foreign species. The indigenous species included a Scotch Pine (Pinus Silvestris L.), Black Pine (Pinus Nigra Arn.) and Spruce (Picea abies Karsten), and the foreign species were European Larch (Larix decidua Mill.), Weymouth Pine (Pinus strobus L.) and Douglas Fir (Pseudotsuga taxifolia var. viridis Asch, et Gr.). This paper presents the results of the 10-year development of plants of the aforementioned species, as follows: — Indigenous species demonstrated the highest survival rate, in the first place Spruce and Black Pine, followed by Scotsch Pine and Weymounth Pine, Significantly lower survival rate was found in European Larch and Douglas Fir; — The greatest height was reached by the European Larch (as a fast growing species when young) and the smallest by Spruce (as a slow growing species when young); — The biggest DBH was reached by the Weymouth Pine and Scotch Pine at the following locations — Surduk, Slatki potok and Lokve, while Douglas Fir, Scotch Pine and European Larch reached the bigest DBH at Durgutovica. At allocations Spruce has the smallest DBH. As a matter of interest, the 5-year development of these species at the same plot was presented in the Šumarski list 1979, No. 9—10, pages 433—443. U »Šumarskom listu« o duglaziji pisano je: — 1933. god. u br. 10: O zelenoj i plavoj Duglaziji s naročitim obzirom na bolest Rhabdocline (M. Anić), i — 1960. god., u br. 11/12: Duglazija kao vrsta ekonomskih sastojina na degradiranom dijelu Krasa (O. Piškorić). Osim ovih većih članaka već od 1880. godine nalazi se više bilježaka o ovoj vrsti, a u publikaciji »Pola stoljeća šumarstva« (Zagreb 1926) o duglaziji kod nas ima podataka u članku J. Urbasa: Eksote u gozdnem gospodarstvu Slovenije«. V´ |
