Ecological Considerations for Using Dipterocarps for Restoration of Lowland Rainforest in Southeast AsiabackgroundIn this article, the authors present ecological factors that should be considered when engaging in dipterocarp forest restoration in Southeast Asia. Because many dipterocarps are insect-pollinated, have poor seed dispersal, have low density of reproductive adults, and have recalcitrant seeds, planting of nursery-reared tree seedlings could increase the ability of dipterocarp forests to regenerate.

Biomass Equations for Tropical Tree Plantations Using Secondary Data from the PhilippinesbackgroundThis study advances models for biomass estimation of tropical forests using equations verified by sampling in Philippines plantations. Evidence-based, site-specific equations for biomass estimation can avoid the need for frequent destructive sampling. Open access copy available |
Potential of Agroforestry and Plantation Systems in Indonesia for Carbon Stocks: an Economic PerspectivebackgroundOpen access copy available |
Forest Plantations on Imperata Grasslands in Indonesia: Establishment, Silviculture, and Utilization PotentialbackgroundThis dissertation presents results from multiple studies of reforestation on areas dominated by Imperata cylindrica grass in South Kalimantan, Indonesia. Open access copy available |
Farm Forestry: An Alternative to Government-Driven Reforestation in the PhilippinesBackgroundThis study reviews literature and various case studies about growing trees at the farm level by rural farmers. In the Philippines, millions of dollars have gone to employ people to plant trees as part of reforestation programs while only about 10% of those planted areas are successful. The authors assert that paying people to plant trees is unsustainable and often hindered by the lack of prompt release of funding. Available with subscription or purchase |
Effects of Nutrient Addition, Mulching and Planting-Hole Size on Early Performance of Dryobalanops aromatica and Shorea parvifolia Planted in Secondary Forest in Sarawak, MalaysiabackgroundIn this study, three methods were tested for their ability to improve growth of dipterocarp seedlings planted in west Sarawak, Malaysia.

Evaluation of Reforestation Potential of 83 Tree Species Planted on Imperata cylindrica Dominated Grassland – A case Study from South Kalimantan, IndonesiabackgroundIn this study, 83 tree species (native and exotic) were tested for their growth and survival in species selection trials in South Kalimantan, Indonesia.

Rehabilitation of Degraded Forest with Shorea leprosula and S. selanica CuttingsbackgroundThis article describes limits to dipterocarp-based reforestation due to irregular flowering pattern, short seed storage period, and uncertain planting techniques in Southeast Asia. In West Java, Indonesia, the authors test the effectiveness of vegetative propagation for two species of fast-growing dipterocarps: Shorea leprosula and Shorea selanica. Open access copy available |
Variability and Grouping of Leaf Traits in Multi-Species Reforestation (Leyte, Philippines)backgroundResearch on functional diversity is an important part in ongoing efforts to identify appropriate native tree species for reforestation projects. Increasing understanding of easy to measure physiological characteristics, such as specific leaf area, can help predict a variety of functional characteristics as well as growth perfromance.

Landscape Rehabilitation of Degraded Tropical Forest Ecosystems: Case Study of the CIFOR/Japan Project in Indonesia and PerubackgroundThe CIFOR/Japan project on tropical forest restoration involves three principal components: 1) evaluation of logging impacts on forest systems, 2) development of methods for the restoration of logged and degraded forests, and 3) development of silvicultural practices for degraded forests. Open access copy available |
The Sabah Biodiversity Experiment: A Long-Term Test of the Role of Tree Diversity in Restoring Tropical Forest Structure and FunctioningbackgroundThis article details the initial stages of an experiment in Borneo which aims to study the relationship between tree diversity and lowland dipterocarp rainforest functioning during restoration after selective logging. Open access copy available |
Creative Ecology: Restoration of Native Forests by Native TreesbackgroundThis article describes how the "native forests by native trees" restoration method used in Japan was applied to reforestation in Malaysia, and later in Brazil, Chile, and parts of China. Open access copy available |
Helping Forests to Help Themselves—Accelerating Natural RegenerationbackgroundThis chapter walks through the basic techniques of accelerated (or assisted) natural regeneration (ANR), describing when it is appropriate, when it should be combined with other techniques, how to increase the seed rain, and areas of needed research. Open access copy available |
Manual of Reforestation and Erosion Control for the PhilippinesbackgroundThis manual provides a detailed guide to reforestation, including information about species selection, nursery techniques, site preparation and plantation design, weed and fire control, stand improvement and other practical aspects of establishing and managing tree plantations. Additionally, there is a large portion devoted to erosion control, using trees and engineered structures to stabilize slopes and decrease the velocity of water runoff. Open access copy available |

Growth of dipterocarp seedlings in artificial gaps: An experiment in a logged-over rainforest in South Kalimantan, IndonesiaBackgroundRegeneration of dipterocarps following logging has become a crucial issue in tropical forest management. Secondary forest frequently and rapidly replaces dipterocarps in large logged-over patches. If unmanaged, these secondary forest patches are often composed of unmerchantable early-succession species. It has been hypothesized that dipterocarps grow most successfully in small gaps. Available with subscription or purchase |
Appropriate Measures for Conservation of Terrestrial Carbon Stocks: Analysis of Trends of Forest Management in Southeast AsiabackgroundThe ASEAN countries of Southeast Asia have seen rapid deforestation and subsequent carbon losses in the past few decades, as lands are cleared for other land uses. This study analyzes the implications of different land management scenarios on carbon stocks. Open access copy available |
Rehabilitation of Degraded Forests in Thailand: Policy and PracticebackgroundThis article provides an overview of efforts to rehabilitate degraded lands in Thailand. The authors synthesize articles and government policies to understand different plans of action for the government. Based on their analyses, they outline the challenges facing forest rehabilitation efforts and specific areas that need improvement. Open access copy available |

The Value of Rehabilitating Logged Rainforest for BirdsBackgroundThis study examines a lowland, dry dipterocarp forest in Sabah, Malaysia that had been selectively logged in 1988-89. One area was rehabilitated (enrichment planting and liberation cutting of vines, bamboos, and noncommercial species). This area was surrounded by a naturally reforesting area. The authors suggest that rehabilitation of selectively logged forests is a more effective carbon sink than plantations. Available with subscription or purchase |
