Lahopuuinventoinnin menetelmien vertailu Nuuksion ulkoilualueilla

Abstract: Tutkimuksessa vertailtiin nykyisin sovellettuja inventointimenetelmiä (ympyräkoeala-ja kaistainventointi) linja-leikkaus-otantaan (Line Intersect Sampling LIS) lahopuun inventoinnissa. Tarkoitus oli vertailla näiden kahden inventointitavan käyttökelpoisuutta, tuottavuutta ja luotettavuutta Nuuksion ulkoilualueella tehdyssä testissä. Testissä kaikille alueille laskettiin kaksi tai kolme riippumatonta inventointitulosta eri menetelmillä. LIS-menetelmässä tehtyjen havaintojen määrä (yhtä aluetta lukuun ottamatta)… Show more

“…We used line intersect sampling (LIS) and sector sampling (also called belt sampling) (Van Wagner, 1968;Shiver and Borders, 1996;Kangas et al, 2004) to measure the above-ground dead wood on the islands. The length of the line was determined in relation to the size of the forested area of each island: 50 m of line was surveyed for each forested hectare.…”

“…Traditional methods of measuring and modelling these attributes have been expensive and of low accuracy, because dead trees are rare and their existence is clustered (Kangas et al, 2004). Modelling techniques for the utilisation of inventory data have also been applied to the determination of the amount of CWD.…”

“…Dead wood is sampled in various ways. The most suitable method depends on the abundance and spatial distribution of dead wood, as well as on the target tree type (standing or downed) (Kangas et al 2004). The method should also be cost-efficient, robust for measurement error and simple to use.…”
