Quick Summary

Modern zoos are far more than the collections you might remember from childhood. Today’s accredited zoos, aquariums, and sanctuaries focus on:

  • Animal welfare: Ensuring animals are healthy, comfortable, and able to display natural behaviors.
  • Conservation: Supporting endangered species through breeding and reintroduction programs.
  • Education: Teaching millions about wildlife and environmental stewardship.
  • Research: Advancing science in nutrition, veterinary care, and behavior.

By supporting reputable zoos, you contribute to better care for both captive and wild animals. Read on to learn more

What Types of Animal Facilities Exist?

Not all zoos are the same. Facilities range in focus, mission, and the types of animals they house:

  • Zoos & Aquariums: Conservation and education-focused.

  • Safari Parks: Large outdoor habitats for public viewing and animal care.

  • Sanctuaries & Rehabilitation Centers: Provide refuge for rescued or injured animals.

  • Wildlife Rescues: Temporary care before release into the wild.

Example: The California Wolf Center is one of only 60 facilities in the world giving refuge to the critically endangered Mexican Gray Wolf like Durango and his brother Thor

What Does Accreditation Mean?

Accreditation ensures accountability where laws may be insufficient. Key organizations include:

Accreditation involves rigorous reviews, site inspections, and ongoing compliance with welfare and conservation standards.

Where Do Zoo Animals Come From?

  • Most animals come from species survival programs and controlled breeding within zoos.

  • TAGs (Taxon Advisory Groups) guide sustainable population management.

  • Sanctuaries often house permanent residents rescued from neglect or illegal ownership.

How Zoos Ensure Animal Welfare

Animal welfare is measured by mental, emotional, and physical health over time. Accredited zoos:

  • Promote species-typical behaviors and cognitive enrichment.

  • Provide safe, comfortable, and naturalistic habitats.

  • Monitor ongoing mental and physical health with veterinary teams.

Animal Enrichment: Five main categories stimulate natural behaviors:

  1. Sensory

  2. Environmental

  3. Forage/Feeding

  4. Occupational

  5. Play

Example: Brown bears practice their skills at getting favored foods out of difficult situations by trying to get some fruit out of a heavy duty barrel with small holes cut in the sides

Health, Nutrition, and Veterinary Care

  • Zoos often feature full-scale veterinary hospitals for examinations, vaccinations, and specialized care.

  • Nutrition programs are science-based, with research guiding diets and supplements.

  • Animals may receive physical therapy or treatments like chemotherapy if needed.

Education & Conservation Programs

Zoos educate millions about wildlife:

  • AZA-accredited institutions teach 180 million visitors, including 51 million students.

  • Programs cover STEM, local ecosystems, and global conservation.

  • Exhibits are designed by biogeography, grouping species by natural habitats.

How Zoos Help Endangered Species

Zoos support conservation via:

  • Reintroduction Programs: Releasing rehabilitated animals into the wild.

  • Rescue Programs: Providing safe homes for injured or threatened animals.

Example: California condors were brought back from 22 individuals in the wild to over 400 today thanks to SSP programs.

Scientific Research

Zoos conduct studies in:

  • Veterinary medicine

  • Nutrition

  • Animal behavior

  • Conservation techniques

Citizen science programs allow public participation in wildlife monitoring, supporting both education and research.
