Ugotavljanje stanja okolja s popisi epifitskih lišajev v gozdovih območne enote Postojna v letu 2007 : diplomsko delo - visokošolski strokovni študij

Vidmar, Andrej (author), Batič, Franc (mentor), Kovač, Marko (comentor)

V diplomski nalogi je predstavljena metoda popisa epifitskih lišajev za potrebe ugotavljanja stanja okolja v gozdovih območne enote Postojna. V nalogije najprej podana predstavitev območne enote Postojna. Sledi obrazložitev metode dela popisa lišajev - ocenjevanje prisotnosti in pokrovnosti lišajev na drevesnih vrstah na posameznih ploskvah. V rezultatih so podani izračuni mediane relativne pokrovnosti (obrasti), s katerimi se je interpretiralo stanje onesnaženosti zraka in s tem stanje okolja. Rezultati stanja obrasti kažejo na slabše stanje okolja, vendar se sprašujemo, če je dejansko stanje res tako slabo oz. le zadovoljivo. Razloge za slabše rezultategre iskati tudi v metodi ter izvajanju le-te. Splošna ugotovitev pa je bila, da stanja okolja v gozdovih na območju raziskave po tej metodi ni mogoče povsem določiti.

• Title: Assesment of environmental condition by epiphytic lichens in forests of Postojna regional unit of Forestry service of Slovenia in 2007 : graduation thesis - higher professional studies

Abstract

The Graduation Thesis presents the method of inventory of epiphytic lichens for the assessment of the environmental condition in the forest area unit of Postojna. The first part of the Thesis is the presentation of the regional unit of Postojna. Then it is followed by the explanation of the method of the inventory of epiphytic lichens - assessing the presence and cover of lichens on tree species on particular surfaces. The results are given by calculations of median relative cover, which helps for the intepretation of the state of air pollution and the state of the environment. The results show the state of cover as worse environmental condition, but there is a question if the actual state is really so bad or only satisfactory. The reasons for the poor results lie in the method and implementation of it. The general statement was that the environmental situation in the forests in the area of the research, can not be fully determined by this method.
