Plants Biodiversity of Jobolarangan Forest Mount Lawu: 1. Cryptogamae

Abstract

The objectives of the research were to make: (1) a list of Cryptogamic plants at Jobolarangan forest in mount Lawu, and (2) the actual condition of biodiversity conservation of the plants. All Cryptogamic plants on the forest were studied. The procedures of data collection were including species collection in the field, make up herbaria, observation of flora vegetation using transect method, morphology observation in the laboratory, and interview to residents and government administrations. The results showed that in the forest were found 77 species Cryptogamic plants, consisting of 27 species of fungi, 5 species of lichens, 20 species of Bryophyta and 25 species of Pterydophyta. Government and residents had successfully conserved the forest; however fire and illegal logging damaged another part.

Population, habitat characteristic, and modelling of Endangered Orchid, Paphiopedilum javanicum in Mt. Lawu, Java, Indonesia

“…It consists of a small mountainous range with plenty of peaks. Humid winds are coming all year round without obstacle and turn into raindrops making the region the main catchment area (Setyawan and Sugiyarto 2001). Moreover, the forest type has a mixed forest that human activities have not fragmented.…”

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

“…Very distinctive forest physiography has a distinctive life form as well. One of the characteristics of protected forests and production forests in Java is the composition of the species of pine Pinus merkusii and puspa Schiima wallichii (Setyawan and Sugiyarto 2001). The highest distribution of mixed forest area was founded at Kayupuring and the highest distribution of pine forest and puspa forest were founded at Tlogohendro (Figure 2).…”

“…The resilience of the ecosystem can be stated as an emergent ecosystems attribute, which is endowed by multiple levels' biodiversity (Wheeler et al 2016;Komolafe et al 2020;Kiat et al 2020). Tropical forests are known as the most diverse and important terrestrial ecosystems, which serve a vital function in the global carbon cycle and being threatened by increased anthropogenic effects (Setyawan and Sugiyarto 2001;Vachnadze 2016;Komolafe et al 2020). The tropical rainforest is the richest biological community that has the complex interaction between ecosystem services and biodiversity to human well-being-resilience (Giriraj et al 2008;Naidu and Kumar 2016;Fedele et al 2017;Vacek et al 2019).…”

Species diversity of Selaginella in Mount Lawu, Java, Indonesia

“…Korth., although this later species is probably non-native in Mount Lawu (Steenis 1972). Several studies on plant diversity in Mount Lawu have been conducted, for example: fungi (Ilyas 2007), cryptogamae (Setyawan and Sugiyarto 2001), spermatophytes (Sutarno et al 2001), epiphytic plants (Setyawan 2000), epiphytic orchids (Marsusi 2001;Yulia et al 2011), epiphytic medicinal plants (Samsali 2008), fruit plants Rubus (Setyawan 1999), medicinal herb Plantago major (Sugiyarto et al 2006), Vanda tricolor orchid (Suparno-Putri 2013), home-garden plants (Harsono 2001), plants of Cemorosewu (Khussurur 2006), etc. This region has been proposed as a national park (Setyawan and Sutarno 2000;Setyawan 2001;Sriyanto 2003;Setyawan and Dirgahayu 2005;WDPA 2010).…”

“…Mountainous region with humid climate and abundant water sources throughout the year is a hotspot for its diversity. Research on species diversity of Selaginella in Mount Lawu had never been conducted before, but there have been reports of the presence of S. ornata (Setyawan and Sugiyarto 2001) and S. opaca (Setyawan 2009). The observation on the Herbarium Bogoriense (BO) collections have found three Selaginella species of Mount Lawu, namely: S. aristata, S. opaca, and S. involvens (ADS 2012, pers.…”
