TREES GONE WILD

Purpose

• Development of the Brighton Campus at Boston College as an economic benefit or detriment to the community

• Planting or removing trees to access effects on air pollution removal, carbon storage and sequestration, and residential cooling

Data Collection Tools

Tree Height and Diameter

• Tree height was measured using a Clineometer.

• Tree Diameter was calculated using tape measures to measure circumference and then dividing by 3.14

Data Collected

• In the field we collected data such as:Type of trees, size, and locationHealth and growing conditions of treesNumber of Air Conditioners per house

• Using Arc View we programmed in data for the trees, buildings, AC units, paved areas, water areas, and grass areas over a satellite picture of our study site.

• To test the question, we ran a data set with an increased amount of younger trees added to the study area.

After Simulation with Arc View

Entering Data in the Field

•Trees were identified using an interactive dichotomous key.

•Tree data was then entered into Arc View using the City Green charts

What would happen if the Brighton Campus of BC was developed with dorms and parking and the trees presently occupying the space were cut down?

Four Research Questions

What would happen if the Brighton Campus of BC was developed with dorms and parking areas but new young trees were added?

What would be the effect in 25 years after the trees have matured?

What would happen if trees were added in another area close to the Brighton campus and the Brighton campus remained undeveloped?

What would happen if the Brighton Campus of BC was

developed with dorms, fields, parking and the trees presently occupying the

space were cut down?

Conclusion: Why trees must be added to the BC Brighton Campus when Developed

• Saves $$– Reducing energy costs shade – Helps store storm water.– It also helps the earth from heating up due to all

of the carbon absorbed

Research Question

What would happen if trees were added in another area close to the Brighton campus and the Brighton campus remained undeveloped?

CONCLUSION

• Increase the Shade which will lower the temperature

• A lower temperature causes reduce of energy use by the condos

• Economic Benefits • Increase air pollution removal• Increase carbon storage and sequestration
