You have completed Submodule 3.

Complete the interactive exercises for Submodule 3 to see how much you have learned.

Exercises open in a separate window.

Summary: Major Points from Submodule 3

  • The economic impacts of invasive rangeland weeds can be immense and far-reaching, but are largely undocumented. These impacts can be difficult to assess however, studies are underway to try and determine monetary costs.

  • Ecological impacts may be better understood, but much work still needs to be completed to understand these effects.

  • Both economic and ecological impacts can vary greatly for specific invasive plants. Information on some selected western weeds is presented.

 

When you are ready, proceed to Submodule 4.
