Community structure of Korean fir (Abies koreana) snag‐dwelling arthropods on Hallasan National Park, Jeju Island, Korea

Abstract

AbstractWe executed this research to understand the importance of decaying woods as the diverse arthropods' habitat in Abies koreana forests of Mt. Hallasan, Korea, from 2013 April to 2014 July. We discriminated the Abies koreana forests into one live stage and three decay stages in three blocks (Sungpanak, Yeongsil, Donnaeko) with three replicates and collected arthropods using an emergence trap per tree. We also used the different slope, altitude, decay stage and characteristics of dead wood as statistical variables. As A result, a total of six classes 23 orders 99 families 224 species (69,674 individuals) were collected from 282 emergence traps. We found that there were significant differences in abundance among decay stages and study sites. Our research results would be relevant for developing the ecologically sustainable forest management strategies and we expect these results would be used as the basic data for the forest management plans of Abies koreana.
