Getting Started

About The Learning Modules

The Volunteers and Invasive Plants—Learning and Lending a Hand learning modules are provided by the U.S. Fish and Wildlife Service’s National Wildlife Refuge System for the volunteers who generously devote their time and effort to invasive plants problems. The goals of the learning modules are to enrich the volunteers’ experiences and to provide them with more knowledge of invasive plants. The more knowledge that one has, the more effective one can be in making a difference within a refuge and beyond its boundaries.

Tips For Using The Learning Modules


To get the most out of the learning modules consider the following:

  • Glance over the modules to get a feel for the topics and information that may spark your interest.
  • Set aside time to read a module completely. Leave time to take the "Test Your Knowledge" quizzes afterwards.
  • Explore the materials and websites that are linked from the modules.
  • In the computer’s browser, bookmark pages that are of interest.
  • If you prefer reading printed materials print the modules and add them to a 3-ring binder. Add other information to the binder to build upon the topic.
  • Use the modules as a reference—return to them for information.


  • After opening a PDF, slide show, or visiting website linked from a module, use the "back" button on the browser window to return back to the module. If you close the browser window by clicking on the X button in upper right corner instead of using the "back" button, the Volunteers and Invasive Plants website will close.
