This Black Locust Tree is found across Prospect Street from Sterling Chemistry Laboratory, and just up the hill from Ingalls Ice Rink. If you were a squirrel that lived in this tree, you would be able to see students walking to their laboratory classes in the morning and fans coming to cheer for the Yale hockey team in the evening. At lunchtime, you might even be able to smell the delicious scents of Thai and Mexican food from the food trucks by the intersection of Sachem and Prospect. At almost 70 feet tall, this particular Black Locust tree would give you an excellent bird's-eye view of campus. Despite its size, the Black Locust is actually a member of the pea family, Fabaceae. Black Locust trees produce fragrant flowers and pea pod-shaped fruits. While they are flexible with regards to soil type, and can grow in a variety of locations, Black Locust trees do require plentiful sunlight and open ground. Black Locust trees can be found throughout all of the United States except Alaska and Hawaii, as well as parts of Canada, Asia, Europe, and southern Africa. However, their normal range is limited to the southeastern United States. Black Locusts are valued for the honey produced from their flowers as well as its durable wood. However, this tree can become invasive due to its ability to produce large quantities of seeds and reproduce via root suckers.

This massive red oak is located in the center of science hill, near the Yale Science building and in front of Kline tower. Measuring over 70 feet tall and with a canopy area of over 400 square meters, this tree provides shade and a beautiful view to all who pass by it. Like all red oak, it has fissured and sturdy gray-brown bark and numerous branches, some which dangle dangerously close to the footpath.
