Abstract

Trees always appear as green building in a city, it growth side by side with various types of soild infrastructures and often ended with a conflict. Many cities in Indonesia experience the conflicts, especially between road and trees, which resulting risks to public and high restoration cost, but this urban green dynamic has not scientifically explored yet. We initiates a study on the dynamics of tree conflicts with road infrastructure in Padang City, a representative city in Indonesia with numerous conflict events. Species of tree, diameter, and distance to infrastructure were measured along 1.5 km of secondary and 1.5 km of primary road. There were 524 trees belong to nine species were found along 3 km road, and 35% of the trees were conflicted with the infrastructure. Primary road was dominated by small trees and was only causing 11% conflicts, while secondary road was dominated by large trees and 71% were conflicted. Number of conflict led by Pterocarpus indicus on both road types, while Swietenia mahogani was only conflicted with secondary road infrastructure and Dialium indum was only conflicted at primary road. Conflict of P. indicus at primary road was found at all diameter levels but at the secondary road the conflict was mostly associated to large trees. We also found many trees without conflict at all levels of diameter on both road types. Conflict of trees occurred at various distance to infrastructure and this found on both small and large trees. This study highlight that conflict between trees and infrastructure differed among species, size of tree diameter and conflict will always occurred when trees planted less than 2 m to infrastructure.

Abstract

This study aimed to investigate the floristic composition and the economic values of trees at the agroforestry parak in Maninjau, Tanjung Raya District. Four different villages were selected purposively according to the tree structure of parak, and each village represented each compass point surrounding the Maninjau Lake. 20 x 100 m plot was established at each sites, where all tree species were identified, and five owner of the parak at each location were asked about the fruiting and harvesting season, management and potential income from each of tree species. 20 tree species belong to 13 families were found across the sites, but only five were occured at all sites, while the others were missed at least from one site. Most species produced fruits with fruiting and harvesting season ranged from one to three times a year, but only seven species knew the income from selling the commodity. From all seven species, which varied on the harvesting season, the owner of each parak gained up to four million IDR per month. This study showed that variation of species and the harvesting season beneficial the owner of the parak and may kept the parak as primary or alternative livelihood.

Abstract

Non-timber forest products (NTFPs) are all types of forest products other than wood which provide multi-purpose benefits for the community, especially local communities who live around the forest. NTFP products are the main focus for alternative economic value of forests, NTFP demand can be used as a reference for management. One potential use of NTFPs is handicraft products that are bought and sold in economic centers, but the various types of NTFPs and their derivative products are still unknown. This research investigates the use of NTFPs for craft products in Padang Pariaman Regency, including the species of plants used, the types of craft products, and market potential. The survey was carried out in five places in Padang Pariaman Regency, selected using purposive sampling. Four types of NTFP plants were found which were used to make 27 types of craft products, namely Pandanus tectorius, Cocos nucifera L., Bambusa spp., and Calamus spp. Most handicraft products are produced from rattan plants, and the highest market potential is obtained by coconut-based craft products with a percentage of 83%. This data can be a reference for LPHN or forest managers around the Padang Pariaman Regency area.
