On April 7,2017, TIAA Financial Services of Princeton, NJ participated in EarthShare's Corporate Green Challenge. A large group of volunteers came out to the Mountain Lakes Preserve to assist in the construction of a deer fence. The area was previously clear-cut in order to stage equipment for the restoration of the Mountain Lakes dam. After the restoration was completed in 2012, the area was planted with native trees and shrubs. A deer fence was installed to prevent harsh deer browse on the newly planted natives. After many years, the fence was in need of replacement. That is where TIAA came in.
