Učinki različnih načinov izbiralnega redčenja na odziv izbranih dreves v smrekovo-bukovih sestojih na Mežakli : magistrsko delo : magistrski študij - 2. stopnja = Effects of difrent thinning regimes on crop trees response in spruce-beech strands on Mežakla : M. Sc. Thesis : Master Study ProgrammesMencinger, ValentinaLeta 2016 so izvedli tretjo meritev na raziskovalnih ploskvah v bukovih drogovnjakih na Mežakli, ki so bile zasnovane leta 2005. Preverjali so tri načine izbiralnega redčenja in kontrolo, kjer niso ... ukrepali: klasično izbiralno redčenje z običajno jakostjo (način dela 60), izbiralno redčenje s 50 % manj izbrancev in običajno jakostjo (način dela 30) ter izbiralno redčenje z 75 % zmanjšanjem števila izbrancev in močno jakostjo ukrepanja (način dela 15). Izbrancem so določili drevesno vrsto, izmerili premer, višino, dolžino čistega debla, prešteli število vej na prvih 4 in 8 m debla in določili asimetričnost, poškodovanost in sproščenost krošnje. Način dela 15 se je izkazal za najboljšega pri debelinskem prirastku, upadu dimenzijskega razmerja in povečanju velikosti krošnje. Način dela 30 je najbolj pozitivno vplival na višinski prirastek izbranih dreves in skupno število vej na prvih 8 m dolžine debla. Najmanjše zmanjšanje krošenj so opazili pri načinu dela 60. Velik vpliv na rezultate so imele ujme, zaradi katerih je med letoma 2005 in 2016 izpadlo 12,8 % izbrancev. Za najboljši način dela so izbrali način dela 30, za najmanj primernega pa se je izkazal način dela 15.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [V.
