The Phoenix Zoo features Sumatran tigers in their "Isle of the Tiger" exhibit, participating in the Species Survival Plan (SSP) for conservation, with notable tigers like Joanne often in the news for their care, age (like Sari, one of the oldest), and playful antics, while promoting anti-poaching efforts to save wild tigers. They use "protected contact" for safety, with barriers between keepers and tigers, and have expanded habitats for these critically endangered big cats.
