Step 1: Download software and data • http://serc.carleton.edu/eet/forest/part_1.ht ml • Download Myworld GIS • Download other files on this website Step 2 • Lets look at Auburn Land Lab Data (orange) • It is not diverse • Red Oak + Red Maple = 68% Species Distribution Auburn American White Oak Beech White Pine 2% 8% 4% White Ash 2% Sugar Maple 4% Red Oak 34% Black Oak 2% Balsam Fir 2% Other Oak 4% Paper Birch 4% Red Maple 34% Look at Larger Area (green) 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
