On the dry region of Wonogiri Regency and Pacitan Regency, in the Central Java and East Java Provinces border of Indonesia, there is a potential group of plant which is still disguise from the researchers attention. These wild edible tuberous plant, were actually have potential source of carbohydrate as an alternative to rice or corn inside the forest system or agro-forestry system. Their minimum maintenance, adaptability to drought and shading make them a potential plant as the staple food for the local people residing inside or in the forests buffer zone. Wild taro (Aracaceae family) existence in the forest system or agro-forestry might increase the economic sustainability of forest. Using a Randomized block design method on the 5 plots sample located on the Northern slope of Wonogiri dry-land, the density and distribution type of wild taro and taro-like plants were surveyed. There were six genus of wild tuberous plant with 12 identified species and several endemic species identified. Xantosoma sp has the highest population, and generally the aroid plants have clumped distribution. Current situation of economical importance of other commodity and relationship with human agricultural activities may vary the distribution of Taro.Keywords: Edible wild taro, distribution, altitude

The vertical and spatial variations in the abundance of canopy insects werecompared between secondary forests in Kanazawa, Japan and Trawas, East Java, Indonesia. The patterns of canopy insect abundance and composition change with layer and site weredetermined. The study in Central Japan was conducted at a mosaic habitat of a suburban forest in Kanazawa, Central Japan. Two patches were selected for sampling: a young deciduous patch and a mixed vegetation patch. Canopy insects were collected 12 times from June to October 2003. Another study site is located in Trawas, East Java, Indonesia. Insect sampling was performed at three sites along a gradient of anthropogenic disturbances, from a less-disturbed site in an upper hilly area, through a partly-disturbed site, to a highly-disturbed site. Samplings were performed by using window traps, suspended in the canopy layer and in the understory layer. This study revealed that canopy insect communities vary among canopy layers and sites. However, this study did not indicate consistent insect stratification between regions. Data in temperate region showed that the abundance of canopy insects is greater in the canopy layer than in the understory layer. In tropical region, the abundance of canopy insects between understory and canopy layer was similar. The young deciduous patch consisted of more individuals of canopy insects than in the mixed vegetation patch. Our study in tropical region demonstrated significant effects of disturbance on the abundance and family richness of canopy insects. The overall insect abundances and richness differed among sites.Keywords: Anthropogenic disturbance; canopy insect community; secondary forest; temperate and tropical region; window trap

Global attention to the global warming reduction has invite numerous strategy implemented with the objectives is mitigating greenhouse gasses emission which threats to the future of living in biosphere. Essentially, absorbing CO2 from atmosphere and sequestering in terrestrial ecosystem is one of the significant strategy. While in developing countries it is become essential, support for forest conservation, afforestation and effort to increase terrestrial ability to capture and storage carbon is poor. Ecotourism offer potential key to solved such problems by promoting ecolodge as a sustainable tourism accomodations. This paper aims to explore the potential of ecotourism sector to alleviate global warming and establishing framework for ecolodge planning and development in tropical developing countries. This paper highlight the significant of ecolodge attraction and development management to meet proper carbon capture and sequestration mechanism. The attraction management and developing programs ultimately able to increase plants biomass while accommodation able to practicing energy efficient and optimizing reuse and recycle approach. It will become the potential solution for reducing greenhouse gas emissions and create clean development strategy.

In the biological science, invertebrate (especially insect) diversity is relatively well known. Yet, little study about their interaction with specific land use or specific system function. With the rapid changes of landscape, biodiversity is also changes in response to human impact; due to each organism have the specific interaction with certain environment. In this research, the assessment of insect order in the different landscape types was conducted using several method of trapping to understand the specific pattern of insect which are inhabited the landscape. The objectives of this research were monitored the Insect diversity, its ecological importance to agro-forestry ecosystem, and compare it with other forest type in this area. Another objective was determined the insect characteristic as the indicator of environmental quality on each land-use system (forest, agroforestry, plantation and monoculture). Monoculture agriculture has the largest number of Lepidoptera and Hemiptera order (herbivore insect dominated) while in agro-forest system has the largest number of Diptera and coleoptera order. Protected forest, plantation forest and agro-forestry showed the similar index number which shows the similar ecological services for the insect as their habitat. However, in the monoculture agriculture, there was an unbalance insect composition and high dominance.Keywords: landscape, biodiversity, environment indicator index

This research focuses on investigating West Kalimantan’s traditional landscapes, shifting cultivation pattern, and comparing the forest dependency of several ethnic groups. After conducting remote sensing and geographical information system techniques based on the satellite images LANDSAT-TM in West Kalimantan from 1996 to 2006, the decrease of primary dry tropical forest from 36.4% to 15.9% and a little increase of agriculture land from 44.8% to 45.1% were detected. West Kalimantan’s traditional landscape is a combination of primary forest, shifting dry rice-field, rubber plantation, fruits garden and home garden, meanwhile new landscape managed by migrants mainly consist of permanent wet land rice-field, dry land rice, and crop fields. The decreasing forest area forces the native people to shorten the shifting cultivation cycle or to turn to permanent agriculture with the low yield. This situation is the result in the more primary forest clearing for agriculture usage by native people and migrants. It is clear that the traditional landscape of West Kalimantan is particularly dependent upon its most vital element, the forest. Yet, traditional landscape representing the regeneration cycle of forest in West Kalimantan was constrained by changes in managed and modern landscape.
