Impact of oil palm plantations on herpetofauna species diversity in KGP and CNG, West Kalimantan

Changes in plants diversity occurring the establishment of oil palm plantations, have been considered as the reasons for the changing pattern in community livelihoods. Hence, the values of plants diversity to the local community worth considering. This research was conducted to identify the local communities’ perceptions related to gain and loss of plant species diversity due to the establishment of oil palm plantation. The study was carried out in the indigenous Dayak Villages of Tajok Kayong and Nanga Tayap, West Kalimantan Province of Indonesia in March 2018. Data were collected using field observation and interviews. Our results indicate that the establishment of oil palm plantation have resulted in the gain of 3 plant species and the loss of 8 plant species functional values (medicine and food). Nevertheless, as many as 75.68% of interviewed person stated that the presence of oil palm plantations increased plant diversity, in terms of flowering plants and other non-functional plants. These findings reveals that local community were not affected by the species loss since prior to the plantation’s establishment, their living patterns were already transformed into semi modern and modern living styles in which the people have lower dependence on their surrounding plants.

Timber forests have many functions and play an essential role in human life. This means that the existence of timber forests provides many benefits for human life. Economic development activities actively implemented throughout the province of West Kalimantan have resulted in more and more areas of timber forest and rubber plantation areas being converted into oil palm plantations. The rampant development of oil palm plantations carried out by investors and those carried out independently by each resident, in essence, provides a significant enough job opportunity for the population in each area that continues to grow. Job opportunities created through economic development offer opportunities to every working population to earn income, fulfilling various life needs is mainly directed to fulfilling family nutritional consumption. If the family's nutrition is guaranteed, then the average life span of the population can be longer. In addition to meeting his family's needs, this income can also be used to finance children's education belonging to the school-age group. If the income earned by each family is large enough, then the family should be able to live in prosperity. This means that timber forest and rubber plantation areas privately owned by the community have been converted into oil palm plantations, significantly contributing to the economic growth of districts/cities in West Kalimantan province and improving the community's welfare.

Microhabitats capacity to support insect species diversity and persistence were evaluated implementing solitary parasitoids and predatory insects according to different phases of herbicide and chemical fertilizer applications. Two species of the genus Xanthopimpla (Ichneumonidae) and one species of the genus Pompilus (Pompilidae) showed relationships on vegetation-type microhabitats, notably natural weeds, leguminous cover crops, and the beneficial plant Turnera subulata, while two species of the genus Evania (Evaniidae) showed relationships with chipped oil palm trunks. One species from the genus Odontomachus (Formicidae) as an exclusive predatory ant was related to both chipped oil palm trunks and the beneficial plant T. subulata. Xanthopimpla parasitoids exhibited abundance fluctuations difference around natural weeds during herbicide application phases between three- and six-years old oil palm stands, with decreased and increased abundance patterns of the former and the latter, respectively. 18 years old oil palm stand showed increased abundance patterns only along with the different phases of chemical fertilizer applications. The importance of natural weeds diversity, restrictions of leguminous cover crops, frequency of herbicide applications, and the arrangements between beneficial plants and wood-based microhabitats that benefited insect parasitoids and predators were discussed.

Natural orchids are one of the flora in Mount Poteng which is included of Raya Pasi Nature Reserve located at Singkawang City, West Kalimantan Province. Orchids have economic value for source of income and be beneficial to ecology that needs to be protected. The altitudes and environmental factors strongly affected the presence of orchid species.The research aims to record the diversity of natural orchids species based on the altitudes place in Mount Poteng. The research was conducted on February 28 until March 28, 2020. This research uses survey method. The research sample was taken using double plots method and to determine sample plots locations is conducted by purposive. The total number of the sample plots is 16 plots and each plot measure 20 by 50 meters. Based on the result of research found 19 species of natural orchids that consist of 348 individuals. The results analysis of the diversity index of orchid species in whole of altitudes at Mount Poteng is 1,338 that is included medium range. The highest species diversity index of 1,300 occurred at altitude of 400-500 m asl and the lowest species diversity index at altitude of 700-725 m asl that is 0,594. Orchid species which found in whole of altitudes is Dendrobium crumenatum. Furthermor, there were found the orchid species on certain heights are Cleisostoma scortechinii, Cordiglottis filiformis, Ludisia discolor, and Phalaenopsis pantherina at altitude of 400-500 m asl and species of Bromheadia finlaysoniana and Pomatocalpa latifolia found at altitude of 700-725 m asl.Keywords: altitudes, mount poteng, orchids, species diversity

Plant Stem

A survey of plant species inhabiting oil palm trees was conducted in Zawlpui area of Serchhip district, Mizoram. The study area is a tropical potent agriculture zone, wherein small-scale business of Elaeis guineensis plantation is carried out by several farmers mainly within the gentle sloppy terrain. Oil palm with a rough bark harbors immense inhabitation by a variety plants, that rooted mostly on the debris at leaf base. Species diversity on the plant stem supposedly encourage insects and termites to establish herewith, thus causing harming to the tree. The sample stands within 400 m–800 m altitude were picked randomly. A total of 50 palm tree were accounted and all associated plants on the stem above 30 cm from the ground are all recorded. Species that cannot be identified on the site were pressed and observed at Botany Research lab, Pachhunga University College. The survey documented 38 vascular plant species which include 4 epiphytes and 1 non-vascular species of lichen, 1 bryophyte and 4 fungal species at that time. Invasive Peperomia pellucida and epiphytic pteridophytes Nephrolepis biserrata was found in most of the stand sample; however, Peperomia population decreases with the increasing elevation. Dynamics of inhabitant species diversity also correlate to location of tree. The study also established that diversity of inhabiting species was comparatively high on parts of the stem facing sunlight.
