waters that it manages with systemic herbicides and mechanical and 
biocontrols. 
• Pennsylvania Invasive Species Council. The Council, established by executive order in 
2004, advises the Governor on invasive species issues in Pennsylvania. The council is 
also charged with (1) Developing and implementing a comprehensive invasive species 
management plan for the state; (2) Providing guidance on the prevention and control of 
nonnative invasive species and rapid response to new infestations; and (3) Facilitating 
coordination among federal, regional, state, and local initiatives and organizations 
engaged in the management of nonnative invasive species. The Council is comprised of 
seven state agencies and 10 at-large members.
