Invasive Species Prevention Zones

By delineating ISPZs, land managers can prioritize conservation goals and maximize limited resources by focusing on areas that are relatively free of invasive plants, and that have high ecological value. The use of ISPZs as a tool by land manager will also help to focus public and private funding, planning and eradication efforts on these important areas. 

Resiliency is defined as the amount of change or disturbance that a system can absorb before it undergoes a fundamental shift to a different set of processes or structures. We all rely on the resiliency of the ecosystems within our ISPZs as they provide important ecosystem services to us such as filtering our drinking water, providing refuge for pollinators, and attenuating wave energy to protect us from extreme weather related damages. 

Disturbed ecosystems are less resilient and more susceptible to pests. If a management response has been made, it may be necessary to engage in restoration as deemed appropriate. Prevention and coordinated management efforts allow for long term monitoring and restoration that can aid in the success of a management response and ensure the resilience of our ISPZs.

ISPZs can be educational opportunities to not only prevent the introduction and spread of invasive species within the ISPZ, but also strengthen awareness of invasive species to community members who may live within the buffer zone of the ISPZ.

Signage and info sheets should be developed and made available at ISPZ access points along with tools such as boot brush stations to prevent the spread of invasive seeds. Community engagement and websites can be a valuable resource to educate the public on pathways of invasive species introduction. 

With more people aware of invasie species and their pathways, more of them can take precautions that help prevent introductions, as well provide them the tools to as act as early reporters within these large areas of ecological importance.
