Analiza preživetja in okrevanja dreves po žledolomu [Elektronski vir] : diplomsko delo - visokošolski strokovni študij - 1. stopnja = Analysis of the survival and recovery of trees after an ice storm : B. Sc. Thesis - Professional Study ProgrammesNovak, Alen, gozdarAnalizirali smo preživetje in okrevanje dreves po žledolomu, ki se je zgodil med 30. januarjem in 10. februarjem 2014. Analizo smo izvedli 9 vegetacijskih dob po žledolomu, ter primerjali nekatere ... rezultate z analizo, ki je bila izvedena 3 vegetacijske dobe po omenjeni ujmi. Na dveh različnih lokacijah po Sloveniji, kjer so že bile izvedene meritve leta 2017, smo na vsaki lokaciji v več vzporednih transektih postavili 20 raziskovalnih ploskev. Skupno smo analizirali 406 dreves. V analizo so bile uvrščene 4 drevesne vrste in sicer: bukev, gorski javor, graden in pravi kostanj. Ugotovili smo, da se je v primerjavi z letom 2017 mortaliteta povečala in sicer pri bukvi za 3,7 %, gorskemu javorju za 3,6 %, pravemu kostanju za 2,4 % ter gradnu za 16,7 %. Z večanjem prsnega premera se je mortaliteta zmanjševala, prav vsa odmrla drevesa pa so enako, kot pri popisu iz leta 2017 imela več kot 75 % poškodovane krošnje. Ugotovili smo tudi, da se je številčnost epikormskih poganjkov na deblu pri drevesih v povprečju zmanjšala, v krošnji pa povečala, ter da se je dolžina poganjkov povečala tako na deblu kot v krošnji. Vpliva stopnje poškodovanosti na odganjanje na deblu nismo zaznali, ugotovili pa smo, da so drevesa z manjšimi poškodbami imela večjo jakost odganjanja poganjkov v krošnji.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [A.
