Amelioration of degraded rain forest soils by plantations of native trees

background

While much has been studied about the ability of tree growth to improve degraded soils in temperate zones, less is known about the impacts of tree growth on degraded soils in tropical zones.

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.

Carbon Sequestration in Pastures, Silvo-Pastoral Systems and Forests in Four Regions of the Latin American Tropics

background

77% of agricultural land in the tropical Americas is used for pasture (including silvo-pasture and Argo-silvo-pasture), making carbon stocks in this land type an important consideration. This paper presents three-year research results on the evaluation of soil carbon stocks (SCS) in long-established pasture and silvo-pastoral systems (10-16 years under commercial production), native forests and degraded land in four regions of tropical Americas.

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.

Early effects of four fast-growing tree species and their planting density on ground vegetation in Imperata grasslands

Background

The study aimed to test the early effects of four successful reforestation 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 Imperate grasslands. The four fast-growing exotics tree species used in the study were Acacia mangium, Acacia crassicarpa, Gmelina arborea, and Paraserianthes falcataria.

The Future of Plantation Forests and Forest-Based Industry in Indonesia

Background

The author explores the historical development of plantation forests in Indonesia and then concludes that a stable governmental framework is crucial to facilitate sustainable plantation forest development. He also highlights the importance of cooperation with the processing industry and the alignment of the latter to potential markets.

Early Growth of Native and Exotic Trees Planted on Degraded Tropical Pasture

background

This study describes the potential of two exotic and five native tree species to restore degraded land in Costa Rica.

Research Goals & Methods

Thirty blocks were established over 25 hectares of abandoned cattle pasture and tree height was measured at 3 and 7 years and tree survival was measured after 7 years.

New Options for Land Rehabilitation and Landscape Ecology in Southeast Asia by "Rainforestation Farming"

background

The authors describe a methodology for reforestation called "Rainforestation Farming" developed in the Philippines in the 1990s to restore forest cover on degraded lands covered with Imperata cylindrica grass in the Visayas region

Manual of Reforestation and Erosion Control for the Philippines

background

This 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.

Species-Specific Tree Water Use Characteristics in Reforestation Stands in the Philippines

Background

The need for reforestation is becoming increasingly evident in countries like the Philippines where deforestation has lead to a scarcity of wood and other forest commodities. One concern with reforestation is the reduction in streamflow and groundwater recharge as trees move water from the ground into the atmosphere.

Early Growth Performance of Native and Introduced Fast Growing Tree Species in Wet to Sub-Humid Climates of the Southern Region of Costa Rica

background

The authors present information on the growth of seven-year-old native tree species planted in abandoned pasture with low fertility acidic soils in the southern pacific region of Costa Rica.

Research Goals & Methods

The study evalutes trees in four ecoregions of varying elevation and precipitation.

Selecting framework tree species for restoring seasonally dry tropical forests in northern Thailand based on field performance

Background

Framework tree species are indigenous forest tree species, planted to complement and accelerate natural regeneration of forest ecosystems and encourage biodiversity recovery, on degraded sites. This study tests the extent to which 37 native forest tree species might act as framework tree species to accelerate recovery of evergreen, seasonal forest in a degraded upper watershed in Doi Suthep-Pui National Park in northern Thailand.
