Directions You will be show a series of pictures of plants and animals. Some of them have evolved in this area and are living within their normal range. They are called native or indigenous. Some of them are from not from here and are living outside their normal range. They are called introduced or exotic. Some of them do not upset the balance of ecosystems and are harmless or sometimes beneficial. Some of them upset the balance of ecosystems and are harmful or invasive. The following chart organizes the four possibilities. Make a quick 3 by 3 chart in your note book leaving space for answers.

Not invasive or Does No Harm to Ecosystems Invasive – causes damage to ecosystems With in its normal range Indigenous/Native Quadrant 1 Eg. Douglas Fir Quadrant 2 Eg. Western Pine Beetle Not Within its normal range Introduced/Alien/ Exotic Quadrant 3 Eg. Carrots Quadrant 4 Eg. Yellow Perch

When you see the picture, decide if the animal or plant would fit into quadrant 1,2,3,or 4. Hold up fingers to indicate the quadrant. Hold up 1 finger for quadrant 1, 2 fingers for quadrant 2 etc. See which answer is suggested and discuss if you disagree. Answers may vary according to where you live and according to personal point of view. Be sure to be able to back up your answer with examples. Quickly jot down the name in the quadrant it belongs. Look for patterns and try to think of your own examples.

Write it in your note book. The following slide gives an example of a generalized statement from the Ministry of Environment.
