The Restoration Diagnostic: A Method for Developing Forest Landscape Restoration Strategies by Rapidly Assessing the Status of Key Success Factors

Background

This report outlines the social, economic, and environmental benefits that forest restoration landscape restoration can have in countries with degraded or deforested landscapes.

Effet de la lumière des trouées de la canopée sur le potentiel et la dissémination de Gnetum africanum dans les écosystèmes forestiers congolais

This article examines Gnetum africanum, a species of commercial interest in Central African forests. The authors Iinvestigated the importance of light in Gnetum africanum dispersal and regeneration by analysing the effect of canopy gaps on Gnetum africanum in different forest types. Ther determined that Gnetum africanum is a shade tolerant species that needs shade to germinate and prefers low light levels as juveniles.

Croissance et assimilation nette foliaire de jeunes plants de dix arbres de la forêt guyanaise, cultivés à cinq niveaux d'éclairement

background

This study assesses the growth of ten species of tropical rainforest trees under 5 different light conditions.

Conclusions & Takeaways

The authors find that juveniles of most species did best in 25-45% sun light conditions and that the lowest light levels severely decrease growth across species.

Explorer la banque de graines du sol pour mieuxcomprendre la dynamique de régénération des forêtstropicales africaines (synthèse bibliographique)

The authors provide a review of the current knowledge of soil seed banks in African tropical forests. They argue that increased knowledge of soil seed banks will lead to better understanding of forest regeneration and therefore more successful reforestation efforts. Finally, the authors call for better characterization of seed banks based on forest community, as this could aid reforestation and sustainable forest management efforts in African tropical forests.

Restoration Ecology of Lowland Tropical Peatlands in Southeast Asia: Current Knowledge and Future Research Directions

Background

While there has been extensive research on northern peatlands, there has been limited studies that have studied tropical peatlands. Southeast Asia in particular has experienced significant deforestation and degradation of peatlands, thus resulting in a rise of landscape-scale restoration projects.

Establishment of Tree Seedlings in the Understory of Restoration Plantations: Natural Regeneration and Enrichment Plantings

Background

This study investigates how seedling establishment is affected in the understory of restoration sites of different ages (10,22 and 55 year-old) within the Brazilian Atlantic Forest. It also assesses some of the environmental microsite conditions that influenced the stand dynamics process.

Variation in the Population Structure Between a Natural and a Human-Modified Forest for a Pioneer Tropical Tree Species not Restricted to Large Gaps

Background

The study was conducted in a permanent plot in a primary forest at Caetetus Ecological Station (CES), and in an early successional forest adjacent to the state reserve at Torrão de Ouro Farm, state of São Paulo, Southeast Brazil. This forest originally covered nearly the entire plateau in the state of São Paulo, and it is currently the most threatened forest in the State due to past fragmentation.

Changes in vegetation structure and composition along a tropical forest chronosequence: implications for wildlife

Background

Changes in tropical forest structure and species composition that occur during regeneration following land abandonment may have important consequences for wildlife populations. Many animals rely on forest resources as sites for foraging, nesting, and protection that may vary in abundance in forests of different ages. This study examines aspects of forest composition and structure thought to be important to wildlife along a tropical moist forest chronosequence in the Barro Colorado Nature Monument of central Panama.

Effects of Logging, Liana Tangles and Pasture on Seed Fate of Dry Forest Tree Species in Central Brazil

Background

This article examines seed germination, predation, removal, and death for six different species in undistured forest, logged forest and an active pature. Because gaps created from logging are often overrun by liana tangles, it also compares seeds planted under patches of lianas (low forest) and seeds under patches of mature forest (high forest).
