1 Seeing the Forest for the Trees An EET workshop

2 Key Point Taking too small of a data sample will distort scientific data Lots of data gives the big picture

3 Why Are Forests Important? Beauty Resource Help the Earth

4 What is biodiversity in a forest? No 2 trees add up to more than 50% Example: in the first study we’re going to look at, red oak and red maple add up to 68% This is not diverse.

5 Step 1: Download software and data http://serc.carleton.edu/eet/forest/part_1.ht mlhttp://serc.carleton.edu/eet/forest/part_1.ht ml Download Myworld GIS Download other files on this website

6 Step 2 Lets look at Auburn Land Lab Data (orange) It is not diverse Red Oak + Red Maple = 68%

7

8 Look at Larger Area (green)

9 Together they show diversity No 2 species make up more than 50% Each green dot by itself does not have diversity, but together they do
