Abstract

The island of Sumatra harbors a few large ungulates, including the endangered Asian tapir, Tapirus indicus, whose population is believed dwindling due to habitat loss and fragmentations. Recent surveys indicated that the species occurs in a wide range of habitats which are strongly affiliated to natural forests. In Riau Province, Rimbang-Baling Wildlife Reserve is one of the remaining pockets of tapir population. We have conducted a preliminary assessment of tapir population in this reserve using camera traps. We operated 20 camera-traps in 20 systematically grids. From 1,710 effective trap nights, 304 images of tapir with 71 independent images were obtained, which were identified as 14 individuals. Based on the best models developed in DENSITY Program Version 4.4, we estimated that there were 7.60 ± 2.40 (D±SE)tapir individuals/100 km2 in the surveyed area. Our study provided the first density estimate of this endangered speciesin Sumatra using Spatial Explicit Capture-Recapture method. The findings indicate that Rimbang Baling is an important area that should be protected more effectively if the Asian tapirs want to be conserved for the long term.

Abstract

Rama-rama is one of typical macrofauna from the mangrove ecosystem. The existence of this organism can be seen easily from the appearance of mud mounds in the ground surface as a result of bioturbation activity. The purposes of this research were to understand rama-rama species in the coastal area of Bukit Batu and the characteristic of bioturbation conducted by this organism and also to obtain the valuation of important impact of this activity to its environment. This research had been conducted from September to November 2013 in Bukit Batu and Tanjung Leban villages. Observation was conducted in four line transects, 1100 m length, from the edge of the water during the lowest tide. There were 10 transects (10 m x 10 m) placed along the line (100 m interval). The diameter and height of mud mounds, diameter of the hole, soil bulk density and the ability of rama-rama in carrying the soil / day were observed. Information on impact of the presence of the rama-rama on the social condition of people was obtained by interviewing people living around the coast. The results show that there were 2 species of Thalassina, namely T. anomala and T. spinosa. Rama-rama bioturbation activities were influenced by its body size and soil bulk density. The average of soil carrying capacity of each rama-rama was 740 cm3/mound/day. Therefore, with the average density of mound was 3,9 mound/m2, the soil carried was around 2900 cm3 /m2/ day or 11.000 m3/ha. It can be concluded that the soil carrying capacity of the rama-rama is potential to affect the coastal area environment.

Abstract

Since 2006, scientists consider Sundaland clouded leopards Neofelis diardi as a unique species, different from the mainland Asia species N. nebulosa. The species is categorized as vulnerable in the IUCN Red List and is only found in Borneo and Sumatra islands. Massive deforestation in Sumatra is believed to increase the endangerment of this species. This study aimed to estimate the density of this species and assess its conservation status in Central Sumatra, especially in Rimbang Baling Wildlife Reserve. In this study we present the density estimation which was calculated with spatial capture-recapture models using photographic data resulted from a tiger-focused camera-trapping study. This study used 40 cameras at 20 stations, with accumulation of 1.710 effective camera trap days, resulted 32 independent images of 8 individually identifiable of clouded leopards. They consisted of 5 males, 1 female and 2 could not be determined. The density of clouded leopard in this study was 2,80±1,11 (D±SE) individual/100 km2. This density is considered as relative lower than the estimates of Sundaland clouded leopard densities documented in some other areas in Borneo and Sumatra. This suggests that Rimbang Baling can be managed to support a healthy and perhaps viable population of Sundaland clouded leopards in Central Sumatra.

Abstract

Mud lobsters (Thalassina) are one of the most common macrofauna in mangrove ecosystems, especially in the Indo-Pacific region. The presence of this fauna is typically marked by mud mounds that are hardly overseen in its habitats, as a result of its bioturbation activities. This study, which focused on Bukit Batu coastal area in Riau Province, aimed to identify the occurring species in the area, describe the distribution and abundance patterns along the sea-inland gradient, and identify critical factors affecting the patterns. Observations were carried out in the focal area from September to November 2013 along four 1100 m-long transects, on each of which 10 quadratic plots of 10 m x 10 m were established in 100-m interval. The observed parameters were the characteristics of vegetation cover, soil BD, groundwater level, groundwater salinity and pH, beside number of “active” mounds. At least two species of mud lobsters were countered, T. anomala and T. spinosa. Mud lobster mounds were totally absent at a distance of 0 and 100 m from lowest-tide line, while most abundant at a distance of 200 m, with 9.4 mounds/m2. The abundance decreased sharply following the increasing distance toward inland, which was down to 0.09 mounds/m2 at 1100 m. Mounds were more evenly distributed toward the sea, while increasingly random as their density decreased. Groundwater salinity was the most critical affecting mound distribution and abundance.

Abstract

Meliponiculture emerged at Tanjung Sari, a village in Kepulauan Meranti Regency, Riau Province, in 2016 and has been growing thereafter. According to our observations there were at least three main obstacles faced by colony owners at this village, i.e. colony loss, low honey production, and marketing-related issues. We attempted to address these issues through a participatory program involving colony owners of the village. Colony loss had been mainly caused by swarming and mortality and was believed to have been triggered by inappropriate conditions of the maintenance (such as too much exposure to the sun and rain as well as unrepelled diturbances by other animals. Such conditions had also been associated with low honey production. Therefore we encouraged villagers to improve the conditions by providing supporter and roof for their colonies. In regard with marketing issues, we encouraged villagers to establish a honey cooperative under BUMDES, which should regulate honey price, absorb the produced honey, and also handle its marketing to outer counterparts. In addition, the cooperative should facilitate communications between members and information disemination, and mediate negotiation with potential buyers. The benefits gained by participants were: (1) the improvement of technical knowledge of colony maintenance; (2) the improvement of colony maintenance quality that would reduce risk of colony loss; and (3) the establishment of a cooperative that would be a body that would facilitate the necessities previously mentioned. The present paper describes the processes and results in details.

Abstract

In 2016, a number of villagers in Kampung Rawa Mekar Jaya founded a ”pokdarwis,” a group of villagers who were eager to manage a remnant of mangrove forest for ecotourism, which is situated on the bank of Rawa River. The establishment of touristic infrastructure and the continuing promotion have attracted visitors from other localities. However, the increasing number of visitors has caused damages of the existing infrastructure. During 2018-2019, Riau University’s Institute for Researches and Community Services has launched a Village Foster Program in Kampung Rawa Mekar Jaya with the objective of improving local community’s capability of managing the mangrove forest remnant, particularly by integrating ecotourism with stingless beekeeping for honey production. Some activities that have been done included: (a) mapping of mangrove forest; (b) mangrove tree naming and labelling; (c) training for mangrove eco-guiding; (d) establishment of stingless beekeeping site with enriched food plants. Members of pokdarwis showed enthusiasm by joining these activities since they were aware of the importance of these activities. However, it was the leader of the pokdarwis who has played a more important role as a motivator with remarkable attitudes, such as being honest, dependable and highly praising equality.
