“…However, in trying to restore and maintain the long-term sustainability of peatlands, the Indonesian government has been confronted with two major issues: frequent fire that prevents effective revegetation and ensuring sustainable livelihoods for those people who depend on access to peatlands. Repeated peat fires cause peatland degradation due to loss of peat soil as well as changes in its chemical and physical properties [19,20]. In addition, the choice of prospective species on peatland is limited [19] due to low fertility, high acidity, and poor drainage [10].…”

Peatlands support the daily needs of people in many villages in Indonesia, including in Central Kalimantan Province. They provide the natural resources to enable fisheries, agriculture, plantations, and forestry. However, peatland utilization comes with various challenges, including fire, soil acidity, inundation, low fertility, and limited choice of suitable species. Many of the current uses of peatland can result in its degradation, oxidation, and increased risk of peat fire. Avoiding further environmental degradation will require the development of new technology that allows the community to both earn a livelihood and protect the peatland. In this study we assessed a range of technologies applied by 14 farmers at Tumbang Nusa village, Central Kalimantan province, in managing degraded peatlands in their home yard for agricultural business. The study shows that for endemic peatland species, good success can be achieved if they are planted directly. However, for species endemic to mineral land, there are four technologies applied by farmers in managing degraded peatland. The choice of technologies is influenced by their economic capacity/cash flow flexibility and their understanding of peatlands. Technologies intended to adapt to land inundation include the use of polybags, development of raised beds, and making peat mounds with mineral soil in the centre. Technologies to address the acidity and soil fertility include amelioration with dolomite lime and fertilizer. The use of polybags filled with peat soil is the easiest technology to adopt and can be conducted by all family members. However, a farmer’s choice of technology needs to always consider the potential environmental impacts in addition to increasing soil fertility so that peat conservation is maintained.

“…Disturbed forest occurred in the area of around 2.4 million ha. Forest restoration strategies [27,59] should be created by integrating disaster risk reduction programs [60,61], adaptation and mitigation procedures of climate change [62][63][64], and landscape management plans. These strategies are the new opportunities and difficulties presented for mitigating climate change.…”

Restoring deforested and degraded forests is mandatory to guarantee the future of tropical forests. In this study, we formulated silvicultural strategies for restoring tropical forest ecosystems using geospatial approaches to detect deforested and degraded forests based on landscape circumstances. Depending on the overlaid map of the current land cover and its land status, we categorized our forest restoration activity map into three main groups: reforestation, forest rehabilitation, and none. Based on the forest vulnerability, as evidenced by slope and erosion risk, we also allocated the ranks of restoration location into three priorities: first, second, and third. We believe that geospatial modeling maps can assist decision-makers in selecting locations and the most important goals for reforestation in order to reduce greenhouse gas (GHG) emissions in land-based sectors. In order to exactly convey the geospatial data of forest at more detailed landscape scales, such as sub-district and village levels, as well as forest management units, these study need to be enhanced using high-resolution satellite or aerial imageries.

“…The selection of sampling locations was based on the presence of macrofungal fruiting bodies at the research site. The study site had previously undergone adjustments in groundwater levels, as described in previous studies (Astiani et al 2020). Specifically, there were four levels of groundwater: 30 cm, 40 cm, 50 cm, and 60 cm from the soil surface.…”

“…In peatlands, the water level of the peat has a significant impact on the life of organisms, including fungi (Astiani et al 2018;Astiani et al 2019). The research location chosen for this study is an area where the peat water level has been regulated (Astiani et al 2020). Specially, the research focused on the macrofungi in small-holder oil palm plantations that are managed by the local community and planted peatland in Kampung Baru Village, Kubu Subdistrict, Kubu Raya District, West Kalimantan, Indonesia.…”

Abstract. Ekyastuti W, Astiani D, Ekamawanti HA, Jamiat. 2023. Macrofungal diversity in small-holder oil palm plantations on tropical peatlands. Biodiversitas 24: 3454-3461. Mushrooms play an important role in ecosystems and human life. They can be found in various places including in oil palm plantations. The aim of this study was to survey and identify the population of macroscopic mushrooms or macrofungi in small-holder oil palm plantations on tropical peatlands in Kampung Baru Village, Kubu Raya District, West Kalimantan, Indonesia using the field survey method. In the research area, a dam has been constructed to regulate the water level at 30 cm, 40 cm, 50 cm, and 60 cm from the surface. Sampling was carried out in these four conditions. The study revealed the presence of 34 species of macrofungi belonging to the Basidiomycota. A groundwater level ranging from 40-60 cm from the surface was identified as favorable for macrofungal growth. Meanwhile, a groundwater level of 30 cm from the surface was found to be unsuitable for macrofungal growth in the peatlands. The level of macrofungal species diversity in small-holder oil palm plantations on the peatlands was determined to be moderate.
