Secondary Forest Regeneration under Fast-Growing Forest Plantations on Degraded Imperata cylindrica Grasslands

Background

This study compares the regeneration of native tree species under the canopy of tree plantations, riverine areas, and uncultivated grassland areas in the Riam Kiwa plantation area of South Kalimantan, Indonesia. This area has a distinct dry season and deeply weathered, acidic soils, and is considered good for forest plantations.

Reforesting “Bare Hills” in Vietnam: Social and Environmental Consequences of the 5 Million Hectare Reforestation Program

Background

Large-scale rehabilitation and reforestation of Vietnam has been promoted by the Socialist Republic of Vietnam, but unexpected outcomes have, in some cases, harmed local communities. Within this case study from northern Vietnam, lands classified as "barren hills" actually contained a number of economically-important nontimber products which local communities and individuals, particularly poor households and women, were reliant on. These nontimber products included fuelwood, medicines, construction material, food, and pasture.

Does Tree Planting Change Minds? Assessing the Use of Community Participation in Reforestation to Address Illegal Logging in West Kalimantan

background

Gunung Palung National Park in West Kalimantan, Indonesia has experienced illegal logging and fires that led to degradation and conversion of forests to grasslands in a state of arrested succession. A local NGO named Alam Sehat Lestari (ASRI) began a restoration effort to restore degraded forest areas and provide jobs to local community members that might otherwise participate in illegal logging.

Early Effects of Four Fast-Growing Tree Species and Their Planting Density on Ground Vegetation in Imperata grasslands

background

This study aims to test the success of fast-growing exotics tree species and alternative planting densities on the development of ground vegetation. The study was conducted in Riam Kiwa, South Kalimantan, Indonesia in Imperata grasslands. The four fast-growing exotic tree species used in the study were Acacia mangium, Acacia crassicarpa, Gmelina arborea, and Paraserianthes falcataria.

Seeding ecological restoration of tropical forests: Priority setting under REDD+

Background

Tropical deforestation continues to be the major driver of biodiversity loss and a considerable contributor to climate change. Increasing numbers of forest-dependent rural poor rely on degraded forest for their livelihoods. Ecological restoration of tropical forests has the potential to not only contribute to biodiversity conservation and climate mitigation, but also poverty alleviation. REDD+ provides a potentially powerful mechanism for supporting ecological restoration of tropical forests in developing countries.

Effect of Site Preparation and Initial Fertilization on the Establishment and Growth of Four Plantation Tree Species used in Reforestation of Imperata cylindrica (L.) Beauv. Dominated Grasslands

background

This study describes site preparation techniques for the regeneration of four native tree species in Imperata cylindrica- dominated areas of South Kalimantan, Indonesia.

Goals & Methods

Two trials were run. The first one examined the effects of strip plowing and complete plowing on the performance of Acaca mangium. The second trial compared the effects of complete plowing, herbicide treatment and fertilization (NPK) on four tree species commonly use in Imperata grassland reforestation.

Financial, Economic and Environmental Profitability of Reforestation of Imperata Grasslands in Indonesia

background

This study assesses the profitability of roundwood production in forest plantations established on Imperata grasslands in South Kalimantan, Indonesia.

Research Goals & Methods

This study uses the discounted cash flow method on the Riam Kiwa reforestation trial area. It also explores the importance of fiscal incentives to financial profitability of roundwood production in forest plantations established on Imperata grasslands.
