In 1990 she became a falconer at Wildpark Luneburger Heide and eventually was put in charge of several wolf packs at the park. She was involved with raising the wolves also. In the spring of 2010, Tanja was involved in flying to Canada and picking up several wolf pups to bring back to Europe. This was the culmination of the long fought for "Fresh Wolf Blood" project. A beautiful female wolf pup that she named Naaja ended up going back to Germany with Tanja.
Tanja is also a very dedicated and talented photographer, author and public speaker. Animals are the subject matter of course with wolves being her favorite. She also photographs other wildlife and domestic animals too. Her belief that supports her work is the total acceptance of the animals for who they really are void of any moral or romantic prejudices. And of course the natural affinity and love of animals that she was born with can be seen throughout everything she does.
