This paper explores the influence of higher forestry education and forestry science at the Faculty of Forestry of the University of Zagreb on the formation and preservation of forest wealth in the Republic of Croatia during the past 120 years as the basic, authentic, self-renewable, biologically diverse and distinctly natural element. In order to do so, we shall provide a survey of some significant achievements of the faculty and its distinguished professors by citing examples of important textbooks and scientific papers. In the year 2018, the Faculty of Forestry in Zagreb marked the 120th anniversary of its establishment. It was on October 20th, 1898, that the Academy of Forestry was founded within the University of Zagreb as the first higher forestry institution in Croatia and in the south-east of Europe. The continuity of higher forestry education at the University of Zagreb has been retained to date through the periods of activity of the Academy of Forestry (1898 - 1919), the Faculty of Agriculture and Forestry (1919-1946), the Agricultural-Forestry Faculty (1946 - 1960) and the Faculty of Forestry (1960 - to date). Three characteristic periods can be singled out in the development of forestry education and science at the Faculty of Forestry in Zagreb in the course of 120 years: the first half of the 20th century, the second half of the 20th century and the first half of the 21st century. The first half of the 20th century witnessed a surge in the Croatian forestry, which can primarily be attributed to the development of higher forestry education and science at the Academy of Forestry and the Faculty of Agriculture and Forestry of the University of Zagreb. Among the most important contributions of university forestry education and science in Croatia are the establishment of the Zagreb School of Silviculture and the beginnings of organized and systematic scientific research in forestry. The second half of the 20th century is characterized by the blossoming of higher forestry education and science in Croatia, which had a direct impact on the condition of forests and the development of practical forestry. During this period, the Croatian forestry, science and practice became an outstanding example of mutual cooperation and powerful development, which brought about an improvement in the condition of forests in Croatia as a whole. The forestry practice firmly adhered to the principles of the Zagreb School of Silviculture, an orientation towards natural regeneration, natural stand structure, and natural, diverse and stable forests. This trend has continued in the 21st century. The new age has given rise to vast changes and challenges in higher forestry education and science. The crisis of forestry, which has gradually been evolving over the past fifteen years, has had its repercussions on the basic activity of the Faculty: higher education and science. Today, the Faculty of Forestry is confronted with two serious challenges: lesser interest of young people in studying and a reduced intensity and scope of scientific research in forest ecosystems. There are no objective reasons for either of the above, however. Forests are the most widespread and the most important natural wealth in the continental part of the Republic of Croatia. There are currently a large number of job openings in forestry and urban forestry, as well as in nature and environment protection, and this trend will continue to rise in the future. The Croatian forest ecosystems are facing growing numbers of challenges and problems. On the other hand, there are fewer and fewer workers in forestry. In view of this, there is no reason for crisis in one of the most natural and oldest studies at the University of Zagreb. On the contrary, forestry experts have splendid prospects in today’s ecological, economic and social conditions. The task of the Faculty is to adjust itself and its basic products, experts in the management of forest ecosystems of the Republic of Croatia, to new challenges. Forestry practice and forestry science must work together, just as they have done throughout the long forestry history. Only be doing so will their development be ensured in accordance with the definition: forestry is a science, profession and art of managing and preserving forest ecosystems for the permanent benefit of man, society, environment and economy.
