Analysis of the Distribution and Characteristics of Invasive Plants using Plant Social Networks

Abstract

Globally, Invasive Alien Plants (IAPs) are recognized as a major factor in biodiversity loss. Recently, the influx of exotic plants has been accelerated due to climate change, leading to an increase in concerns and worries about the decline of biodiversity. Mudeungsan National Park and Geumdangsan, which is located about 11 km away in a straight line, have much smaller areas and fewer visitors. Although IAPs are recognized as a major factor in the decline of biodiversity, recent research has shown that they can interact positively or negatively with native species in their habitats. The results of this study showed that the number of IAP species in both Mudeungsan national park and geumdangsan was similar, with 25 out of 533 taxa in Mudeungsan and 26 out of 304 taxa in Geumdangsan. The plant society network was analyzed using Gephi 0.9.7. The results of the interspecies association showed that Erigeron annuus (L.) Pers., Robinia pseudoacacia L., and Ambrosia artemisiifolia L. had many correlations with native plant species, and native plant species such as Artemisia indica willd., Persicaria filiformis (Thunb.) Nakai ex T.Mori, Pueraria lobata (Willd.) Ohwi, and Rosa multiflora Thunb. showed high compatibility with IAP. Additionally, Robinia pseudoacacia was confirmed to be a species suitable for artificial cultivation, and Erigeron annuus was suggested as an IAP Indicator because it plays an important role as a bridge in the boundary between the forest edge and the central area.
