Abstract

We studied the floristic composition and structure of the logged-over peat swamp forest in the PT National Sago Prima of PT Sampoerna Agro Tbk. group for future management of the conservation area that has been set aside by the company. In January - February 2012, 25 quadrats of 20 m x 20 m were laid out systematically along a transect, thus covering a sampled area of 1-ha. The results showed that the study site was a regenerating and developing secondary peat swamp forests having high plant species richness. The total number of species recorded was 73 species of 38 families, consisting of 49 species (30 families) of trees (DBH? 10 cm ), 42 species (24 families) of saplings (H > 1.5 m and DBH < 10 cm), and 41 species (27 families) of seedlings and undergrowth. Tree density was 550 individuals/ha, and total tree basal area was 18.32 m2. The Shannon-Wiener’s Diversity Index for trees was high (3.05) Two tree species with the highest Importance Values (IV) were Pandanus atrocarpus (IV= 45.86 %) and Blumeodendron subrotundifolium (22.46 %). The tree families with the highest IV were Pandanaceae (45.86), Myrtaceae (40.37), and Dipterocarpaceae (39.20). Forest structure dominated by trees with a diameter below 20 cm amounting to 408 trees/ha (74.05%). and D and E strata with height of less than 20 m, and density of 431 trees/ha (78.36%). Jaccard Similarity index among species, showed strong association between Pandanus atrocarpus and Blumeodendron subrotundifolium and based on this association combined with high IVs, the two parameters of species characterized the forest, hence the forest could be designated as the Pandanus atrocarpus--Blumeodendron subrotundifolium association. Primary forest species with high economic values were still present in the forest. Eleven species can be included in the IUCN Red List, of which Shorea rugosa is in the category of Critically Endangered), Shorea tesymanniana Endangered and Gonystylus bancanus vulnerable, hence they should be protected.

Abstract

In order to reduce deforestation, the Government of Indonesia has introduced several initiativies, including a Hutan Desa (village forest) program to bring local communities to become actor in the forest management. The Reduced Emissions from Deforestation and Forest Degradation plus (REDD+) and Payment for Environmental Services (PES) scheme for the hutan desa is one of the alternative scheme to provide economic incentives for their effort to manage their forest sustainably. This study aims to evaluate the impact of the initiation of REDD+ and PES funds for hutan desa to deforestation and community wellbeing. The impact to deforestation is measured through quantitative approach by comparing quantitatively forest cover on 1070ha of village forest through satelite image analysis. The impact to community wellbeing is measured through participatory wellbeing assessment involving 30 informants during a focus group discussion. An attribution to the variables are conducted qualitatively by in-depth interviews to 25 key informants. The result shows eventhough the benefit provided by the initiation of REDD+ and PES (the money) is much less than the opportunity cost, the community is still accepting the scheme and succeeds reducing deforestation. However, the benefit is not sufficient enough yet to improve community wellbeing.
