Metsanduse arengukavad toovad välja, et vajalik on tõsta metsamajandamise konkurentsivõimet ja jätkusuutlikust, mis tagavad metsadele hea seisundi ning teenivad metsaomanike ja ühiskonna huve tervikuna.
Käesoleva uurimustöö ajendiks on metsamajandamise efektiivsuse tõstmine, metsamajandamise mõju keskkonnale ja laiemalt tulevaste kliimaeesmärkide saavutamise vajadus.
Metsakorraldajad juhinduvad oma töös metsakorralduse juhendis (MKJ) seatud inventeerimise tingimustest, peavad arvestama metsaomanike soovidega ja riikliku metsaregistri spetsialistide tõlgendusi õigusaktide kohta.
Tavapraktikas toimub metsaeraldise moodustamine ortofotode järgi kameraalselt enne välitöid arvutis ja hiljem piiride täpsustamisena looduses. Metsakorraldustööde käigus moodustatud eraldiste arvu suurenemine ja eraldise keskmise pindala vähenemise mõju on käesoleva uurimustöö sisuks.
Lõputöö eesmärgiks oli teada saada kui palju tehakse metsakorralduses metsaeraldisi rohkem kui MKJ nõuab ja mis on väikeste, alla 0,5 ha suuruste, eraldiste moodustamise põhjusteks. Töö esimene osa sisaldab statistilist analüüsi moodustatud metsaeraldiste arvust ja keskmisest pindalast erametsas, võrdlust RMK-ga ja teises osas on vaatluse alla võetud eraldiste arvu mõju analüüs ja eraldiste moodustamise põhjused. Analüüsis on kokku kasutatud 200 eraldist mille pindala on väiksem kui 0,5 ha ja välja toodud kas eraldise moodustamine oli põhjendatud või mitte. 31 metsakorraldajaga tehti internetiküsitlus selgitamaks välja mis on eraldise moodustamise põhjusteks.
Töö tulemusel selgus, et metsakorraldajad teevad tihti rohkem eraldisi harjumusest või oskamatusest ette näha selle hilisemat mõju kogu metsamajanduse sektorile tervikuna.
Forestry development programmes point out that there is a need to increase the competitiveness and sustainability of forest management, to ensure a good condition of forests and serve the interests of forest owners and society as a whole. This study is motivated by increasing the efficiency of forest management, the impact of management on the environment and, more broadly, the need to achieve future climate goals. Surveyors are guided in their work by the inventory conditions set in the forest management regulations, and should take into account the wishes of the forest owners and the interpretations of legislation by the specialists of the state forest registry. In standard practice, the delineation of the forest sub-compartments is done according to orthophotos before fieldwork on the computer and later specifying the boundaries in the field. The increase in the number of sub-compartments formed during forest inventoty and the effect of decreasing average sub-compartment size is the content of this study. The aim of the thesis was to find out how much more forest allocations are made in forest management than the regulations require and what is its effect. The first part of the work contains a statistical analysis of the number of forest sub-compartments formed and the average area in a private forest, a comparison with the state forests (RMK), and the second part contains an analysis of the impact of the number of sub-compartments and the reasons for the formation of small sub-compartments.. Results of the study suggest that forest surveyors often make small sub-compartments out of habit or inability to see its later impact on the entire forest management sector.
