Introduction

Controlling alien weed species is a significant undertaking in terms of labor and cost. Alien weed species will continue to spread as long as they can survive in an environment. Altering the conditions that favored the invasion must become part of the solution. Students will become familiar with the process of experimental design as they explore and invent innovative solutions to controlling invasive weed species.
