Direct Seeding to Restore Tropical Mature-Forest Species in Areas of Slash-and-Burn Agriculture

background

Direct seeding of three mature-forest species into areas of slash-and-burn agriculture was conducted to evaluate the germination and establishment of these species.

Research Goals & Methods

Different fallow times were evaluated, less than 5 years, 8-15 years, and greater than 50 years. Germination, survival, and growth for 1-2 years was evaluated for 1800 seeds planted per species (200 on each of three replicate sites per forest age).

Application of Assisted Natural Regeneration to Restore Degraded Tropical Forestlands

background

Assisted natural regeneration (ANR) has been proposed as an alternative restoration method that reduces the costs and scalability barriers of other restoration alternatives. This article describes the steps to applying ANR to disturbed ecosystems where forest succession processes have been halted by dominant grass or fern monocultures.

Ecological Considerations for Using Dipterocarps for Restoration of Lowland Rainforest in Southeast Asia

background

In this article, the authors present ecological factors that should be considered when engaging in dipterocarp forest restoration in Southeast Asia. Because many dipterocarps are insect-pollinated, have poor seed dispersal, have low density of reproductive adults, and have recalcitrant seeds, planting of nursery-reared tree seedlings could increase the ability of dipterocarp forests to regenerate.

Ecology of Mangrove Growth and Recovery in the Lesser Antilles: State of Knowledge and Basis for Restoration Projects

background

This article reviews the available information pertaining to mangrove ecology and restoration in the Lesser Antilles. On the islands of Martinique and Guadeloupe, mangrove species form monospecific vegetation belts parallel the shore. They follow an ecological gradient based on salinity and drainage, with the most halophylic being the Avicennia species followed by Rhizophora mangle and Conocarpus erectus, then Laguncularia racemosa with a lower salinity tolerance. In 1986 an experimental oil spill was created to study the ability of mangroves to regrow on polluted soil.

Tropical forest recovery: Legacies of human impact and natural disturbances

Background

Land-use history interacts with natural forces to influence the severity of disturbance events and the rate and nature of recovery processes in tropical forests. This perspective article highlights several trends in tropical forest recovery processes emerging from recent literature.

When and Where to Actively Restore Ecosystems?

Background

While conservation efforts around the world have focused on restoring degraded ecosystems to provide ecosystem services and benefit biodiversity, yet there has been an increasing recognition that certain ecosystems can rapidly recover without human intervention. This paper examines the question: what cases and to what extent should humans actively facilitate ecosystem recovery?

Selecting seed trees for a forest restoration program: A case study using Spondias axillaris

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. Spondias axillaris Roxb. (Anacardiaceae) is an exceptionally effective framework tree species for restoring seasonal tropical forest ecosystems to degraded sites throughout south and southeast Asia. This study identifies criteria for selection superior parent seed trees, based on nursery performance and field establishment, using Spondias axillaris as a case study.

Árboles de uso multiple en El Salvador: Un manual para propagación y reforestación (Multipurpose trees in El Salvador: a manual for propagation and reforestation)

Español

Antecedentes

El Salvador es uno de los países del hemisferio oeste con mayor deforestación . En el año  1998 este país contaba con tan solo el 2% de sus bosques originales en pie. A pesar del interés de la población en realizar actividades de reforestación, existe una gran falta de información sobre especies nativas adecuadas para este fin.
