GRAND RAPIDS (WZZM) - After one year of surveying, Calvin College biology and geography students have created an inventory and map of every tree on campus, west of the Beltline. The project began in the fall of 2010 under the direction of Calvin College biology professor Dave Warners and geography professor Jason VanHorn.

"As we start thinking about a more sustainable campus and trying to become carbon neutral, it seemed to make sense that we needed to document the trees on campus," Warners said. "In order to know how much carbon sequestration we have on campus, we have to know the number and size of trees.

The online tree map contains details of the size, species, location and age of more than 3,500 trees.

Among the summary statistics was the total number of trees (3,516), the number of species (112), the number of landscaped vs. natural trees (1138/2378) and the number of each type of tree: Norway Spruce is the most common at 305. There are 194 Red Oak trees and 157 Sugar Maples. The Kentucky Coffee Tree is the most unique, according to Warners; there are three of these on campus.
