Abstract. Cahyanto T, Efendi M, Shofara RM. 2019. Short Communication: Floristic survey of vascular plant in the submontane forest of Mt. Burangrang Nature Reserve, West Java, Indonesia. Biodiversitas 20: 2197-2205. A floristic survey was conducted in submontane forest of Block Pulus ​​Mount Burangrang West Java. The objectives of the study were to inventory vascular plant and do quantitative measurements of floristic composition as well as their structure vegetation in the submontane forest of Nature Reserves Mt. Burangrang, Purwakarta West Java. Samples were recorded using exploration methods, in the hiking traill of Mt. Burangrang, from 946 to 1110 m asl. Vegetation analysis was done using sampling plots methods, with plot size of 500 m2 in four locations. Result was that 208 species of vascular plant consisting of basal family of angiosperm (1 species), magnoliids (21 species), monocots (33 species), eudicots (1 species), superrosids (1 species), rosids (74 species), superasterids (5 species), and asterids (47), added with 25 species of pterydophytes were found in the area. The three families of plants are Lauraceae (10 species), Urticaceae (9 species), and Rubiaceae (8 species) dominating those areas. Fourteen species belong to IUCN red list: Least concern/LC (12 species), Vulnerable/VU (1 species), and endangered/EN (1 species). Furthermore, Castanopsis argentea A.DC, Pinanga javana Blume and Amorphophallus decus-silvae Backer & Aldrew belonging to protected plants are also found in the area. Based on the assessment of analysis vegetation, the forest has experienced disturbance, the density of trees is commonly low and has a lot of gaps. Many vacant lots are found. On the other side, there is the presence of invasive plant species that may slow down a succession into climax growth of local plant.

Tree Communities and Aboveground Biomass in the Submontane Zone of Ketambe Resort, Mount Leuser National Park, Aceh

“…Based on the families composition, Lauraceae and Myrtaceae have the highest number of tree species in both sites, followed by Euphorbiaceae and Moraceae. Lauraceae and Myrtaceae families are the richest families in the primary submontane to montane forest of Malesia, as reported by Culmsee et al (2011) in Lore Lindu Sulawesi and Cahyanto et al (2019) in Mt. Tilu, West Java.…”

“…Ketambe. If we compared with the forest vegetation studies in Java Island, Dipterocarpaceae recorded in lowland natural forest, as reported in Bodogol, Gede Pangrango National Park (Helmi et al, 2009) , and were not found in the submontane zone, as reported by Cahyanto et al (2019) in the Mt. Burangrang, Purwaningsih et al (2017) in Mt.…”

“…A high abundance of fast growing species is secondary forests characteristics, in contrast to the primary forest (Chazdon et al, 2010) . Gaps also could cause the invasive species plant growth that slows down the forest succession (Cahyanto et al, 2019;Junaedi & Nasution, 2018) .…”

Zonation Drives The Abundance of Understory Exotic Plant Species in Ir. Djuanda Forest Park, West Java

“…Seventy-three species belonging to 38 families were found within the plot, dominated by Araceae and Moraceae families (Table 2 and Table 3). Araceae and Moraceae were the largest families in angiosperms, which have widely distributed from lowland up to montane forest (Backer & van den Brink Jr, 1965, 1968Berg & Corner, 2005), particularly in secondary forest (e.g., Cahyanto et al, 2019;Mutaqien et al, 2008;Widodo & Wibowo, 2012). Compared to other FP in Java and Sumatera, Ir.…”

“…The abundance of exotic understory species is an indicator for vegetation succession, as reported by Grant & Loneragan (2001). At the sapling level, the understory woody-form can be used to predict the stand regeneration (Afrianto et al, 2016;Cahyanto et al, 2019;de Carvalho et al, 2017;Irfani, 2016;Rasnovi, 2006;Susanti, 2014).…”
