Invasive Species Prevention Zone Creation

How ISPZs are created:

1. High-priority natural areas that are likely to be relatively free of invasives are identified and delineated


2. Invasives are mapped within and around the area


3. A site-specific, integrated pest management plan is created that focuses on Prevention and EDRR strategies

The ISPZ Plan

Once an ISPZ has been delineated and mapping has been completed, a site-specific management plan should be created and implemented. This management plan should include strategies to:

• Identify and interrupt invasive species pathways


• Manage land/water to enhance growth of desired natives


• Implement early detection/rapid response strategies
• Educate staff, visitors and volunteers and neighbors
• Update invasive species location maps
• Immediately control


• Monitor
• By means of the ISPZ criteria
• Results of control efforts
