Analisis Potensi Habitat dan Koridor Harimau Sumatera di Kawasan Hutan Lindung Bukit Batabuh, Kabupaten Kuantan Singingi, Provinsi Riau

ABSTRAK Pulau Sumatera adalah surga bagi keanekaragaman hayati, tapi surga ini sedang terancam oleh berbagai tekanan dari aktivitas manusia dari konversi hutan, pembukaan lahan yang tidak terkendali untuk perkebunan, perambahan dan perburuan liar. Saat ini, hutan alam di Sumatera berada di bawah tekanan kuat yang mempengaruhi pada kondisi ekosistem dan keanekaragaman hayati di dalamnya. Situasi yang sama juga terjadi di pulau besar lainnya di Indonesia, yaitu Papua, Kalimantan, Sulawesi, Sumatera, dan Jawa. Penelitian ini dilakukan dengan Penginderaan Jauh dan Sistem Informasi Geografis. Teknologi Penginderaan Jauh digunakan untuk mengidentifikasi tutupan lahan dan bentang alam berdasarkan genesis. Sementara teknologi GIS digunakan untuk menilai kesesuaian habitat harimau sumatera dan untuk menentukan potensi daerah untuk pengembangan koridor habitat untuk mempertahankan konektivitas antara dua blok hutan dipisahkan oleh jalan di daerah. Lokasi penelitian adalah Bukit Batabuh Hutan Lindung. Hasil penelitian menegaskan bahwa daerah penelitian ini cocok untuk mempertimbangkan sebagai habitat Harimau Sumatera, tetapi berfungsi sebagai habitat koridor saja dan tidak dianggap sebagai habitat inti, karena wilayahnya yang hanya mampu menampung kurang dari dua harimau. Namun demikian, mengingat lokasi strategis daerah ini sebagai hubungan antara dua kawasan lindung yaitu Rimbang Baling dan Taman Nasional Bukit Tigapuluh, wilayah ini sangat penting untuk dilindungi. Degradasi kesesuaian habitat terjadi pada kisaran 2002 - 2013 dengan indikasi pengurangan kawasan hutan alam yang berdampak langsung pada kondisi ekosistem di daerah. Keberadaan jalan memisahkan blok hutan Bukit Batabuh di daerah memberikan kontribusi yang terhadap tekanan tinggi kerusakan lingkungan. Lokasi potensial untuk membangun koridor habitat adalah lokasi di mana masih ada tutupan vegetasi yang relatif padat. Hutan alam di sepanjang jalan yang memisahkan hutan Bukit Batabuh telah hilang, namun tetapi pohon karet di daerah dapat digunakan sebagai daerah vegetasi karena struktur kanopi mirip dengan pohon di hutan alam. Lokasi dekat dengan jembatan juga menjadi pertimbangan yang baik karena dapat berpotensi digunakan oleh hewan untuk lewat. ABSTRACT Sumatera Island is a paradise of biodiversity, but it is being threatened by pressure human activity in forest conversion, clearing of land for plantations, encroachment and poaching. Recently, the natural forests in Sumatera are under pressure affecting in ecosystem conditions and biodiversity in it. That same situation is also occured in other major island, namely Papua, Kalimantan, Sulawesi, Sumatera, and Java. This research was conducted by Remote Sensing and Geographic Information Systems. Remote Sensing Technology is used for indentifiying  landcover and landscape based on genesis. While GIS technology is used to assess the suitability of Sumatran tiger habitat and to determine a potential areas for development of habitat corridors to maintain connectivity between two forest blocks which separated by road in that area. The research location is Forest Preserve Batabuh Hill. The results have confirmed that the area is suitable for consideration as tiger habitat, but it has function for habitat corridors only and not regarded as a core habitat, because this area be able to accomodate fewer than two tigers. However, considering the location of strategic area as relationship between two protected areas that Rimbang Baling and Bukit Tigapuluh National Park, it has very important to be protected. Degradation of habitat suitability was occured of 2002 - 2013 with indication of reduction in natural forest areas that directly impact on ecosystem condition in the area. The existence of separate forest blocks Batabuh Hill in roads is giving contributed on  high pressure environmental damage. The potential area to establish habitat corridors is located in area with covered of relatively dense vegetation. Natural forests in along road is separating Forest Hill  Batabuh already lost, but the rubber trees in that area can be used as vegetation area because canopy structure similar a tree in natural forests. The location which near in bridge is also into consideration because could be potential for animals to pass

Developing ecosystem service indicators: experiences and lessons learned from sub-global assessments and other initiatives

People depend upon ecosystems to supply a range of services necessary for their survival and well-being. Ecosystem service indicators are critical for knowing whether or not these essential services are being maintained and used in a sustainable manner, thus enabling policy makers to identify the policies and other interventions needed to better manage them. As a result, ecosystem service indicators are of increasing interest and importance to governmental and inter-governmental processes, including amongst others the Convention on Biological Diversity (CBD) and the Aichi Targets contained within its strategic plan for 2011-2020, as well as the emerging Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES). Despite this growing demand, assessing ecosystem service status and trends and developing robust indicators is o!en hindered by a lack of information and data, resulting in few available indicators. In response, the United Nations Environment Programme World Conservation Monitoring Centre (UNEP-WCMC), together with a wide range of international partners and supported by the Swedish International Biodiversity Programme (SwedBio)*, undertook a project to take stock of the key lessons that have been learnt in developing and using ecosystem service indicators in a range of assessment contexts. The project examined the methodologies, metrics and data sources employed in delivering ecosystem service indicators, so as to inform future indicator development. This report presents the principal results of this project

IDENTIFICATION OF CONSERVATION PRIORITY LOCATION IN INDONESIA BASED ON LAND-SEA CONNECTIVITY

The environment quality around those rivers and canals will affect the health of the coastal ecosystem and biota living in it. Empirically, there is an ecological connection between ecosystem in coastal areas and between coastal areas to the mainland and the high seas. Therefore, marine spatial planning should consider any change on landscape upstream. The aim of this study was to define new locations which have high conservation value based on connectivity between terrestrial and marine. The method used in this study was spatial analysis using systematic conservation planning approach with Marxan as the decision support tool. Marxan works based on scenarios developed by spatial planner. This study was using two primary scenarios: first, consider the existing protected areas; second did not consider the existing protected areas (PAs) to identify the gaps between new priority locations and the existing PAs. The data used in this study were basic spatial data, ecological data, and biodiversity data from various sources. The study area were all islands of Indonesia, devided into seven clusters. Based on those two scenarios, the result of the study shows that there are 108 locations in Indonesia which identified as areas which have high conservation value and also hold potential land-sea connection at once, inside and outside existing protected areas. Based on this study, if in the future the stakeholder have plans to do intervention in those areas primary in conservation field, those identified locations could be considered as new areas.
