Zgradba in razvoj gozdnih sestojev v pragozdnem ostanku Lopata
diplomsko delo - visokošolski strokovni študij
Abstract
Na območju Lopate smo ponovno premerili 54 vzorčnih ploskev na sistematični mreži 100 % 200 m. Površina posamezne ploskve je znašala 0,04 ha. Ploskve so bile prvič merjene leta 1972. Na vsaki ploskvi smo drevesom izmerili obseg v prsni višini, dvema drevesoma smo izmerili tudi višino ter zabeležili mrtvo drevje. Znotraj raziskovalnih ploskev smo postavili tudi štiri manjše ploskvice za popis pomladka. Skupno smo premerili 1.266 dreves, od katerih je bilo 1.040 bukovih dreves. Število dreves se je s 418 dreves/ha povečalo na 586 dreves/ha. Največ se je povečalo število bukev s 328 dreves/ha na 481 dreves/ha. V pomladku je prevladovala bukev (93 %). Delež bukve se bo v prihodnje krepil, saj smo v proučevani vrasti zabeležili kar 208,33 osebka/ha. Količina odmrlega drevja znaša 31,09m3/ha.

| Secondary abstract: | We have conducted repeated measurements and observations within 54 sample plots on a systematic grid 100 x 200 m. Every sample plot covered 0.04 ha. First measurements took place in 1972. On every plot we measured diameter at breast height of every tree, recorded total height of two trees and also evaluated and recorded volume of coarse woody debris. Within every research plot 4 little squares were set-up to inventory natural regeneration dynamics. 1266 trees have been measured in total, the majority of them, 1040, being beech trees. We have recorded an overall increase of 418 to 586 trees per hectare, specifically accounting the beech tree species increase from 328 to 481 trees per hectare. Beech was the dominating species in natural regeneration plots with 93 % presence with ever increasing share expected in the future, as we have recorded 208,33 specimens per hectare overall. Volume of coarse woody debris amounted to 31.09 m3/ha. |
