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.

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.

Genetic Consequences of Tropical Second-Growth Forest Regeneration

Background

This article is an examination of the genetic impacts of old-growth deforestation among 24 year-old second-growth Iriartea deltoidea, a canopy palm, in a lowland Costa Rican forest. Iriartea is widely distributed throughout neotropical rainforests and displays a diverse range of size classes in mature forests. This species recolonizes second-growth forests with newly generated seeds, which are dispersed by birds and mammals.

The Potential for Species Conservation in Tropical Secondary Forests

Background

The importance of tropical secondary forests for conserving biodiversity increases with the degradation of old-growth forests, yet little is known about the role that these forests play in promoting biodiversity. Geospatial and temporal factors influence the role of secondary forests in species conservation, and this synthesis of case studies evaluates the significance of these factors on regional and landscape scales.

Natural regeneration as a tool for large‐scale forest restoration in the tropics: prospects and challenges

background

This article is a review of natural regeneration in the context of large-scale forest restoration in the tropics. The article provides case studies of successful natural regeneration, pointing out the side benefits of genetic adaptation, traditionally-used species, and local biodiversity. These features also bring greater ecosystem resilience.

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.

Strategic Insights for Capacity Development on Forest Landscape Restoration: Implications for Addressing Global Commitments

Background

Global initiatives, like the Aichi Targets and Bonn Challenge, have recognized capacity development as a key strategy in achieving the large-scale restoration goals, particularly those that utilize the complex forest landscape restoration (FLR) approach. Still though, the concept of capacity development is largely undefined. This article seeks to answer key questions in regards to integrating capacity development strategies into FLR projects.

Restoring tropical forests from the bottom up

Background

Written in 2017, this article acknowledges that numerous countries around the world have committed to restoring large areas of forest in the next decade or so. Given these challenging targets, the authors seeks to understand how they can be met given competing land uses. She draws on several case studies to answer this broad question, including ones from Brazil, Mexico, and Colombia.

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.
