“…Another study at Central Tapanuli also observed the diversity of understory plants in 2 management, i.e., agroforestry and monoculture. The result was classified as moderate (2.62 and 2.35, respectively; Muhdi et al 2020). This previous study held two plots with two repetitions: 20x20 m for the tree and 1x1 m for the seedling.…”

Abstract. Kurnianto AS, Haryadi NT, Dewi N, Miftachurrohmi, Rohmana A, Amal GI, Septiadi L, Firdaus AS, Magvira NL. 2023. Edge effects at multifunctional agro-landscapes in Jember, Indonesia, on the augmentation of butterfly diversity. Biodiversitas 24: 2231-2241. Butterflies are important pollinators and bioindicator communities in agro-landscapes. Assessing changes in butterfly communities, such as abundance and diversity, is essential in evaluating the response of butterflies to ecosystem disturbance. However, edge effects on agro-landscapes are highly influenced by land management. This study aims to objectively investigate the interactions between agroforestry management, including mono-shade, complex, and agroforestry-monoculture systems, with butterfly diversity to assess the impact of edge effects on butterfly communities. Sampling was conducted using Van Sommeren traps (T=150 cm; D=30 cm) baited with fermented bananas. Each trap was hung three meters high on a tree with three replicates in one location. Within 24 hours, the butterflies were collected, dried in an oven for 3x24 hours, and identified. The ecological indices were calculated using PAST 3.26, including the Shannon-Wiener index, the Simpson dominance index (D), the Simpson diversity index (1_D), the Margalef index, and the Evenness index. Therefore, 61 specimens, including 59 Nymphalidae and 2 Pieridae, were successfully collected. There are Nympahlidae families: Amathusia phidippus Linnaeus, 1763 (1), Elymnias casiphone Hübner, 1824 (2), Elymnias hypermnestra Linnaeus, 1763 (2), Euthalia aconthea Cramer, 1779 (1), Euthalia monina Fabricius, 1787 (1), Junonia atlites Linnaeus, 1763 (1), Junonia iphita Cramer, 1782 (1), Lethe europa Fabricius, 1775 (1), Melanitis leda Linnaeus, 1758 (24), Melanitis phedima Cramer, 1782 (4), Mycalesis fuscum Felder, 1860 (2), Mycalesis horsfieldi Moore, 1892 (1), Mycalesis janardana Moore, 1857 (6), Mycalesis nala Felder, 1859 (1), Mycaleses perseus Fabricius, 1775 (1), Mycalesis sudra Felder, 1867 (2), Orsotriaena cinerea Butler, 1867 (1), Orsotriaena medus Fabricius, 1775 (2), Polyura athamas Drury, 1773 (3), Polyura schreiberi Godart, 1824 (1), Tanaecia trigerta Moore, 1857 (1). There are families Pieridae: Leptosia nina Fabricius, 1793 (1), Eurema blanda Boisduval, 1836 (2). Comparison between complex and monoculture sites showed substantial differences. Meanwhile, there was no significant difference between mono-shade and monoculture sites. Butterfly diversity at the three locations was categorized as moderate. The highest diversity was observed in mono-shade sites. The three similarity indices showed that the agroforestry complex and monoculture locations have high similarity. Melanitis leda Linnaeus, 1758 was found in 3 sites and commonly found in complex sites (16), followed by monoculture (6) and mono-shade (2). This study indicated that edge effects have a significant influence, especially on the diversity of butterflies in the monoculture area.

“…Vice versa, the largest carbon sequestration can be contributed by the restoration of degraded and deforested lands to form primary and secondary forests (Basyuni et al 2021). Rubber agroforest also contains biodiversity since it will develop into a secondary forest despite the vegetation community and biomass being dominated by rubber trees (Beukema et al 2007;Muhdi et al 2020;Siswo et al 2022).…”

Abstract. Eddy S, Rizal S, Kartika T, Sari KJ. 2023. Vegetation analysis and ethnobotanical study of rubber agroforests in South Sumatra, Indonesia 24: 2276-2283. Rubber agroforests (RA) play essential roles in conserving plant biodiversity and delivering ecosystem services while providing socio-economic benefits to local communities. This study aims to examine the composition and structure of vegetation and to explore the ethnobotanical uses of plants in rubber agroforests located in Southern Tempirai Village, North Penukal Sub-district, Penukal Abab Lematang Ilir (PALI) District, South Sumatra, Indonesia. Vegetation data were collected using the purposive sampling method in three different rubber agroforests by establishing transect lines and observation plots according to the plant life form (seedling, sapling, and tree) at each sampling point. Ethnobotanical data were collected through interviews with plant-using communities through a purposive sampling method. The results showed that there were 17 plant species belonging to 13 families documented in the studied area. The most dominant species at seedling stage (including understorey) was senduduk (Melastoma malabathricum) with an IVI (Important Value Index) of 38.79, while the most dominant species at sapling and tree layers was rubber (Hevea brasiliensis) with IVI of 185.48 and 300.00, respectively. In the rubber agroforests studied, the species diversity was classified as very low with a diversity index (H') value of 0.85. There are various ethnobotanical uses plants found in the rubber agroforest with the most common use by the community was for traditional medicines (Mimosa pudica, Melastoma malabathricum, Gleichenia linearis, Ageratum conyzoides, Piper betle, Stenochlaena palustris, Coffea sp., Salacca zalacca, Syzygium polyanthum, Sauropus androgynus, Imperata cylindrica, Areca catechu). Other uses were for food ingredients (Calamus sp., Coffea sp., Bambusa sp, Salacca zalacca, Syzygium polyanthum, Sauropus androgynus), building materials (Hevea brasiliensis, Areca catechu), and household furniture (Calamus sp., Bambusa sp.). This study enriches the understanding regarding the importance of rubber agroforest in conserving germplasm diversity and maintaining the ethnobotanical knowledge of local communities.

“…Böhnert et al (2016) revealed that jungle rubber provides a favorable environment for epiphytic species diversity, on par with forests. Furthermore, Muhdi et al (2020) found that jungle rubber has higher species richness than monoculture rubber. Unfortunately, these reports are generally limited to quantitative values of diversity such as species richness, diversity index, dominance index and importance value.…”

Abstract. Siswo, Yun CW, Kim H, Lee J, Atmoko BD, Brahmantya L. 2022. Assessing herb layer composition under jungle rubber in Sungai Manau Forest, Jambi, Indonesia: indicator species and tree regeneration potential. Biodiversitas 23: 5247-5257. Most of the post-logged forests in Sumatra have been transformed into various land cover types, including plantations and secondary forests. Among plantation systems, rubber agroforestry (jungle rubber) is preferable since it resembles natural forests, which still maintain high biodiversity. While previous studies have been focused on the floristic diversity, composition and structure of jungle rubber, limited research has investigated indicator species and tree regeneration in jungle rubber. This research aimed to compare herb layer composition including species diversity, indicator species and tree regeneration potential between jungle rubber (JF) and the existing natural growing forests, including undisturbed post-logging forest (UF), mixed regrowth forest (MF) and newly regrowth forest (NF), in Sungai Manau Forest, Jambi, Indonesia. We conducted a vegetation survey and subsequently analyzed the data using some comparative analyses, indicator species analysis and regeneration status analysis. Our results showed significant differences in herb layer communities among all land cover types (T= -18.91, p=0.000). Although JF and all-natural growing forests showed equal indices of diversity, each land cover type showed its own indicator species, reflecting their environmental conditions. However, indicator species for JF were mostly similar in character to that in MF with non-native semi-shade-tolerant species. Meanwhile, all indicator species for UF were native shade-tolerant species and the indicator species for NF were fully non-native shade-intolerant species. JF is also equal to MF in seedlings availability and tree regeneration potential by showing an equal number of seedling species and the number of individuals where most of the seedlings in both land cover types were pioneer species with “good regeneration ”status”. Our finding suggested that JF had a similar potential to MF in the succession process. Therefore, jungle rubber can be a good alternative when a plantation system is inevitable in a post-logging forest.
