Vegetational and Structural Traits of Phytocoenosis of the Common Birch (Betula pendula Roth) on the Psunj Mountain Summary The daily growing need for pulpwod as a rew material for the production of paper has resulted in a tendency in Croatia to pay greater attention to the investigation and silviculture of the common birch; wood which is in great demand. This paper presents the investigation results on the possibility of raising this culture in the management unit Zapadni Psunj. In this management unit the Phytocoenosis Betulo-Quercetum petraeae illyricum Fuk. in 1959 covered a surface of approx. 500 ha, whille a further 350 ha are today overgrown with brush-wood, which is also quite suitable for raising birh stands. The average volume of woel for birch stands amounts to 158 n>"> per hectare, with a mean annual increment of 4 m:>. Figs. 1 and 2 Present the appearance of the birch stands today. Graph. 1 Presents the height curve for the common birch in the management unit of Zapadni Psunj. Graph. 2 Presents the distribution of the number of trees (N ha) and wood volume (M,ha) by diameter three expermiental plots for the birch (1). sessile-flowered oak (2). other species (3) and altogether (4). |
