Zoos are one of the most visited tourist and leisure attractions. After all the important Central-European zoos closed in the spring of 2020 due to the COVID-19 pandemic, a few weeks later they started to re-open.
The main goal of this article is to evaluate how the number of visits developed after the first zoo re-openings and what specific factors limited attendances the most after the reopening, using the example of Czech zoos in May and June 2020. In addition to the information available on zoos' online communication channels, the authors' questionnaire survey data and attendance data provided by the zoos were used.
The results indicate that the attendance was reduced the most by the obligation to buy tickets online, by the closure of state borders, and by a low limit on daily maximum number of visitors allowed. Different approaches to restricting zoos' capacity are discussed and the use of the maximum number of people by surface area of visitor routes at one time to limit attendance is recommended.
In the future, this could be a key factor for sustainability of many zoos.
