What is dendrology?

The Greeks called trees Dendron. And we call ourselves dendrologists, after the Greek language. We are primarily concerned with the study of trees and shrubs, but we are also interested in all related fields. From horticulture to modern urban planning, garden and landscape design, including our future climate requirements in the city and the countryside. We are also interested in environmental and nature conservation from a global perspective, as well as in species-specific knowledge and the study of forests and woodland.

On excursions and trips to the most diverse regions of our world, we also visit woody plants, arboreta, public and non-public parks, botanical and private gardens, as well as special collections of woody plants that are often not accessible to the general public. We are guided by recognised specialists, often in two or even three languages.

What do we want to achieve?

We have set ourselves the goal of imparting knowledge and enjoyment of native and foreign woody plants, promoting their protection and maintaining international contacts. The exchange across green and political borders is one of our main concerns. The enrichment of our personal experience and know-how is more than a coincidental side effect.

We also support or promote book projects, collections of woody plants or other «green» causes within the scope of our possibilities and objectives.
