Struktur Vegetasi Kawasan Hutan Pada Zona Ketinggian Berbeda di Kawasan Gunung Galunggung Kabupaten Tasikmalaya Jawa Barat

Abstract

ABSTRAKVegetasi Hutan di Kawasan Hutan Gunung Galunggung Kabupaten Tasikmalaya Jawa Barat telah dilakukan pada Maret – November 2016. Metode yang digunakan adalah metode survey. Pengumpulan data dilakukan dengan teknik plot kuadrat yang diletakan di sepanjang transek. Sebanyak 43 jenis tumbuhan telah ditemukan yang terbagi ke dalam kategori pohon dewasa, tiang, pancang, dan semai. Kategori pohon, tiang pancang dan semai berturut-turut ditemukan sebanyak sebanyak 12, 25, 23, dan 21 jenis. Kurai (Trema orientalis) adalah jenis yang menguasai pada kategori pohon, paku bagedor (Cyathea contaminans) pada kategori tiang, kiseureuh (Piper aduncum) pada kategori pancang, dan nangsi (Villebrunea rubescens) pada tingkat semai. Komposisi jenis vegetasi pada dua zona berbeda, tetapi jenis-jenis tumbuhan yang dominan pada dua zona tersebut hampir sama. Hutan Gunung Galunggung masih berada dalam kondisi yang belum klimaks, populasi dan strukturnya masih dalam tahap perkembangan/tahap sekunder. Hal ini ditandai dengan tingkat keanekaragamannya yang sedang dan ditemukannya jenis huru (Litsea sp.), puspa (Schima walichii), hamerang (Vernonia arborea), dan nangsi (Villebrunea rubescens), serta jenis lainnya yang merupakan karakteristik hutan hujan pegunungan yang berada pada tahap suksesi “seral”.ABSTRACTThe study of forest vegetation in the area of Galunggung Mountains, Tasikmalaya Regency, West Java have been carried out in March to November 2016. The method used is survey method. The data was collected teknic square plots placed along the transect. The research found as many as 43 in the plant species, which are divided into categories of tree, poles, saplings and seedlings. Kurai (Trema orientalis) is dominant species into tree categories, Paku bagedor (Cyathea contaminans) into poles, Kiseureuh (Piper aduncum) into saplings, and Nangsi (Villebrunea rubescens) into seedlings. The composition of vegetation types found in two different zones indicates a difference, but it can be said that the plant species are dominant in the two zones are almost the same. Galunggung forests are still in a state that has not climax, and the population structure is still in development (secondary stage). Marked with the current level of diversity and the discovery of Huru (Litsea sp.), Puspa (Schima walichii), Hamerang (Vernonia arborea), and Nangsi (Villebrunea rubescens), as well as other types that are characteristic of rain forest at mountian seral successional stage.Keywords: Vegetation, Rain Forest at Mountain, Seral Successional StageSitasi: Suryana, Iskandar, J., Parikesit, Partasasmita, R. dan Irawan, B.

Vegetation Analysis of the Secondary Forest Area of ​​Mount Merapi National Park

“…After the eruption, the condition of the vegetation that was directly affected in the Cangkringan Resort area was overgrown with various types of vegetation. According to (Suryana et al, 2018), one type of native forest vegetation such as Schima walichii is a sign of end-level secondary forest. the discovery of Schima walichii in MMNP shows that currently the MMNP Commission is in the process of going to old secondary forest.…”

Plant diversity of Petungkriyono Forest of Dieng Plateau, Central Java, Indonesia

“…It showed that the vertical structure in Petungkriyono forest was dominated by tolerant types that could live and survive for a long time as the understory types. The existence of all categories proved that the succession process was running in the Petungkriyono forest (Suryana et al 2018) The vertical analysis was dominated by wood density, canopy cover, and understory. The previous study in Dinagat Island showed that the forest structure with an elevation ranges from 750-929 m is the highest peak, with vegetation cover is estimated 70-90% and canopy cover is ranging from 10-40%.…”

“…The next step was to identify and compare to the identification book of species in the natural forest. The various publications were used as references to identify the observed and collected plants (Odum 1998;Giriraj et al 2008;Abedi and Pourbabaei 2010;Naidu and Kumar 2016;Kusumo 2016;MoEF 2017;Suryana 2018;Lillo et al 2019;Amiri 2019;Addi et al 2020;Lillo et al 2020).…”

Does Altitude and Forest Density Affect Economic Growth? a Case Study of Kalimantan Barat

“…In general, altitude can affect the area of forest cover in a room. Higher regions tend to have more comprehensive forest cover than lower areas (Suryana, Parikesit, & Iskandar, 2018). Naturally, the more elevated areas have more diverse vegetation.…”
