(WBIR-University of Tennessee) If you see tree climbers scaling trees that are up 100 feet tall off Neyland Drive -- don't be alarmed.

"Never thought that would be going on," UT senior Spencer Wyatt said before climbing up an 80 foot tree on campus. He's one of the 20 students taking part in an urban forest class in the Department of Forestry, Wildlife and Fisheries.

"We learned all about managing forestry in the urban setting." he added.

Dr. Sharon Jean-Philippe currently teaches the students how to properly climb trees, with every knot, rope, and pulley. As economic development continues in cities across the country, urban forestry is designed to keep as many trees and other natural vegetation in a city or town. She said the best way to think about that term: building infrastructure with the smallest impact on the environment.

"In the field of urban forestry, street part management is very important, so for the kids to understand actually how to do maintenance on trees, a portion of that is how to get up in the canopy," Dr. Jean-Philippe added.

So this really a class of ups and downs, quite literally, for students like Wyatt.

"It takes a little bit. It's not too hard when you get the hang of it," he said.
