Matthias Hower







A tree technician Matthias Hower from Germany was visiting us last summer.

He was leading a seminar on tree care and assessment. He shared his experience on how to avoid tree damage during construction works, how to manage aging tree avenues and other examples from his work in Germany. 

Participants had an opportunity to work with dendrotomograph.  By transmitting and detecting sound signals it allows to obtain a colourful cross-sectional image of the trunk without harming the tree.


Creating a Society

Aims of the Society:

  • Connect like-minded people who share an interest in trees in urban spaces and beyond
  • Encourage life-long learning
  • Promote interdisciplinary cooperation
  • Promote the quality improvement of the environment

A city cannot be imagined without any trees, and tree is one of the most important elements of the open space of a city. However, a city cannot consist solely of trees, and there is a need of good cooperation between experts of various fields in order to achieve the best outcome. The founders of the SOCIETY OF ANNAS TREE SCHOOL are professionals of various fields mainly involved with and around trees. It is a unity of nature experts, forestry technicians, gardeners, landscape architects and tree care experts – arborists.
