Bangkok’s Inner Orchard (BIO), located in the west peri-urban area of the city, provides both fresh products and ecological benefits to its inhabitants. Although this unique forest-like cultivation of mixed fruit trees growing on dikes has the potential to become an urban forest, it has never been thoroughly investigated. Urban expansion is a threat to this orchard. Sustainable cities must maintain a balance between development and the environment. In this study, six orchards were surveyed by collecting data on tree species, plant height, crown width, and location and analyzed to identify the orchard areas covered by forest canopy and clarify the forest structure and tree species diversity in the orchards. Overall, 98.64% of the forest canopy within the orchard area was evaluated using cover analysis. Analysis of the forest structure of the BIO revealed that the average tree height was greater than that of common orchard trees. Tree diversity analysis showed an average Shannon index value of 2.53, indicating mid-range diversity. Older orchards showed a greater diversity of fruit tree species, whereas newer orchards, replanted after major flood and drought events, showed a lesser diversity of fruit tree species. In order to protect BIO on the long-term, it is essential to identify and apply appropriate conservation strategies. Including BIO areas in the Bangkok greening scheme would cause rapid increases in the green area per capita ratio. Both urban food forest and urban agriculture concepts could be applied to existing BIO orchards, which represent new urban green area types. BIO thus has the potential to act as an urban forest and tree diversity hotspot for Bangkok.

“…Planted forest typically refers to the forest that is primarily made up of trees that have been planted and/or intentionally seeding. Planted forests provide many benefits including traditional timber and fibre production, economic development, and employment in rural areas [2] and have been identified as a key means to fight climate change in the short to medium term, restore degraded land, and maintain sustainable ecosystem functions and services [3][4][5][6]. In the context of a broader geographic and economic context, wellmanaged planted forests can contribute to sustainable development [7].…”

Forest covers 4.06 billion hectares (ha) or 31% of the total land area worldwide, where 93% (3.75 billion ha) are natural regenerating forests and the remaining 7% (294 million ha) are planted forests. Eucalyptus spp., being one of the most important plantation species, has been planted in 95 countries around the world, and the area of plantation has exceeded 22.57 million ha. In the southern hemisphere, it is a significant industrial fast-growing tree species. These plantations serve as a valuable resource for the timber and fibre-based industries. Eucalyptus is the main fibre resource for the pulp and paper industries in developed countries. Timber extracted from the planted eucalyptus trees has long been used for solid wood and its fibres were used for manufacturing medium-density fibreboard. In comparison to most softwood species, Eucalyptus timber is reported to have a higher rigidity, making it ideal for manufacturing structural products. Therefore, this paper presents a review and analysis of the recent state of research on the utilisation of planted eucalyptus for engineered wood products (EWPs) manufacturing. This study investigated Eucalyptus-based EWPs such as particleboard, fibreboard, oriented strand board, laminated veneer lumber, plywood, glue laminated lumber, and cross-laminated lumber. The feasibility of using planted Eucalyptus in the production of EWPs, as well as the challenges encountered, was also discussed.

“…Planted forests are a major component of ongoing forest landscape restoration (FLR) initiatives that seek to strategically increase tree cover in degraded or deforested landscapes (e.g., Lamb et al, 2012;Dave et al, 2019;Brancalion and Holl, 2020;Korhonen et al, 2020). Plantation forestry has been heralded as a "win-win" that both provides opportunity for rural landowners to generate income and also preserves the ecosystem services of natural forest cover (FSC, 2012;Kissinger et al, 2012), but these potential benefits are not always realized.…”

Large areas of the Panama Canal Watershed have been converted to monocultures of teak (Tectona grandis), a non-native timber species that is generally not providing hoped-for economic and ecological benefits of Forest Landscape Restoration. Enrichment planting offers a potential strategy for revitalizing these underperforming plantations through the addition of high-value, native species to the understory, but more information is needed to guide implementation and management in this region and other tropical areas. We assessed the performance of six promising native species (Byrsonima crassifolia, Dalbergia retusa, Dipteryx oleifera, Hyeronima alchorneoides, Platymiscium pinnatum, Terminalia amazonia) as an enrichment planting in teak plantations, and specifically considered how light availability, crowding pressure and annual fertilization affected seedling performance, we measured survival and growth for the first 30 months post-planting for ∼3,000 seedlings; half received annual fertilization and half did not. We found that growth rate did not significantly affect survival among- or within-species, except for a positive relationship for D. oleifera. Overall seedling survival was high (83%), and, while species varied widely, there was not a strong effect of light, crowding or fertilization on survival. In contrast, overall growth of species was significantly affected by these factors. Across all species growth was negatively related to crowding and positively related to light availability and fertilization. There were among-species differences; while all but one species (D. oleifera) were negatively affected by crowding, only half responded positively to light availability (D. retusa, P. pinnatum, and B. crassifolia) and fertilization (D. retusa, P. pinnatum, and T. amazonia). Our findings suggest that all study species except for B. crassifolia, which suffered unacceptably high mortality, have high potential for use in enrichment planting in Panama teak plantations. Among-species differences in response to fertilization and growing environment highlight the need for continued studies to establish specific silvicultural guidelines for species in the enrichment planting context.
