Vpliv mortalitete in vrasti na razvojno dinamiko subalpinskih gozdov na Polšaku : diplomsko delo - univerzitetni študij = Influence of mortality and recruitment on subalpin forest dynamics in reserve Polšak : graduation thesis - university studiesVedenik, AndrejaRaziskava je potekala leta 2010 v gozdnem rezervatu Polšak, na Dleskovški planoti v Savinjskih Alpah. Namen raziskave je bil kvantificirati spremembe in opredeliti mehanizme sukcesijskega razvoja ... subalpinksih gozdov, ovrednotiti pretekli in sedanji režim motenj ter z ovrednotenjem vrasti in mortalitete kvantificirati hitrost in smer sukcesijskega razvoja. Ponovljena so bila snemanja štirih sestojev iz leta 1982 na višinah od 1420 m n. v. do 1650 m n. v. in sicer dva sestoja macesna, sestoj bukve, smreke in macesna ter sestoj smreke, macesna in jelke. V vseh sestojih se je število dreves zmanjšalo (od 5% do 27 %). V pomladku je prevladovala smreka, ki se je pomlajevala v treh sestojih, macesen pa le v enem. V vseh sestojih se je temeljnica povečala (od 16,5 % do 59 %). Pri smreki in macesnu je bilo opazno dobro preraščanje dreves zgornje plasti, medtem ko so drevesa spodnje plasti odmirala zaradi pomanjkanja svetlobe. Na podlagi rezultatov je razvidno, da je bil glavni dejavnik, ki je vplival na razvojno dinamiko obravnavanih sestojev, predvsem endogena mortaliteta, ki je posledica znotrajvrstnega in medvrstnega tekmovanja. Kljub temu ni bilo mogoče ugotoviti značilne spremembe v drevesni sestavi, predvsem v smeri prevlade sencozdržnih vrst. Rezultati raziskave kažejo, da razmere zadnjih 28 let niso dopuščale hitre spremembe v strukturi ali sestavi gozdnih sestojev.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [A.
