Zoos are permanent facilities where wild animals are kept for the purpose of public display for a period of at least seven days per year.

The following are not considered zoos:

• circuses,
• pet stores,
• enclosures for keeping no more than five native species of hoofed game,
• facilities where no more than 20 animals of other wild species are kept.

The establishment, expansion, operation, and substantial modification of zoos require approval from the competent nature conservation authority. The approval is granted for specific facilities and specific operators and sets a maximum number of animals for each individual species.
