The expansion of oil palm plantation has been claimed as a major driver of biodiversity loss in the tropics, including birds. To date, only a few studies have been conducted to document the variation of bird diversity in different land cover within oil palm plantation. Therefore, it is necessary to conduct the research to investigate the variation of bird diversity. The objective of this study to identify the diversity of bird in different land cover within oil palm plantation. The observation of bird diversity was done in young stand of oil palm, old stand of oil palm, smallholder oil palm and in secondary forest as high stock carbon as natural reference before converting in to oil palm. The survey was done in August 2017 in Central Kalimantan, Indonesia. Data of bird species were recorded by direct observation using transect method. To calculate the diversity value of birds at different land cover, we used Margalef Index (Dmg) and Comunity similarity (IS). The result showed that the number of species and species diversity was highest at high carbon stock area which the number of species was 25 species and Margalef Index was 5.99. The young stand of oil palm have the highest evenness index (0.93), while the highest similarity index was observed in old stand of oil palm and in smallholder oil palm. Our study concludes that the existence of high carbon stock areas within oil palm plantation had a positive influence in increasing bird diversity. From a conservation perspective, retaining of natural habitat such as high carbon stock within oil palm plantation is one strategy to conserve biodiversity.

Asystasia Gangetica

Asystasia gangetica (L.) T. Anderson is a weed commonly found on oil palm plantations and can be used as cover crop for mature oil palm plantations due to its tolerance to shading. The use of cover crop is  a soil conservation technique to support sustainable availability of soil nutrients by reducing erosion and nutrients loss, particularly during the rainy seasons. This research aims to determine the roles of A. gangetica as cover crop for measures against erosion and nutrients loss in mature oil palm plantation. This research was conducted in oil palm plantation, Unit Rejosari, PT Perkebunan Nusantara (PTPN) VII, District of Natar, South Lampung Regency from August 2014 to April 2015. The research used split block design in randomized complete block design with two factors and six replications. The main plots were ridge terrace, namely with and without ridge terrace. The sub plots were cover crops, namely with and without cover crops A. gangetica. The results show that using A. gangetica as cover crops in mature oil palm plantations effectively minimized erosion and loss of organic C, N, P, and K by 95.7%, 93.4%, 96.0%, and 90.0 %, respectively. The use of cover crop became more effective when combined with ridge terrace and reduced erosion by 94.1% and loss of organic C, N, P and K by 99.1%, 99.2%, 90.0% and 98.5%, respectively.

The Impact

Currently the expansion of oil palm is increasing, which at the same time creates a lot of negative responses related to environmental impacts, biodiversity loss, including birds and butterflies species diversity. Nowadays our understanding of the impacts of oil palm plantations is still based on the claim that oil palm plantations are established on primary forest land. The study aimed to estimate the impact of land cover changes, loss of biodiversity, and possible cohabitation between birds and butterflies based on baseline land type before oil palm plantation. The research was conducted at PT Tempirai Palm Resources, to be precise, in the baseline area (shrubs) and plantation areas planted with oil palm using direct and indirect observation methods. Based on research, it was known that land conversion to oil palm plantations caused changes in the number of species, and the diversity of birds and butterflies. The number of bird species in the baseline area was higher (S = 22 species, H ‘= 2.51) than in the plantation area. The number of butterfly species in the baseline area was less (0 species) than in the oil palm plantation area (5 species, H ‘= 1.56, Dmg = 2.23). In general, the increase in bird species’ biodiversity was higher (59.09%) compared to the loss. In contrast, the butterfly species was not lost. A cohabitation also occurred between birds and butterflies at the site. The study concluded that oil palm plantation not only have a negative impact but also a positive impact for biodiversity especially for bird and butterfly.­­­­

Abstract. Increasing global demand of vegetable oils and biofuels results in significant oil palm expansion in southeastern Asia, predominately in Malaysia and Indonesia. The land conversion to oil palm plantations has posed risks to deforestation (50 % of the oil palm was taken from forest during 1990–2005; Koh and Wilcove, 2008), loss of biodiversity and greenhouse gas emission over the past decades. Quantifying the consequences of oil palm expansion requires fine-scale and frequently updated datasets of land cover dynamics. Previous studies focused on total changes for a multi-year interval without identifying the exact time of conversion, causing uncertainty in the timing of carbon emission estimates from land cover change. Using Advanced Land Observing Satellite (ALOS) Phased Array type L-band Synthetic Aperture Radar (PALSAR), ALOS-2 PALSAR-2 and Moderate Resolution Imaging Spectroradiometer (MODIS) datasets, we produced an annual oil palm area dataset (AOPD) at 100 m resolution in Malaysia and Indonesia from 2001 to 2016. We first mapped the oil palm extent using PALSAR and PALSAR-2 data for 2007–2010 and 2015–2016 and then applied a disturbance and recovery algorithm (Breaks For Additive Season and Trend – BFAST) to detect land cover change time points using MODIS data during the years without PALSAR data (2011–2014 and 2001–2006). The new oil palm land cover maps are assessed to have an accuracy of 86.61 % in the mapping step (2007–2010 and 2015–2016). During the intervening years when MODIS data are used, 75.74 % of the detected change time matched the timing of actual conversion using Google Earth and Landsat images. The AOPD revealed spatiotemporal oil palm dynamics every year and shows that plantations expanded from 2.59 to 6.39×106 ha and from 3.00 to 12.66×106 ha in Malaysia and Indonesia, respectively (i.e. a net increase of 146.60 % and 322.46 %) between 2001 and 2016. The higher trends from our dataset are consistent with those from the national inventories, with limited annual average difference in Malaysia (0.2×106 ha) and Indonesia (−0.17×106 ha). We highlight the capability of combining multiple-resolution radar and optical satellite datasets in annual plantation mapping to a large extent by using image classification and statistical boundary-based change detection to achieve long time series. The consistent characterization of oil palm dynamics can be further used in downstream applications. The annual oil palm plantation maps from 2001 to 2016 at 100 m resolution are published in the Tagged Image File Format with georeferencing information (GeoTIFF) at https://doi.org/10.5281/zenodo.3467071 (Xu et al., 2019).

Fluctuation of quantity and quality of forage for ruminant animal is a problem of forage availability in Indonesia. Cover crop under oil palm plantation is potential sources of forage for ruminants but it has not been used effectively. This study was conducted to evaluate nutrients quality and estimated energy available of cover crop in dry season in Pelalawan regency, Riau. Seven years old oil palm plantation was plotted by randomized destructive sampling method. Nutrients composition include proximate, modified van soest fraction and protein association with cell wall (NDICP or ADICP) were analyzed for nutrient quality of cover crop. In vitro true dry matter digestibility (IVTDMD) and estimated energy available in cover crop were calculated from in vitro batch culture daisyII Ankom method. The result showed that cover crop is fresh forage energy feed because it contains more than 40% BK of TDN. Limited nutrient quality of cover crop is high contains of Lignin (22.4%BK). Value of IVTDMD of cover crop is 568.41 g/Kg DM with NDF digestibility 21.05% DM. In conclusion, cover crop under 7 years old oil palm plantation had enough nutrients quality for ruminant but it would be better for complete the data in wet season.Fluktuasi jumlah dan kualitas pakan hijauan untuk ternak ruminanasia adalah salah satu permasalahan penyediaannya di Indonesia. Covercrop kebun sawit merupakan sumber potensial pakan hijauan ternak ruminansia tetapi belum dimanfaatakan secara efektif. Studi ini dilakukan untuk mengevaluasi kualitas nutrisi dan ketersediaan energy dalam pakan cover crop kebun sawit pada musim kemarau di kabupaten Pelalawan, Riau. Metode yang digunakan adalah destructive sampling method secara acak. Komposisi nutrisi proksimat, fraksi serat van soest termodifikasi, dan kandungan protein yang terasosiasi dalam dinding sel tanaman (NDICP atau ADICP) di analisis sebagai parameter kualitas nutrisi covercrop. Nilai kecernaan nyata bahan kering/ in vitro true dry matter digestibility (IVTDMD) dan estimasi energi yang tersedia didalam covercrop di hitung dari inkubasi covercrop dalam incubator DaisyII teknologi Ankom selama 30 jam. Hasil evaluasi menunjukkan bahwa cover crop termasuk dalam pakan hijauan segar sumber energi karena kandungan TDN lebih dari 40%. Pembatas nutrisi pada cover crop adalah kandungan lignin yang besar (22.4% BK). Nilai IVTDMD dan kecernaan NDF cover crop sebesar 568.41 g/Kg BK dan 21.05% Kesimpulannya adalah cover crop kebun sawit umur 7 tahun mempunyai potensi sebagai pakan hijauan ruminansia dengan kualitas nutrisi yang baik tetapi juga memerlukan data kualitas nutrisinya pada musim hujan.Keywords: Nutrient quality, In vitro true dry matter digestibility (IVTDMD), cover crop, oil palm plantation, ruminants.
