Hall lepp (Alnus incana (L.) Moench) on Eestis laialt levinud kodumaine puuliik, mille
puistud katavad 8,9% metsamaast. Metsaomanike huvi hall-lepikute majandamise vastu on
madal, sest halli lepa puit on odav.
Aastal 2018 tõusid puidusortimentide hinnad hüppeliselt. Sellest tulenevalt tekkis töö autoril
küsimus: kas pärast suurt puidu kokkuostuhinna tõusu tasuks eelistada hall-lepikuid
kuusikutele? Lõputöö eesmärk on selgitada, kas võrreldes hariliku kuuse puistuga on hall lepiku kasvatamine majanduslikult tasuvam või mitte. Töös arvutati hall-lepiku ja kuusiku
majandamise 60 aasta puhasnüüdisväärtus, sisemine tasuvuslävi ja pikaajaline keskmine
tulu.
Hall-lepiku ja hariliku kuuse majandamise tasuvuse võrdlemiseks kasutati kolme näitajat:
puhasnüüdisväärtus, sisemine tasuvuslävi ja pikaajaline keskmine tulu. Puistu
kasvumudelite saamiseks kasutati Eesti riigimetsa puistute kõrguse, diameetri ja tagavara
vanuseridade diferentsmudelit.
Puhasnüüdisväärtuse meetodil saime teada, et hall-lepiku NPV on 1842,3 eurot ja kuusiku
NPV on 3806,14 eurot. Sisemine tasuvuslävi hall-lepikus on 9,51% ja kuusikus 4,54%.
Hall-lepiku pikaajaline keskmine tulu on 76,4 eurot/ha/a ja kuusikus 242,3 eurot/ha/a.
Pikaajaline keskmine tulu ja puhasnüüdisväärtus näitavad, et võrreldes hall-lepikuga on
kuusikute kasvatamine majanduslikult tasuvam.
Grey alder (Alnus incana (L.) Moench) is a widespread domestic tree species in Estonia, with stands covering 8.9% of forest land. Forest owners interest in grey alder management is low because grey alder wood is cheap. In 2018, the prices of wood assortments went high. As a result of situation, author had a question: should grey alder be preferred to Norway spruce after increase of the purchase price of timer. The aim of the thesis is to find out whether grey alder is economically more profitable than Norway spruce. In thesis calculated the net present value, the internal rate of return and long-term average income of grey alder and Norway spruce. Three indicators were used to compare the management of grey alder and Norway spruce: the internal rate of return and long-term average income. The stand growth model was used to differentiate the height, diameter and reserve age series of Estonian state forest stands. Using the net present value method, we found out that the NPV of grey alder is 1842,3 euros and the NPV of the Norway source is 3806,14 euros. The internal rate of return in grey alder is 9,51% and in Norway spruce is 4,54%. The long-term average income of grey alder is 76,4 euros/ha/year and of Norway spruce 165,9 euros/ha/year. The long-term average income and net present value show that Norway spruce growing is more economically viable than grey alder.
