“…At 6 months after planting (map), Balangeran was almost two times as high as Bintangur, while at 12 maps, it was three times as high as Bintangur. Similar trend was reported by Lampela et al (2017) who found that Balangeran had relative height increment of more than 100% at 1.5 years after planting. Table 1 shows that Bintangur had slower growth and lower survival rate.…”

“…Longer dry season and inundation during rainy season had less impact on Balangeran than on Bintangur. Similar result was also shown by Lampela et al (2017) when Balangeran was found as one of peat swamp native species that had great tolerance to both long dry season and inundation during the river flooding. According to Lavelle (1987), under an open area after clearing there will be dramatic changes observed in the temperature and moisture at surface soils.…”

Rachmat HH, Subiakto A. 2019. Initiating the establishment of commercial stand at Tasik Besar Serkap, Riau, Indonesia: An early growth assessment of two peat swamp tree species. Biodiversitas 20: 267-272. Degraded and converted peat swamp forest has enhanced the emission of CO2 and become one major contributor of huge greenhouse gas emission. Management unit at site level of KPH Tasik Besar Serkap covers a very wide area of more than 510.000 ha, dominated by 90% of peat swamp forest (PSF) which is susceptible to several disturbance sources (fires, illegal logging, land encroachment, alien species invasion, etc) and experiencing more deteriorated condition if there is no significant action carried out in managing its resources. Thus, it is important to improve the productivity of this PSF by planting it with native commercial tree species in order to maintain its role both in production and conservation aspects. The main objective of this study was to determine suitable PSF native species to rehabilitate highly degraded PSF in KPHP Tasik Besar Serkap. Two native PSF tree species were used namely Balangeran (Shorea balangeran) and Bintangur (Callophylum soulatri). Seedlings were planted at 4 x 3 meter spacing distance, each species was planted in a 1-ha plot, and thus the planting trial total area was 2 ha with 834 individual trees/species/ha. The survival rates at 6 months and 12 months after planting were 81.77% (682 seedlings/ha) and 58.6% (488 seedlings/ha) respectively for Balangeran, and 12.64% (105 seedlings/ha) and 10.34% (86 seedlings/ha) for Bintangur. The average heights at 6 and 12 months after planting for Balangeran were 111.54 cm (±16.731) and 206.03 cm (± 30.905) respectively, while for Bintangur 60.00 cm (± 12.921) and 72.76 cm (± 11.326) respectively. We also observed physical damage on planted seedlings, namely the occurrence of shoot and twig boring (pest) and seedling mortality caused by herbicide contact when our field staff applied herbicide at the experimental plots to ease the planted seedlings from weeds and other competitors. Borer was only identified in the surviving Balangeran seedlings at 12 months after planting with the intensity of attack of 17% . We did not observe similar case occurring in planted Bintangur. Seedling mortality rates caused by herbicide contact for Balangeran and Bintangur were 3.8% and 3,2% respectively. From the study result, it was concluded that only Balangeran was recommended to be planted for increasing the productivity of PSF in the scheme of commercial stand.

“…The scenarios were assumed to start when the current oil palm cycle has come to an end, and they were drawn up for a time-frame of 30 years (based on the rotation length of oil palm which is around 25 years). The scenarios were derived and/ or adapted from reviews and case studies found in literature (Salleh and van den Berg, 2005;van der Meer and Ibie, 2009;Ismail et al, 2009;Sofiyuddin, 2012;Lim et al, 2012;Giesen, 2013;2015;FAO, 2014;OAF, 2014;MPS, 2016;SIIA, 2017;Graham et al, 2017;Lampela et al, 2017). Differentiating factors like polyculture versus monoculture, and immediate change versus transitioning to a paludiculture system were taken into account when formulating the scenarios.…”

million hectares of land in Malaysia are covered by oil palm plantations, with an export revenue from oil palm reaching more than RM 46 billion in 2017 (MPOB, 2017; Kushairi et al., 2018). As suitable and accessible land has become scarce the cultivation has shifted from the more suitable mineral soils towards peatlands 1 formerly covered by peat forest (Omar et al., 2010). These cultivations on peatlands have rapidly increased since the 1990s, mainly for oil palm and acacia plantations. By 2015, of the total peatland area in Malaysia, which is around 2.5 million hectares, approximately 1.06 million hectares were covered with oil palm plantations

The occurrence of fires has frequently been used to highlight environmental hazards at regional and global scale, and as a proxy for the effectiveness of protected areas. In contrast, the mechanism behind wildfire dynamics in tropical peat land protected areas had been poorly addressed thus far. Our study provides a novel application of assessing fire patterns from a tropical peatland protected area and surrounding landscape. We investigated the importance of both climatic factors (top-down mechanism) and human interventions (bottom-up mechanism) on fire occurrences through analyzing 15-year (2001 -2015) LANDSAT and MODIS images of the Padang Sugihan Wildlife Reserve (PSWR). Fire density along side road and canal construction were analyzed jointly together with the monthly and annual precipitation, and evidences of climatic anomalies. The reserve was effective in limiting fire occurrences from surrounding landscapes only in wet years. We revealed that peat fire patterns in the protected area and the landscape matrix emerged beyond climatic factors, and the distance from canal system could explain the fire occurrences. Our results show that it is essential to address processes at a landscape level, particularly at the surroundings of the reserve, in order to increase the effectiveness of fire protection, including the development of fire-prone classes maps. 2 other causal factors, fires are frequently used as an important indicator to evaluate the 3 effectiveness management of protected areas [2, 3]. A common approach to manage fire 4 in protected areas is applying active fire management or prescribed burning [4-7] which 5 aims to reduce fuel availability for preventing and controlling wildfire [8]. Nowadays, a 6 paradigm shift resulted in managers purposely burning grassland and forests to 7maintain the ecological mechanisms which drive ecosystem dynamics and diversity [7,9]. 8 Anthropogenic and natural factors lead to different patterns of fire occurrences in 9 protected areas across various ecosystems. Fire density was found to be two times 10 higher in non-protected areas than within protected areas in Myanmar [10] and 11 PLOS 1/15Amazonian regions [2]. It has been shown that human intervention influences a 12 protected areas susceptibility to disturbance. At a global scale, forest loss rates in 13 protected areas is associated with high proportions of agricultural land in the country 14 [11]. Managing anthropogenic factors which include fewer road construction, less human 15 impact mechanisms [2] as well as fire-free land management [12] in the reserves has 16 shown their effectiveness in reducing fire-driven deforestation. In contrast to fire 17 occurrences in tropical areas, natural mechanisms caused higher fire density in 18 protected areas than in non-protected areas in West and Central Africa [13]. More fires 19 occurred in 59 percent of the area where deforestation rates dropped between 2000 and 20 2007, since more fuel was available for ignition [12]. Here, controlled ignition and active 21 fire mana...
