If you keep vertebrates of specially protected species, you must notify the competent authority immediately. This also applies to a change in the of the animals, the relocation of the regular location and the labelling of the animals.
Species under special protection include, for example, monkeys, parrots, tortoises and giant snakes and various lizard species such as day geckos and chameleons. All European bird species are also included.
As a rule, an animal species is a specially protected species if it is included in the Wisia database of the Federal Agency for Nature Conservation (https://www.wisia.de/). You can search for the species there on the left-hand side under "Research" and "Enter search term (species name)". Invertebrates such as scorpions or spiders do not have to be reported. The vertebrates shown in the following list also do not have to be reported: https://www.gesetze-im-internet.de/bartschv_2005/anlage_5.html
In the event of changes to your stock, you must register new animals (e.g. including your own offspring) and deregister animals that are no longer in your stock (e.g. due to sale or death). If you give an animal to another person, you must deregister the animal and the new owner must register the animal.
You must also register if the identification of your animal changes (e.g. ring identification, transponder identification) or if you change the location of the animal (e.g. move to another city).
