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.

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.

Poverty reduction in the Doi Mae Salong Landscape

Background

The Doi Mae Salong Landscape has experienced deragadation in ecosystem services due to a variety of reasons along with the significant poverty and high risk to climatic variations. The IUCN partnered with the Supreme Commander’s Office of the Royal Thai Armed Forces to pursue forest restoration and support local livelihoods. The program ran from 2010 to 2013 in the Chiang Rai Province of Thailand.

Variability and Grouping of Leaf Traits in Multi-Species Reforestation (Leyte, Philippines)

background

Research 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.
