The Edge is a newly designed exhibit modeled after the pine forests of Russia for the zoo's Amur tigers. Two yards with large pools and pathways that wander over visitors' heads provide enrichment and exercise for the tigers. This is the first of several rotational exhibits that will make up a new Asian Predators area, giving the zoo's other big cats larger and more dynamic habitats. It opened to the public in March 2017, replacing Wolf Pack Woods, which opened in 1988.
