Abstract

Invasive plants are plants that can originate from outside the native area and can threaten ecosystem stability and cause disturbances that damage the structure, composition, and growth of native vegetation in an ecosystem. Likewise, the existence of invasive plants can have a negative impact to other plants that collected in the Bogor Botanical Gardens, affecting habitat conditions and the growth of other vegetation. Therefore, the objectives of this research were to know the pecies of invasive undergrowth, analyze the level of dominance and distribution patterns of each species of plant. The data was collected using the double plot method with a sampling intensity of 2%, each plot measuring 2 m x 2 m, then the data was analyzed for density, frequency, Important Value Index, and Morisita Index. The data was collected using the double plot method with a sampling intensity of 2% that each plot measuring 2 m x 2 m, covering individual number of undergrowth, organ morphus of each species of undergrowth and then identification was carried out, then analyzed for density, frequency, Importance Value Index, and Morisita Index. The results of this research found 10 species of invasive undergrowth, namely Ageratum conyzoides, Asystasia intrusa, Cyanthillium cinereum, Dioscorea bulbifera, Elephantopus scaber, Epipremnum pinnatum, Mikania micrantha, Spermacoce alata, Synedrella nodiflora, and Syngonium podophyllum. There are 2 species of invasive undergrowth that are the most dominant, namely Dioscorea bulbifera and Elephantopus scaber with the highest Important Value Index and have a clustered distribution pattern which indicates strong competition between plants, but have good competitive ability, adaptation, and tolerance to environmental conditions.
