“Halting the Invasion in the Chesapeake Bay: Preventing Aquatic Invasive Species Introduction through Regional Cooperation,” a report by attorney Read D. Porter, examines coordination on aquatic invasive species (AIS) prevention among the Chesapeake Bay states. The report focuses on prevention-related legal authorities in Virginia, Maryland, and Pennsylvania in particular, and recommends actions to improve regional cooperation both within the existing regulatory frameworks and through potential amendments to state laws and regulations to enhance prevention.
“Gaps and inconsistencies among state laws can hinder AIS prevention,” says Porter. “Improving regional cooperation among Bay states and regional entities will provide for more effective and cost-efficient use of limited staff time and funding for AIS prevention.”
The report examines the primary pathways leading to the introduction of invasive species in the Chesapeake Bay and describes regulatory mechanisms used by Bay state agencies to combat AIS introduction. Based on this analysis, Porter concludes that coordinated AIS prevention in the Chesapeake Bay could be improved though both the amendment of certain existing AIS prevention laws and regulations and the enhancement of interagency coordination on a regional level. He recommends that Bay states and regional bodies:
- Require the Chesapeake Bay Program to respond to recommendations made by the Mid-Atlantic Panel on Aquatic Invasive Species
- Engage the Chesapeake Bay Commission and interstate river basin commissions in harmonizing state AIS policies
- Establish an interstate invasive species council workgroup
- Integrate all headwater states and agencies into regional AIS prevention bodies
- Harmonize and strengthen state AIS lists, as well as the importation, release, and escape protections that apply to listed species
- Develop new legal authorities to address ballast water, recreational vessels, and other emerging invasion vectors and strengthen regulation of horticulture and water gardening
- Fund existing AIS plans and develop a single AIS prevention plan for the Chesapeake Bay watershed that includes benchmarks for success.
