If you would like to support the nature and zoo during the Corona period (of course also otherwise), I recommend adopting an animal sponsorship for one of the animals from 5 continents.
You can take on the sponsorship for 1 year or longer and costs between € 15 and € 250 per year. For the sponsorship you get a certificate, the name of the sponsor is recorded on a patent board and a free sponsorship ticket for a one-time visit to the park. This sponsorship is counted as a donation and is therefore tax-effective.
The amount of the donation is based on the species and the care and feed costs.
You can find out more on the website of the Brueggen Nature and Zoo or by phone.
