Why Bioartsense?

Because I am a biologist with a creative, artistic heart who wants to combine both passions with sense and purpose.

For this reason, I want to capture the uniqueness of nature in my watercolours and at the same time support various animal and nature conservation projects. Because art is able to renew the connection between man and nature and to express the beauty, but also the vulnerability of the same.

Beech Forest Project by Wohllebens Waldakademie

Ancient beech forests are the rainforests of Europe, and similar to the tropics, they are in very bad shape. Today, we no longer find any primeval forests in Germany, and the old trees are also becoming increasingly rare: beech forests over 180 years old now only account for 0.16 percent of the land area. And even these small remnant areas continue to be managed, so that as a rule only one third of the trees remain in these old-growth forests. Deadwood, present in virgin forests at about 20,000 cubic metres of wood per square kilometre and an important habitat for 3,000 species of insects and fungi, is largely absent in managed forests.
