I am a forester by profession. I received my education at the Secondary Forestry Technical School in Liptovský Hrádok and at the Forestry and Timber Academy in Zvolen. I started my professional career in the Tatra National Park in the area of Ticha and Kôprova dolina. Later, I taught at the Secondary Forestry School in Liptovský Hrádok (the perpetrator returns to the scene of the crime) and now I work in the private sector, but also with a forestry focus. I have always been close to nature, animals, plants and especially trees. When I started teaching dendrology at the high school of forestry, I thought it would be a good idea to create a photographic database of morphological features of domestic and foreign trees grown in our country. When I more or less succeeded, circumstances forced me to leave the school in Liptovský Hrádok. I first used the free space on Botany.cz and I try to present my more than twenty years of photographic efforts in the field of tree morphology (mainly domestic ones) on my website www.atlasdrevin.sk.
