Purpose of the Experiment
BU Beach
Map of BU’s Charles River Campus
Observations Human Interaction: ● ● ● ●
Pedestrian Traffic Manmade structures Hang-out place Highway
Observations Natural elements: ● 35% trees ● Scattered sunlight ● Wildlife
Observations tells us: The BU Beach is a dual-element biota.
Trees of the BU Beach 8 different species of trees!
Leaves of the BU Beach Pt. I
Shumard Red Oak
Red Oak
Fringe Tree
Sycamore Maple
Leaves of the BU Beach Pt. II
Empress Tree
Spanish Oak
Higan Cherry
Table-mountain Pine
Density of trees •35% Trees –Shumard Red Oak(1) –Higan Cherry(5) -Fringe Tree (1) -Spanish Oak (5) -Table-Mountain Pine(2) -Red Oak (2) -Sycamore Maple (1) -American Linden (2) -Allegheny serviceberry (1)
Height of Trees •Tree Heights: –Shumard Red Oak (19.50) –Higan Cherry (12.14) –Table-Mountain Pine (14.50)
Histograms
Physical Properties of Soil at the BU Beach - Soil Texture: mostly clay - Collected & tested Litter Layer (O) and Topsoil (A)
Chemical analyses- Soil and water Soil

Ph: 7
Ph: 8.9
P: N/a N: N/a
P: N/a N: N/a K: 3
K: Very high -Same properties as Boston tap water
Calculating Diversity of the BU Beach Shannon-Wiener Diversity Index log N = log(18) = 1.26 H’= 3.322 x 1.26-(7.714/18) H’= 3.222 x (1.26-0.429) H’= 2.68 0 = stressed, 4 = stable Conclusion: BU Beach is slightly more stable than stressed.
The Esplanade
Observations -Close to the water -Popular among runners, walkers, and bikers. -Vegetation -Heavy pedestrian traffic
Density and Heights of Trees •25% Trees –Hedge Maple (6) –Shingle Oak (4) •Tree Heights: –Hedge Maple (~21m) –Shingle Oak (~18m)
Physical Properties of Soil and Water at the Esplanade -Esplanade sample 1: 5% organic content; categorized as clay soil; 85% minerals, 5% water, 5% air.

Calculating Diversity of the Esplanade Shannon-Wiener Diversity Index: log N = log 10 = 1 H’= 3.322 x 1 - (7.08/10) H’= 3.222 x (1-0.708) H’= 0.940824 0 = stressed, 4 = stable Conclusions: the Esplanade is very stressed.

SIMILARITIES -
Abundance percentages are close Soil Chemistry Human Interaction
Diversity of trees Environmental Surroundings
So Why are any of these results particularly interesting? BECAUSE: Everything makes a difference!
Summary and Conclusions We did:
