Poškodovanost smreke in razvoj gozdnih sestojev na raziskovalnih ploskvah na Pokljuki

Leta 2006 smo ponovili izmero dreves na dveh raziskovalnih ploskvah na Pokljuki, velikih 1 ha ter 0,8 ha, v starejšem in mlajšem smrekovem debeljaku.Na podlagi podatkov o zaporednih merjenjih dreves smo ocenili razvojgozdnega sestoja. Izmerili smo premere in višine dreves ter ocenili kakovostne znake dreves. Zgradba sestoja se v zadnjih petdesetih letih ni spremenila, ostaja enodobna in enomerna. Poškodbe vplivajo na vitalnost dreves. Osutost ter dolžina krošnje po pričakovanjih močno vplivata na intenzivnost debelinskega prirastka. Stopnje osutosti se po socialnih položajih razlikujejo.In 2006 we have repeated the measurement of trees on a research plots on Pokljuka, which are 1 and 0,8 hectares in size each, of older and younger spruce large timber stand. We have made an evaluation of the development of the forest stand on the basis of data on successive measurements. We have maesured diameters and heights of trees, and made an inventory of their quality signs. The composition of the stands did not changed in the last 50 years, it still remains evenaged and uniform forest structure. Damages on trees are effecting vitality. As expected the defoliation and lenght of crown has an influence on the intensity of the diameter increment. The degrees of defoliation differ according to social status
