As a class, discuss:
1.) Which student chose the neighborhood with the most trees? Check for understanding: Is it easy to directly compare neighborhoods regarding tree totals? What other information would we need to know to understand which neighborhoods are the most tree-dense?
2.) Which species were the most common in their respective neighborhoods? Why do we think that might be?
3.) Looking at Part Two, can we figure out which tree with a 12-inch trunk diameter gives us the most “value” (out of the ones we found, at least)? Check for understanding: Why did we control for size in this exercise?
4.) Were there any surprises?
5.) What information is needed to understand trees’ total cost value to New York? (Among other things, the cost of maintaining and planting needs to be factored in.)
6.) What other types of value does this economic analysis leave out? (Students should be able to identify intangible factors like making the city pleasant and aesthetically appealing.)
Optional extension: If the season permits, encourage students to look around them as they walk on the streets and see if they can identify some of the species (good ones to start with are the London Planetree, Thornless Honey Locust, and Ginkgo) they discussed today. Have them take pictures and share with the class.
