Detailed coverage of invasive species threatening livelihoods and the environment worldwide

Abstract

Weed occurrence at several arboreta of Korea and their vegetation analysis.

Abstract

Weed flora in four arboreta in Korea was studied. The TWINSPAN (two-way indicator species analysis) method allowed the weed community to be divided into 4 types - Digitaria sanguinalis-Cyperus amuricus, Digitaria sanguinalis-Artemisia princeps, Digitaria sanguinalis-Setaria viridis, and Digitaria sanguinalis-Arthraxon hispidus communities. The results of the correlation between environmental characteristics and weed community by detrended canonical correspondence analysis ordination method showed that Digitaria sanguinalis-Cyperus amuricus community had high organic matter and available phosphorus concentrations, while the Digitaria sanguinalis-Arthraxon hispidus community had high magnesium and available phosphorus concentrations. The Digitaria sanguinalis-Artemisia princeps community had high magnesium concentration, whereas the Digitaria sanguinalis-Setaria viridis community had low magnesium concentration.
