Although located in an urban area, the University of Lousiville's 309-acre park-like Belknap campus has over 2,500 trees representing over 130 species, many of which are native to our bioregion. UofL researchers and students have helped catalog over 1,740 individual trees just on the core of Belknap campus that represent a total of 117 species from 54 genera.

Take a self-guided 2-mile walking tour of some of the interesting and historical trees on Belknap campus!
