Halting the Invasion: State Tools for Invasive Species Management

In August 2002, the Environmental Law Institute released it’s report, Halting the Invasion: State Tools for Invasive Species Management. The report analyzes the legal tools available at the state level to combat invasive species. Only those laws and policies approved through state legislation or agency rulemaking were addressed. The report highlights 17 invasive species tools found in state statutes and regulations. These tools are divided into five main categories: prevention, regulation, control and management, enforcement and implementation, and coordination. The report recommends that states evaluate which of three standards (gold, silver, or bronze) their invasive species laws and regulations currently meet.

The appendix presents the state-specific data that was collected and analyzed for the report. The information contained in this appendix was obtained primarily through research on state statutes and regulations conducted from February 2001 through February 2002. For each state, the statutes and regulations affecting five general categories of invasive species were examined. These categories are invasive wildlife; invasive aquatic species; invasive plants; plant pests and diseases, including pathogens and microorganisms; and insects.
