My main interest is botany (with a focus on alien species) but I always strive to expand my knowledge of other organisms as well. I studied Conservation Biology and Biodiversity Management at the University of Vienna and work in the field of nature conservation.


Feel free to ask for an explanation for one of my IDs, I'll gladly provide one.

You can tag me if you are looking for an identification, I am happy to help! But please understand that my main focus are vascular plants in Central Europe and my knowledge in other parts of the world is limited.

Please only agree with an ID by others if you can confirm yourself that it is correct. Everyone can make mistakes and blindly agreeing might lead to a misidentified Research Grade observation.
