Native trees and shrubs for the productive rehabilitation of tropical cattle ranching lands

Background

Latin America, much like the rest of the rest of the world, has experienced significant deforestation rates. In this region, the primary driver has been large-scale land conversion to unsustainable uses, like industrial cattle ranching and agriculture. This article recognizes the deep-rootedness of cattle in Latin American economies and cultures, yet stresses the need to shift the paradigm by adopting intensive silvopastoral systems (ISS) that utilize native species.

Conserving Biodiversity in a Complex Biological and Social Setting: The Case of Colombia

Background 

Colombia is known for its immense biological diversity and complexity. This article examines three of the primary causes of these characteristics, including history, geogrpahy, and evolution along with the context of the country's conservation efforts. The auhors then identified threats based on trends that emerged from these themes.

Forest Landscape Restoration: Progress in the Last Decade and Remaining Challenges

Background

Defined in 2000, forest landscape restoration (FLR) has recently been actively promoted as a means to provide both ecolocial and societal benefits. This article aims to reflect on the evolution of FLR since 2000, using a framework of 13 key issues put forth in 2005. It identifies both progress and challenges and provides suggestions for steps forward.

Toward a post‐conflict Colombia: restoring to the future

Background

After emerging from over 60 years of armed conflict, Colombia is positioned to pursue ecological restoration. Through this pursuit, the country will restore ecosystem services that were severly impaired, thus restoring both natural and social capital that can actively contribute to the peace-building process. Moreover, the Colombian government has also undertaken national and international engagements that commit to reforesting and restoring the country's ecosystem. This article provides suggested goals and guidelines to aid in these ambitious restoration efforts.

Accelerating tropical forest restoration through the selective removal of pioneer species

background

This study presents initial findings on the impact of thinning on recovery of a selectively logged secondary forest in Sumatra. The study tests the hypothesis that thinning of pioneer species will produce stands with greater proportional basal area of late-successional species, effectively accelerating succession of the stand.

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.

Screening Trial of 14 Tropical Hardwoods with an Emphasis on Species Native to Costa Rica: Fourth Year Results

Background

A lack of silvicultural information on native timber species in the tropics has contributed to the propogation of fast-growing exotic tree species in reforestation efforts. The plantations evaluated at the La Selva Biological Station in Costa Rica were considered marginal lands with low input of forest maintenance, reflecting the conditions of many lands that farmers would use for reforestation.

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.

A tree-based approach to biomass estimation from remote sensing data in a tropical agricultural landscape

background

Due to increased global dominance of agricultural lands in the tropics, methods to establish biomass and carbon in agricultural areas are necessary for monitoring and modeling global C stocks. Since tropical agriculture often includes some tree cover, the study seeks to develop above ground biomass estimates using landscape-scale surveys with LiDAR in comparison to plot-level data.
