Summary: The author discusses the achievements of botanical studies into the Austrian Pine species and gives a survey of its habitats in the world according to Delvoy. Thereafter he reviews the investigations performed in Yugoslavia in this field. He presents a concise review of these works and an outline map of distribution of the Austrian Pine species on the Balcans according to Dr. P. Fukarek. Then he discusses the geological substratum on which there occurs the Austrian Pine in Yugoslavia, as well as the Karst soil types on which thrives this tree species. He describes the conditions necessary for its growing as well as the rôle of Juniperus sp. in its spreading. He discusses its rôle in the reforestation of degraded Karst areas as well as the causes of frequent failures. The author classifies the failures into three groups, viz. climatic, mechanical and biological. In the climatic group the author discusses the question of the drought and its combating by agrotehnical measures. In the mechanical group he passes in review the errors when handling the seedlings as well as the errors during the afforestation. With the biological group he discusses the origin of seeds as well as the failures to be ascribed to the provenances of the Austrian Pine. In conclusion the author emphasizes the importance of the autochthonous habitats of the Austrian Pine to be used as seed sources.
