Abstract

V zgornjem delu doline Male Pišnice smo postavili stalne raziskovalne ploskve.Postavili smo vzorčno mrežo gostote 100*100 metrov v pasu od 1150 do 1800 metrov nad morjem. Posamezne ploskve so bile velike 500 m2. Skupno smo postavili 45 ploskev. Od tega je bilo 14 ploskev s prevladujočim macesnom, 31 ploskev pa je bilo v bukovih sestojih. Drevesom smo izmerili obseg v prsni višini, drugemu in tretjemu najdebelejšemu drevesu smo izmerili višino, ostaleparametre pa smo ocenili. Skupno smo izmerili 85 drevesnih višin. Pri popisu pomladka smo znotraj raziskovalnih ploskev postavili ploskvice za popispomladka. Površina macesnovih ploskev je obsegala 0,7 ha, bukovih pa 1,55ha. V izračune smo zajeli 1042 dreves in 285 osebkov pomladka. Gostota dreves je znašala 463 dreves/ha. Skupaj je pri pomlajevanju prevladovala bukev(44 %), sledili so macesen (16 %), jelka (15 %), smreka (4 %) in ostalo (21 %). Število dreves na hektar se z nadmorsko višino znižuje. Veliko dreves nad nadmorsko višino 1700 metrov je bilo pod debelinskim pragom 10 cm.

Secondary abstract:	A permanent research plot network of density 100*100 m was established in the upper part of the Mala Pisnica valley at 1150-1800 m above the sea level. 45 plots of 500 m2 each was measured; on 14 of them European larch trees prevailed (larch stratum) and 31 were prevailed by European beech (beech stratum). All trees on each plot were surveyed; the DBH was calculated througha measured circumference of each tree; heights of every second and third thickest tree on the plot were measured; additionally, some other parameters were estimated. To examine the regeneration, 4 small plots were established within each permanent plot. In total, 0.7 ha of larch stratum and 1.55 ha of beech stratum was surveyed. 1042 trees and 285 young trees in the regeneration layer were used for further calculations. In the average, the density of 463 trees per hectare was ascertained. In the regeneration layer, beech was the most common, representing 44 % of all individuals, and was followed by larch (16 %), silver fir (15 %) and spruce (4 %). The density measured by number of trees per hectare increased with higher altitude. Above 1700 m a.s.l. the majority of trees DBHs were smaller than the measuring threshold of 10 cm
