This manual contains three types of activities. First there are introductory, or awareness-building, activities. The second type focuses on both beneficial and detrimental characteristics of exotics. And finally there are activities intended as reinforcers. The best advantage can be gained from this set by selecting at least one introductory activity and several from the second set and following up with routine monitoring of a nonindigenous species in your community.
