Briefings

A 2026 Nottingham Trent University study analyzed 7,200 species across 613 zoos in 72 countries over 30 years. Researchers compared changes in animal holdings against species' conservation status, extinction risk, trade protections, and breeding program involvement. The study aims to identify which species face the greatest threats from zoo expansion versus conservation needs.

Key points

• Researchers at Nottingham Trent University conducted a 30-year longitudinal study covering 7,200 species across 613 zoos in 72 countries.
• The analysis compared shifts in zoo animal holdings directly against changes in species' conservation status, extinction risk, and international trade protections.

Context and limitations

Data covers only 72 countries and 613 zoos; findings are preliminary and subject to future validation.
