The product:


  1. A “Wanted” poster for EACH of your species. Must be “poster” size (22x28) and you can divide the poster into four to contain the four species you selected. Make some form of dividing line to separate your four wanted posters. On your poster you must include:

NAME / ALSO KNOWN AS (latin name / common name / “criminal” name)

PICTURE – a drawing or photograph (color would be nice)

IDENTIFYING CHARACTERISTICS – key features to look for when identifying the criminal

LAST SEEN – where did the species originally come from? include a map.

SUSPECTED HIDEOUTS - include a map of the U.S. with its current distribution shaded; description of preferred habitat

CRIMES COMMITTED by your species (crimes must be specific to your species and not general to all invasive species)

REWARD for elimination of your species (think ecologically, economically, socially, politically – again, be specific for your species)

Color, neatness, and creativity


  1. Bibliography -- list of internet sites /web addresses OR appropriate bibliographic information


  1. Presentation - you will share the information on your species with the class in a brief oral presentation (2-3 minutes). When planning your presentation, keep in mind all of the concepts we have studied in this unit that relate to the topic and try to tie them in. In other words, think "third tier" learning.


The presentation component will be graded on the following:

explanation of all the information on your poster in more detail than poster allows

introduction history (where it came from and how it got here)

  • methods of control

Species profile page of


Biodiversity and Conservation: A Hypertext Book by Peter J. Bryant


Research: Obtain more information on your species by doing a web search. Be sure to document your sources. (title and address of all web pages used – put these on back of your poster)
