Lehigh Valley Zoo located in the heart of the Trexler Nature Preserve, is home to more than 325 animal ambassadors representing over 125 species.

Founded in 1906 by General Harry C. Trexler, a local industrialist, the Trexler Nature Preserve has played a significant role in saving the North American bison from extinction by providing a place where both bison and elk could roam freely undisturbed. In 1935, the County of Lehigh took ownership of the Preserve and, in 1974, construction began on the Preserve’s 29-acre Zoo. In 2004, Lehigh Valley Zoological Society assumed management of the Zoo, as well as the daily management of the bison and elk herd and the palominos in the 1,100-acre Trexler Nature Preserve.
