Denver Zoo is an 80-acre nonprofit zoological garden located in City Park of Denver, Colorado. Founded in 1896, it is operated by the Denver Zoological Foundation and funded in part by the Scientific and Cultural Facilities District (SCFD) in addition to ticket sales and private donations. It is the most visited paid attraction in Colorado. Denver Zoo was started with the donation of an orphaned American black bear. With the construction of Bear Mountain, it became the first zoo in the United States to use naturalistic zoo enclosures rather than cages with bars.
The zoo achieved ISO 14001 certification in 2009, was given the first AZA Green Award in 2011, and was named the "Greenest Zoo in the Country" at the World Renewable Energy Forum in 2012. In 2015, it was re-certified for ISO 14001 and achieved OHSAS 18001 certification, becoming only the fourth zoo in the world to get both certifications.
