A.Prepare and graph your data. (4 points)

  1. Calculate totals for each riparian category (sum your columns)

  2. Calculate category percentages by dividing each category total by 2000 and multiplying by 100

    1. (Category total / 2000) * 100

    2. Organize percentages for ALL categories on a spreadsheet and PASTE below

  1. Graph your category percentages using a cluster column graph in excel and paste below (be sure to include a title, axes labels, and units)

B.Interpret your graph (3 points)

1.Do riparian zones differ between developed and natural areas oncampus? If so, how?

Yes.They differ because natural area has more percentage of bare ground,leaf litter, deadfall, shrub, and conifer than developed area whiledeveloped area has more of impervious cover, grass, and deciduousthan natural area.

Overall,the natural area is concentrated with leaf litter while developedarea grass takes the largest share of the cover.

C.Infer riparian zonefunction (3 points)

1.How, specifically, does riparian zone functiondiffer between developed and natural areas on campus?

Thedeveloped area targets retention of more water and preventingevaporation whilenatural area exposes the ground therebyincreasing evaporation (Haarder,Looms, Jensen &amp Nielsen, 2011)

Thedeveloped areas allow higher percolation of water to the groundcompared to natural areas (Heibaum,2014).

Naturalarea allows surface runoff to sweep soil (Kendall,Axelso, &amp Yost, 2012), whilethe developed area slow the runoff and act as sieve that preventssweeping of surface materials to the river (Shah,Yusof, Mustaffa &amp Hashim, 2013).
