Merapi Volcano National Park (MVNP) is susceptible to volcanic hazard since it is located around Merapivolcano, especially pyroclastic flow. Carbon sequestration in the national park is becoming a priority of forest developmentas stipulated in Government Regulation Number 28 Year 2011 and Number 49 Year 2011. This study aims to knowthe effect of pyroclastic event to carbon stock in MVNP. In this study the natural carbon rate recovery in MVNP wasestimated to determine the growth rate of natural carbon recovery in MVNP. To estimate carbon stock change in MVNP,2006 QuickBird and 2011 GeoEye satellite imageries were used. Object based image segmentation of high resolutionsatellites imagery could recognize physical dimensions of individual trees such as crown projection area (CPA). In thisstudy, carbon stock was derived using allometric equation based on measured diameter at breast height (DBH) in thefield. A model was developed to estimate carbon stock based on DBH estimation in the field and segmented CPA fromthe image. Based on the segmentation process, the model of CPA and Carbon in MVNP was developed. The F scorewhich indicate the accuracy of segmentation of needle leaf and broadleaved of 2011 GeoEye were 0.68 and 0.54 respectively.Logarithmic model which has 6.37 % error was used to estimate broadleaved carbon stock while quadratic modelwhich has 10.31 % error was used to estimate Pine tree carbon stock in MVNP.

Forests play an important role in global carbon cycling, since they hold a large pool of carbon as well as potential carbon sinks and sources to the atmosphere. Accurate estimation of forest biomass is required for greenhouse gas inventories and terrestrial carbon accounting. The information on biomass is essential to assess the total and the annual capacity of forest vigor. Estimation of aboveground biomass is necessary for studying productivity, carbon cycles, nutrient allocation, and fuel accumulation in terrestrial ecosystem. The possibility that above ground forest biomass might be determined from space is a promising alternative to ground-based methods. Remote sensing has opened an effective way to estimate forest biomass and carbon. By the combination of data field measurement and allometric equation, the above ground trees biomass possible to be estimated over the large area. The objectives of this research are: (1) To estimate the above ground tree biomass and carbon stock of forest cover in Lore Lindu National Park by combination of field data observation, allometric equation and multispectral satellite image; (2) to find the equation model between parameter that determines the biomass estimation. The analysis showed that field data observation and satellite image classification influencing much on the accuracy of trees biomass and carbon stock estimation. The forest cover type A and B (natural forest with the minor timber extraction) has the higher biomass than C and D (natural forest with the major timber extraction and agro forestry), it is about 607 ton/ha and 603 ton/ha. Forest cover type C is 457 ton/ha. Forest cover type D has the lowest biomass is about 203 ton/ha. Natural forest has high biomass, because of the tropical vegetation trees heterogeneity. Forest cover D has the lowest trees biomass because its vegetation component as secondary forest with the homogeneity of cacao plantation. The forest biomass and carbon estimation for each cover type will be useful for the further equation analysis when using the remote sensing technology for estimating the total biomass and for the economic carbon analysis.Forests play an important role in global carbon cycling, since they hold a large pool of carbon as well as potential carbon sinks and sources to the atmosphere.

Abstract As a conservation area, national parks play essential roles in environmental services provision and have the potential to support the REDD+ program. This study aims to estimate appropriate incentives for national parks based on carbon units by integrating the economic value of environmental services and carbon stock provided by the lowland dry forest ecosystem in Bogani Nani Wartabone National Park (BNWNP) consisted of North Sulawesi and Gorontalo areas. Carbon stock was estimated by establishing sample plots, including five carbon pools. While the economic valuation of environmental services includes biodiversity using the market approach, ecotourism using the zonal travel cost method, and water service using simulation water regulation services method and market approach. The total ecosystem carbon stock in BNWNP is estimated at 73.67 Mton. Meanwhile, the estimation of the economic value of environmental services is about IDR 70.57 trillion. Based on these results, the appropriate carbon values are IDR 683,308 and IDR 1,304,238 per ton carbon for the lowland dry forest ecosystem in Gorontalo and North Sulawesi areas. This result indicates that given its essential environmental services, the incentive for protecting national parks may exceed the carbon value used in result-based payment scheme in REDD+ initiatives that have been implemented.

Acacia decurrens, originally from Australia, is a woody plant that has become a concern in the erupted areas of Merapi volcano in 2006. The purpose of this study was to quantitatively describe the ecology of Acacia decurrens, and its invasive potential. Vegetation analysis was carried out in four areas of Mount Merapi National Park (TNGM), namely Kalikuning, Kaliadem, Plawangan and Pranajiwa. Ordination using the Non Metric Multidimensional Scaling (NMDS) method and Canonical Correspondence (CCA) and Spearman's bivariate correlation were carried out in data analysis. The results of NMDS analysis (2D stress = 0.14) showed that open areas due to eruption in Kaliadem are now dominated by A. decurrens. The results of the analysis also showed a significant negative correlation (Spearman rho = 0.6) between the abundance of A. decurrens and the level of species diversity in the sampling location. From the results of CCA, A. decurrens in the seedling stage appeared to coexist with other types of ground cover such as Alangium javanicum and Araliaceae. But in the tree phase, this species tended to form pure stands and only occasionally appeared to live side by side with other types of Fabaceae such as Albizia lopantha. Tree-level A. decurrens seemed to prefer sites with lower pH levels while A. decurrens seedling levels were more commonly found in sites with higher pH. Acacia decurrens have the potential to become a weed in TNGM due to its dominant distribution and tendency to decrease the level of species diversity in TNGM.

Merapi volcano as one of national park is an ecotourism site which is very potential to visit. Information about species diversity for a national park is very important especially if its area fluctuated susceptibly. Two years after 2010 Merapi eruption, there are no research about species diversity and evenness of Anuran in that place. The research is carried out during June-November 2012 which is dry season. The objective of this research is to study the species diversity and evenness of Anuran in southern slope of Mount Merapi. The research is carried out in 6 locations; those are Kali Kuning, Telogo Muncar, Telogo Nirmolo, Petak Pitu, Bukit Turgo, and Bukit Plawangan. We used Visual Encounter Survey (VES) method combined with transect in Kali Kuning, Telogo Muncar, and Petak Pitu. VES method combined with time search in Telogo Nirmolo and Bukit Turgo. VES method combined with track exploration in Bukit Plawangan. Species diversity is analyzed with Shanon-Wiener diversity index. Species evenness is analyzed with Pielou evenness index. Total individuals each species is counted to know species abundance. Species diversity of anuran in southern slope of Mount Merapi is consisted of 12 species’ which is distributed in 6 locations. The highest diversity and evenness of anuran is at Bukit Turgo (H’=1.31; E=0.94). The lowest diversity and evenness of anuran is at Petak Pitu (H’=0.49; E=0.3). Species diversity of anuran in southern slope of Mount Merapi is low (Bukit Turgo and Kali Kuning) and very low (Bukit Plawangan, Telogo Muncar, Telogo Nirmolo, and Petak Pitu). Species evenness of anuran in southern slope of Mount Merapi is stable (Telogo Nirmolo and Bukit Turgo), still labil (Bukit Plawangan, Kali Kuning, and Telogo Muncar), and oppressed (Petak Pitu).

Organic Carbon Stock

Abstract. Research carried out on soil organic carbon stock (SOCS) in the Sudano-Sahelian region of Cameroon is very rare. The few existing studies are mostly available in reports and concern in most cases carbon stocks in plant biomass. In order to contribute to the documentation on soils in this part of the country, the present work was designed to evaluate the SOCS in the main soil types and the influence of environmental factors and soil properties on these stocks under the natural dry tropical area of the Sudano-Sahelian zone of Cameroon. The study was undertaken in four sites, including three natural forest reserves (Laf, Zamai, Kosohon) and one national park (Mozogo), located at different latitudes. Three replicates were collected at each site, giving rise to three sampling points chosen per site, from 0 to 75 cm depth, for the determination of SOCS. At each sampling point, soils were sampled using depth increments of 25 cm from the surface. The studied area is covered by Haplic Vertisols, Dystric Arenosols, Dystric Leptosols and Dystric Planosols. Total SOCS (T-SOCS) content, which refers to a depth of 75 cm, decreases with increasing latitude, with 249±26.26 Mg ha−1 in Vertisols at Laf forest reserve most southerly located, 199±8.00 Mg ha−1 in Arenosols at Zamai forest reserve, 166±16.63 Mg ha−1 in Leptosols at Kosohon forest reserve and 161±8.88 Mg ha−1 in Planosols at Mozogo national park most northerly located, regardless of the altitude. No significant correlation was noted between T-SOCS and the altitude. A good correlation was noted between precipitation which decreases with increasing latitude and T-SOCS, indicating the importance of climate in the distribution of T-SOCS in the study area, which directly influences the productivity of the vegetation. More than 60 % of the SOCS was stored below the first 25 cm from the soil surface, a peculiarity of SOCS in drylands. The SOCS in the Sudano-Sahelian area of Cameroon is mainly influenced by climate and vegetation.
