High Conservation Value Areas (HCVA) in palm oil plantation is one of the efforts to reduce the negative impoct of oil palm plantations on biodiversity. The purpose of this study was to to identify bird species in dffirent types of habitats in the conserration area of oil palm plantations, calculate and compare the diversity of bird species and how is the relations with vegetation as habitat componen\ the study location at PT. MSM, Wilmar Plantation Central Kalimantan. The results showed the diversity value of birds and vegetation hos a positive relationship. Forested habitat v,ith heterogeneous vegetation presenting a higher value of diversity bird species than homogeneous vegetation hobitat. The highest diversity of bird species is the habitot of swampforests (H'3,70) lowland forest (H'3,69), heath forest (H'3,59) and the lowest is the habitat of palm plantatioru (H' 2,60).

This work presents results of two years collecting efforts within the project “The role of the alpine karst area in Bulgaria as reservoir of species diversity”. It summarizes distribution data of 44 terrestrial gastropods from the Bulgarian part of Alibotush Mts. Twenty-seven species are newly recorded from the Alibotush Mts., 13 were confirmed, while 4 species, previously known from the literature, were not found. In the gastropod fauna of Alibotush Mts. predominate species from Mediterranean zoogeographic complex. A large part of them is endemic species, and this demonstrates the high conservation value of large limestone areas in respect of terrestrial gastropods.

Tropical Peatlands

The characteristics of tropical peatlands are still able to form a high diversity of plants. Conversion of tropical peatlands affects the composition of plants. The aim of this study was to find out effect of land use changes to the composition and diversity of plants in the Peat Hydrological Unit (PHU) Mendahara - Batanghari River. The research was conducted in three land use categories, namely secondary forest, coffee plantation, and oil palm plantation (subdivided into oil palm plantation 1 and oil palm plantation 2). In each study location, sample lane 20 m x 200 m were made. Overall, we found 77 species of plants. The results showed   number of plant species decreased due to changes of land use. There are 51 - 53 species of plants in secondary forest areas (out of a total of 58 species) that are not found in oil palm and coffee plantations areas. Differences in composition were also shown in the low value of community similarity (<50%). In the oil palm and coffee plantation areas, plant communities tend to be dominated by pioneer plants such as Melicope lunu-ankenda, Coffea liberica, Macaranga triloba, and Melastoma malabathricum. Secondary forest was dominated by plants species that characterize peatlands such as Tetramerista glabra, Parastemon urophyllus, Knema percoriacea, Litsea costalis var. nidularis and Madhuca motleyana. Changes in land use also reduce the level of diversity (H 'and R) at various levels of growth. Whereas in the oil palm and coffee plantation areas tend to form uniform stands (indicated through index E which describes the abundance distribution in community and index C which describes the dominance of species). Generally, the distribution pattern of plants is clumped. Uniform distribution was found in K. percoriacea and L. costalis var. nidularis. Keywords: land use changes, peatland characteristics, plant composition, plant diversity

The expansion of oil palm plantations in Indonesia is often blamed as the drivers of natural resource destruction and decrease the tropical biodiversity. Herpetofauna is one of biodiversity on oil palm plantation, but information about its species diversity is still limited. This research was aims to reveal the variation of diversity of Herpetofauna on oil palm landscape in central Borneo. Field inventory was conducted on seven types of land cover i.e. young oil palm, mature oil palm, old oil palm, High Conservation Value area, secondary forest, shrubs, and smallholder plantation. We used Visual Encounter Method to invent Herpetofauna spesies on all land cover type. This study reveal that the diversity of Herpetofauna species in PT BLP varies by land cover type. The land cover types of HCV and Secondary Forest have the largest number of species (12 species). Secondary Forest is the type of land cover with the highest abundance among other types of land cover, followed by old oil palm plantations. The oil palm plantations lanscape with different type of land cover can be part of the habitat for several Herpetofauna species and managed for sustainable oilpalm scheme.

Sloping Land

The slope of land in oil palm plantation areas is the one of the primary causes of low soil water content due to low rates of soil infiltration. Biomulch is one of the conservation methods that can be used to cover and shield the soil from weeds, prevent soil erosion, and increase the rate of soil infiltration. Arachis pintoi is a perennial, stoloniferous legume crop that has potentials to be used as biomulch. The objective of the research was to study the role of Arachis pintoi in increasing the rate of soil infiltration on a sloping land of oil palm plantation. The research was conducted on the slope land (22.8%) of the Bukit Kemuning Farmer Group, Mersam, Batanghari, Jambi, Indonesia (01036'21", 102057'11") from September 2017 to March 2018. The environmental design used in this study was a one-factor randomized block design (RBD) with five ground cover treatments, i.e. natural vegetation, Arachis pintoi, Centrosema pubescens, Pueraria javanica and Calopogonium mucunoides. The results showed that the average growth rate of A. pintoi was 2.47 cm per week, which was lower than the growth of other treatments. The root length of A. pintoi was 50.36 cm at 20 weeks after planting. A. pintoi can be used as biomulch; sloping land planted with A. pintoi had an infiltration rate of  49.30 cm per hour at 20 week after planting, i.e. an increase of 32.47% compared to the infiltration rate with the natural vegetation.Keywords: land cover crop, Centrosema pubescens, Pueraria javanica, Calopogonium mucunoides
